• PHP 5.2 installation with GD on CentOS 6

  - by Pratik Thakkar

  I am trying to install PHP 5.2.17 on CentOS 6.2. I have downloaded RPMs from http://www6.atomicorp.com/channels/atomic/centos/6/i386/RPMs/ Problem is that the PHP RPM seems to have GD disabled by default. Hence in spite installing php-gd RPM, GD is disabled. Is there any way that I can enable GD. Atomicorp seems to be the only website that has PHP 5.2.17 RPMs. I am not an advanced user to be able to compile PHP. I would appreciate help on this.

• Fix for OpenSolaris with no gcc vs. Nexenta with no ext3

  - by Jake Wharton

  I'm attempting to migrate my server from linux to a Solaris variant during a hardware upgrade. The machine is based around an Abit AN-M2 board which has an NForce chipset. I have what seems to be a chicken-and-egg problem of sorts: OpenSolaris 2009.06 does not recognize the NIC and I cannot compile the drivers for it as it also lacks gcc. I haven't tested as to whether or not I can mount an ext3 partition yet but its moot if there is no networking. Nexenta 3.0b3 recognizes the NIC but I cannot get the ext3 drives mounted due to FSWfspart refusing to install. I do not know much about Solaris but I wager this is due to the fact that Nexenta is based around Debian as well. While I am reusing the mobo/CPU combo, I did just spent a lot of money on the other hardware around it and would very much like to get it up and running smoothly and quickly. Does anyone have any suggestions that are not: Get a new mobo/CPU Run another OS Use alternate NIC

• ffmpeg add two audio streams to video

  - by Tossin Hausen

  I tried this: ffmpeg -i /sdcard/video/transcode/video.avi -map 0:0,0 -i /sdcard/video/transcode/first.mp3 -map 1:0,1 -i /sdcard/video/transcode/second.mp3 -map 2:0,2 -acodec copy -vcodec py /sdcard/video/transcode/Output.avi to add two audio streams to one video file. But ffmpeg says the number of mappings should match the number of output streams. What is wrong here? I'm trying to work with an Android build of FFmepg "ffmpeg for android beta". "Does not work" means that this uncommunicative Android build of FFmpeg just stops without giving any error message. The -codec copy option does not work with this build. Now I tried the same set of files with the FFmpeg called command line tool that comes with Ubuntu 10. Something (can't say where it is from). The -codec copy option does not work with this FFmpeg too.

By the way, ffmpeg -i input_with_first_audio_stream.avi -i second.mp3 -acodec copy -vcodec copy output_two_audio_streams.avi -newaudio works with both versions of ffmpeg that I use, but the first audio stream is played too fast (x10 or more), while the second audio stream is played correct. Many thanks in advance and sorry for my unconventional question and outdated versions of ffmpeg. But I am a lamer and it is not so easy for me to compile from the source (especially for the Android version). I will try to compile an up to date version of ffmpeg with Ubuntu, but I don't have much free time.

• VMWare tools on Ubuntu Server 10.10 kernel source problem

  - by Hamid Elaosta

  After install and running the vm-ware config, the config needs my kernel headers to compile some modules, ok, so I'll give it them, but it just won't work. It asks for the path of the directory of C header files that match my running kernel. If I uname -r I get 2.6.35-22-generic-pae So I tell it the source path is /lib/modules/2.6.25-22-generic-pae/build/include and it returns "The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match your running kernel (version 2.6.35-22-generic-pae). ..I'm confused? can anyone offer suggestions please? I installed hte kernel source andh eaders myself using sudo apt-get install linux-headers-$(uname -r)

• MongoDB on FreeBSD

  - by Hartator

  We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions! Sources : http://groups.google.com/group/mongodb-user/browse_thread/thread/8131b7e5a5c710d9 http://ivoras.net/blog/tree/2009-11-05.a-short-time-with-mongodb.html

• xkb layouts not working (in KDE?) after upgrade from Ubuntu 9.10 to 10.04

  - by Alan

  I customised my keyboard layout in 9.10 by editing the appropriate /usr/share/X11/xkb/symbols/ file. After upgrading to 10.04 I noticed it had overwritten all my modifications, so I recovered the layout and overwrote the symbol file's base entry. Sadly KDE (and, presumably, the entire OS) seems to ignore the files altogether. The help files don't mention anything about modifying layouts anyway (and the layout switcher seems to be using setxkbmap, which uses the above path according to its man page), so I'm at a bit of a loss. Do I need to compile this into some other format somehow or how do I get it to work?

• Using the right folder for the right job. Article link, please?

  - by Droogans

  There are specific folders designed for specific tasks. /var/www holds your web sites, /usr/bin contains files to run your applications...yet I still find myself putting nearly all of my work in ~. Is it possible to overuse my home directory? Will it come back to haunt me? Anyone have a good link to an article of best practices for organizing your files so that they are placed in their "correct" place? Is there even such a thing in Linux? I am referring specifically to user-generated content. I do not compile applications from source, I use apt-get for those tasks. This article has a great introduction to what I'm looking for. Table 3-2, "Subdirectories of the root directory" is the sort of thing I'm looking for, but with more details/examples.

• install SSH2 (server?) on FreeBSD

  - by Robert Cabri

  At work we have freeBSD testmachine. And we have a PHP script that uses SSH2 protocol to connect with the freeBSD server. With this script I'm not able to connect to the freeBSD server. I wanted to install it, but I'm not sure where to find the right source to compile. The connection can be made with a different machine, but isntalling a new distro isn't the solution right now. I can connect to the server over ssh, but not with the ssh2 protocol in PHP (http://nl.php.net/ssh2).

• Why does Tomcat try to use the cache when compilation failed?

  - by etheros

  For some reason, it appears Tomcat is trying to hit its compilation cache when compilation failed. For example, if I create a JSP containing nothing but Hello, <%=world%>!, predictably, I get an error: org.apache.jasper.JasperException: Unable to compile class for JSP. Subsequent requests however alternate between this and org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP. Further, if I create a JSP containing Hello!, it of course works just fine. If I modify it contain Hello, <%=name%>!, the response alternates between the previously-mentioned compilation error, and the cached Hello!. What's going on?

• How to monitor a folder for changes, and execute a command if it does, on Windows?

  - by Camilo Martin

  There are similar questions for Linux and Mac, but I'm after a Windows solution here. The problem is as follows: I want to write several (js) script files in a folder, and have a program monitor that folder for file changes and new files being added, and run a command whenever that happens (to compile them all into one single file). The solution has to: Monitor both file changes and new files being added, in a folder. Run a command only if there is any change. It would be best if it either is a built-in solution (like a JScript or VBscript snippet), or something that does not require installation.

• Upgrading OpenSSL in CentOS 5.3

  - by Lin

  I want to use one IP to host many domains with individual SSL certificates (requires SNI). In CentOS 5.3, the latest version of OpenSSL I can find an RPM for is 0.9.8e, which does not support SNI. I want to upgrade to 0.9.8k but I can't find an RPM. I could compile from source, but if I try to remove the existing OpenSSL package through yum, it wants me to remove all packages that depend on OpenSSL (100+ packages). EDIT: I ended up installing 0.9.8k without overwriting the previous version. Now I both avoid breaking dependencies and can use SNI. Was this the best action?

• Error while loading shared libraries - libwebsock

  - by kittyPL

  Im trying to setup libwebsock, simple C websocket library. I followed the installation procedure from INSTALL file, everything went fine. Im able to compile test program given in the examples. But when I want to run my executable, wild error appears: ./echo: error while loading shared libraries: libwebsock.so.1: cannot open shared object file: No such file or directory I checked /usr/local/lib twice, libwebsock.so.1 exists and is doing very well. I also tried copying the lib to the echo folder (so its placed next to binary), still same error. It's quite funny for me: shadowz@Ubu:~/WebSocket$ ls echo echo.c echo.cpp libwebsock.so.1 shadowz@Ubu:~/WebSocket$ ./echo ./echo: error while loading shared libraries: libwebsock.so.1: cannot open shared object file: No such file or directory Any suggestions? Im running out of ideas...

• Weblogic 10.3 weblogic.jar classpath issues

  - by user63063

  I am upgrading an old WLS8.1 app to 10.3 (11g) My ant build includes only the new weblogic.jar in the compile classpath and the build runs with no issues but when I include weblogic.jar as a libeary in the IDE (Intellij) i see many unresolved imports (for example: weblogic.xml.xpath.DOMXPath) when I check the weblogic.jar I see that the classes are indeed missing from it. compiling with verbose revealed that by including weblogic.jar in the ant classpath, many other jars in the BEA_HOME/modules are loaded to the classpath as well (for example: com.bea.core.xml.weblogic.xpath_1.4.0.0.jar) Can anyone explain what is going on? How can I fix my IDE classpath - do I need to import all the module-jars? Many of the module jars seems like they are there to support old deprecated weblogic 8 APIs (like: weblogic.xml.xpath.DOMXPath) how can I exclude these modules from my ant build? (I want to expose the APIs I need to upgrade) Thanks, NY

• C language preprocessor behavior

  - by khanna_param

  There are different kind of macros in C language, nested macro is one of them. Considering a program with the following macro #define HYPE(x,y) (SQUR(x)+SQUR(y)) #define SQUR(x) (x*x) Using this we can successfully compile to get the result. As we all know the C preprocessor replaces all the occurrence of the identifiers with the replacement-string. Considering the above example I would like to know how many times the C preprocessor traverses the program to replace the macro with the replacement values. I assume it cannot be done in one go.

• Solaris 10 opencsw git package issue with bitbucket git hosting

  - by zephyrus00jp

  Has anyone tried using `git' from opencsw package in order to work with bitbucket source hosting service (under solaris10)? I tried to use git as the bitbucket documentation explains, and - under Debian GNU/Linux, it worked flawlessly as described, but - under Solaris 10, I got Authentication Failed message. I even tried to run truss to see anything is suspicious but could not find any smoking gun under solaris why it failed. ldd git-binary didnd't show anything suspicious either (except for the libcrypt library which could be a suspicious to think about export restrictions. Have they shipped incompatible version? BUT since the password is typed into https: connection, I suspect it is only a matter of web-level cryptography and should be universal these days.) I am now tempted to compile git suite under solaris 10, but I did find people who seem to be using git with bitbucket under solaris 10 and am wondering what could be wrong.

• can't execute scripts compiled with shc

  - by serilain

  I'm trying to use SHC to compile a shell script so that I can set the SUID bit on it and obfuscate what it's doing (I'm attempting to have it run as part of all new users' .bashrc). As a test, I wrote a script that's simply: #!/bin/bash env And compiled it using shc -r -f script.sh However, when I try to run the resulting script by simply doing ./script.sh.x, even after setting it to 777 (just for testing purposes), I get "Operation not permitted; killed" unless I run it as sudo (which I don't want to have to do). Am I running afoul of some Ubuntu permissions that won't let me run binaries created by shc? Thanks!

• A list of 'best practices' for extending the life between charges of a notebook battery.

  - by Tim Visher

  Hello Everyone, I'd like to compile a list of best practices for getting the most out of a single charge of a typical notebook battery (be it Li-Ion or Li-Poly). Sources would be great as well. I've heard, for instance, that the best things to do to improve battery performance (not the total lifetime of the battery, just single charge performance) are, in descending order of effectiveness: Turn your display all the way down. Turn off WiFi Turn off Bluetooth Spin down disks when they're not in use. etc… I'd like to get sources together for these and other tips for extending life-between-charge for any battery on any notebook (as these really are all about Demand Management rather than Life lime extension. Thanks!

• Link Error : xxx is already defined in *****.LIB :: What exactly is wrong?

  - by claws

  Problem: I'm trying to use a library named DCMTK which used some other external libraries ( zlib, libtiff, libpng, libxml2, libiconv ). I've downloaded these external libraries (*.LIB & *.h files ) from the same website. Now, when I compile the DCMTK library I'm getting link errors (793 errors) like this: Error 2 error LNK2005: __encode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 3 error LNK2005: __decode_pointer already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 4 error LNK2005: __CrtSetCheckCount already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 5 error LNK2005: __invoke_watson already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 6 error LNK2005: __errno already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 7 error LNK2005: __configthreadlocale already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Error 8 error LNK2005: _exit already defined in MSVCRTD.lib(MSVCR90D.dll) LIBCMTD.lib dcmmkdir Documentation: This seems to be a popular error for this library so, they do have a FAQ entry addressing this issue which ( http://forum.dcmtk.org/viewtopic.php?t=35 ) says: The problem is that the linker tries to combine different, incompatible versions of the Visual C++ runtime library into a single binary. This happens when not all parts of your project and the libraries you link against are generated with the same code generation options in Visual C++. Do not use the /NODEFAULTLIB workaround, because strange software crashes may follow. Fix the problem! DCMTK is by default compiled with the "Multithreaded" or "Multithreaded Debug" code generation option (the latter for Debug mode). Either change the project settings of all of your code to use these code generation options, or change the code generation for all DCMTK modules and re-compile. MFC users beware: DCMTK should be compiled with "Multithreaded DLL" or "Multithreaded DLL Debug" settings if you want to link the libraries into an MFC application. Solution to same problem for others: http://stackoverflow.com/questions/2259697/vscopengl-huge-amount-of-linker-issues-with-release-build-only says: It seems that your release build is trying to link to something that was built debug. You probably have a broken dependency in your build, (or you missed rebuilding something to release by hand if your project is normally built in pieces). More technically, you seem to be linking projects built with different C Run Time library settings, one with "Multi-Threaded", another one with "Multi-Threaded Debug". Adjust the settings for all the projects to use the very same flavour of the library and the issue should go away Questions: Till now I used to think that Name mangling is the only problem that may cause linking failures if its not been standardized. Just now I knew there are other things also which can cause same effect. Whats up with the "Debug Mode" (Multi-Threaded Debug) and "Release Mode" (Multi-Threaded)? What exactly is happening under the hood? Why exactly this thing is causing linking error? I wonder if there is something called "Single-Threaded Debug" and "Single-Threaded" which again causes the same thing. Documentation talks something about "Code Generation Options". What Code Generation Options? WTH are they? Documentation specifically warns us not to use /NODEFAULTLIB workaround. (example /NODEFAULTLIB :msvcrt ). Why? How would I cause troubles? what exactly is it? Please explain the last point in the documentation for MFC users. Because I'm going to use MFC later in this project. Explain Why should we do it? What troubles would it cause if I don't. Anything more you'd like to mention? I mean regarding similar errors. I'm very interested in Linker & its problems. So, if there are any similar things you can mentions them or some keywords atleast.

• Emulating CP/M under Linux

  - by gh403

  I need to be able to run a very old piece of software -- the HI-TECH z80 C Compiler for CP/M. It has been released as freeware by HI-TECH. Alas, it only runs on CP/M. After a lot of Googling, I found a page of utilities for UZIX. One of those utilities is a script to abstract away the emulation of a CP/M machine, thus allowing you to use the compiler as you would any other UNIX program. The problem with this script is that it depends on their own CP/M emulator, which unfortunately will not compile on a modern (x64) system. My question: is there a usable CP/M emulator for Linux that could be used in a similar fashion? Specifically, I need to be able to somehow have it access files from the host system, a la DOSBox. I'm willing to rewrite a script (I don't have to re-use the UZIX one); I just need an emulator. Thanks for any help!

• Explicitly instantiating a generic member function of a generic structure

  - by Dennis Zickefoose

  I have a structure with a template parameter, Stream. Within that structure, there is a function with its own template parameter, Type. If I try to force a specific instance of the function to be generated and called, it works fine, if I am in a context where the exact type of the structure is known. If not, I get a compile error. This feels like a situation where I'm missing a typename, but there are no nested types. I suspect I'm missing something fundamental, but I've been staring at this code for so long all I see are redheads, and frankly writing code that uses templates has never been my forte. The following is the simplest example I could come up with that illustrates the issue. #include <iostream> template<typename Stream> struct Printer { Stream& str; Printer(Stream& str_) : str(str_) { } template<typename Type> Stream& Exec(const Type& t) { return str << t << std::endl; } }; template<typename Stream, typename Type> void Test1(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); /****** vvv This is the line the compiler doesn't like vvv ******/ out.Exec<bool>(t); /****** ^^^ That is the line the compiler doesn't like ^^^ ******/ } template<typename Type> void Test2(const Type& t) { Printer<std::ostream> out = Printer<std::ostream>(std::cout); out.Exec<bool>(t); } template<typename Stream, typename Type> void Test3(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); out.Exec(t); } int main() { Test2(5); Test3(std::cout, 5); return 0; } As it is written, gcc-4.4 gives the following: test.cpp: In function 'void Test1(Stream&, const Type&)': test.cpp:22: error: expected primary-expression before 'bool' test.cpp:22: error: expected ';' before 'bool' Test2 and Test3 both compile cleanly, and if I comment out Test1 the program executes, and I get "1 5" as I expect. So it looks like there's nothing wrong with the idea of what I want to do, but I've botched something in the implementation. If anybody could shed some light on what I'm overlooking, it would be greatly appreciated.
