  • How to link .lib library in linux

    - by giga
    I'm pretty new to c programming and want to port a windows c application to linux. My code uses a .lib file va_g729.lib - is it possible to use the same library in Linux and compile it with gcc? All my .c and .h files along with the one .lib files are in the same directory. What I'm doing now is executing this command in the directory: gcc *.c -lm and I get following errors: lbcodec2.c:(.text+0xa6b): undefined reference to `va_g729a_init_encoder' lbcodec2.c:(.text+0xa83): undefined reference to `va_g729a_encoder' collect2: error: ld returned 1 exit status Is it possible to link the .lib file and compile with gcc? Thanks.

  • OS X Terminal: Meta key + alt functionality at the same time

    - by abababa22
    Is there a way to use "alt/option" key as a meta key but still be able to use the key to make some characters which need it? For example in my local keyboard layout: @ is alt-2 \ is alt-shift-7 | is alt-7 etc. So if I set alt as meta key, I can't make those characters. On the other hand using "press esc, release esc, press a key" to make meta key sequences makes my hands hurt. Any emacs users with international keyboards who have solved this, please give any tips you might have! :) edit: It appears that I can set alt as meta key and then add these kind of settings in inputrc: "\e2": "@" This works in bash shell but it still won't work with emacs though, so no good.

  • Spotlight query to search for all archives and ISO files that their names do not end in bin

    - by Bytecode Ninja
    The following Spotlight query, correctly returns all archive and ISO files on my system: kind:iso OR kind:archive However, Spotlight treats .bin files as archives too and returns .bin files in the results as well. How can I modify the above query and exclude files that end in bin from the result? I tried the following query but it is not working: (kind:iso OR kind:archive) AND NOT name:*bin Thanks in advance.

  • Obj C - how to customise the interval between slides with IKSlideShow

    - by doraemon
    I'm very new to Objective-C and Cocoa but I've made a simple app which uses ImageKit to present a slideshow using the IKSlideShow class. However I've got a bit stuck with something I thought would be simple. I want to increase the time photos are displayed on screen when the slideshow is playing, but I can't see how to do it effectively. The IKSlideshowDatasource protocol lets you do stuff when "slideshowDidChangeCurrentIndex" which seems to be the best place to do this - however I've tried putting various delays in here such as: while ( functionShouldPause ) { [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:20]]; functionShouldPause=NO; } However they prevent the user for manually moving on the slides, or leaving the slideshow. Very grateful for any suggestions. Thanks!

  • How to determine, upon launch, whether the app crashed the last time it quit?

    - by enchilada
    One of the crash reporter frameworks I've found does it like this: If there exist crash reports in the ~/Library/Logs/CrashReporter folder for the app, it determines that a crash occurred before. Then it allows the user to send the developer the crash log. And the finally, it deletes those logs. It is this deletion that is bothering me. It's not acceptable to me. Maybe the user wants to look at those logs later. It is simply rude to the user to just delete his crash logs. So I'm looking for a better way to determine the crash. It doesn't really work to store the last read crash logs in the user defaults or the user data, because that would mean that if the user deletes the data and defaults (which he has a right to do whenever he or she wishes), and then launches the app, it will be detected as crashed the last time it was quit. So this doesn't work. Any ideas?

  • when to use "willChangeValueForKey" and "didChangeValueForKey"?

    - by Frost Li
    I saw these lines in a demo project, but I couldn't understand why it did that. [self willChangeValueForKey:@"names"]; [self didChangeValueForKey:@"names"]; It called didChangeValueForKey immediately after willChangeeValueForKey. Does it make any sense? Furthermore, when should be the right time to call this two methods? Thanks a lot!! :)

    Hello, gcc 4.4.4 c89 Visual Studio VC++ 2008 I am writing a cross platform client server application. It will run on both linux and windows. However, I am just wondering what I have done for closing the sockets is correct. I close the file descriptor. However, if there is a problem with closing it. What is the best way to handle this. Maybe some data is still being sent or received?

  • How to get at TCP RTT on Windows (Linux TCP_INFO) as an user

    - by FredAlkin
    I am porting a streaming TCP app from Linux to Windows. The app streams real-time audio data using a preexisting TCP protocol (so switching to UDP isn't an option). Further, I wish to avoid being "part of the problem" and requiring Administrator rights. The Linux code uses getsockopt(... ,SOL_TCP, TCP_INFO, ..) to get the RTT (round trip time) information from the TCP connection. The application level uses this to throttle the amount of data sent over the connection (apparently to balance quality with latency). Is there an equivalent to TCP_INFO on WIndows? (google tells me that Win2K and later supports "TCP Timestamps" which would provide this information, but I've yet to find a way to get at it. Thanks in advance.

  • JQUERY AJAX works on linux, but not on windows box

    - by awebbdesign
    I have a strange issue where the code works fine locally and on a linux server but not on a windows server... Works fine on: bijoudancewear.co.uk/mapper/ Doesn't work on: faringdongolfcourse.co.uk/mapper/ After clicking on map... If you click on 'Department Stores, fashion & Accessories' (2nd from bottom) it loads the appropriate data on the linux box but not on Windows. Also works fine locally on my mac, there is no ASP or PHP, this is good old fashioned html and jquery. Any pointers would be great.

  • Eclipse 3.5 (Cocoa) slowing down irregularly after some time

    - by chris_l
    Hi, I'd like to hear, if anyone else encounters the same problems, and doesn't use Google's GWT (2.0) plugins: Sometimes, my Eclipse 3.5 (Cocoa) slows down after some time of usage (=30 minutes), so that things like maximizing an editor or moving the splitters becomes unbearably slow (reacting only after several seconds). After an Eclipse restart, everything's fine again. I'm not running low on memory (neither free RAM, nor memory available to Eclipse - Heap/Stack/PermGenSpace), and my system specs are not too bad. I know exactly one other person so far, who sees the same problem - but he also uses the GWT plugins. Since these issues appear irregularly, they're hard to track. Before creating an issue on the GWT bug tracker, I'd like to find out, if this also happens for somebody without Google's plugins. Thanks, Chris Edit: I'm running Snow Leopard 10.6.2

  • No such file or directory python in linux only (coming from windows)

    - by user1804633
    I have the same exact directory structure within a folder in Windows & in Linux (Debian) - where the script is along the static + dataoutput folders How come the following code works fine in Windows, but gives a no such file or directory path error in linux? @app.route('/_getdataoutputfilelisting') def getdataoutputfilelisting(): listoffilesindataouput = getfiles('static/dataoutput') return jsonify(listoffiles = listoffilesindataouput) def getfiles(dirpath): a = [s for s in os.listdir(dirpath) if os.path.isfile(os.path.join(dirpath, s))] a.sort(key=lambda s: os.path.getmtime(os.path.join(dirpath, s))) a.reverse() return a Is there a way to make it universal such that it works in both OSs? Thanks

  • Create Zip File In Windows and Extract Zip File In Linux

    - by Yan Cheng CHEOK
    I had created a zip file (together with directory) under Windows as follow : package sandbox; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; /** * * @author yan-cheng.cheok */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // These are the files to include in the ZIP file String[] filenames = new String[]{"MyDirectory" + File.separator + "MyFile.txt"}; // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // Create the ZIP file String outFilename = "outfile.zip"; ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename)); // Compress the files for (int i=0; i<filenames.length; i++) { FileInputStream in = new FileInputStream(filenames[i]); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filenames[i])); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); } catch (IOException e) { e.printStackTrace(); } } } The newly created zip file can be extracted without problem under Windows, by using http://www.exampledepot.com/egs/java.util.zip/GetZip.html However, I realize if I extract the newly created zip file under Linux, using http://www.exampledepot.com/egs/java.util.zip/GetZip.html, I will get a file named "MyDirectory\MyFile.txt" instead of MyFile.txt being placed under folder MyDirectory. I try to solve the problem by changing the zip file creation code to String[] filenames = new String[]{"MyDirectory" + "/" + "MyFile.txt"}; But, is this an eligible solution, by hard-coded the seperator? Will it work under Mac OS? (I do not have a Mac to try out)

  • Issue in setting up VPN connection (IKEv1) using android (ICS vpn client) with Strongswan 4.5.0 server

    - by Kushagra Bhatnagar
    I am facing issues in setting up VPN connection(IKEv1) using android (ICS vpn client) and Strongswan 4.5.0 server. Below is the set up: Strongswan server is running on ubuntu linux machine which is connected to some wifi hotspot. Using the steps in this guide link, I generated CA, server and client certificate. Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on android device. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212, android device eth0 interface ip address: 192.168.43.62; Android device is also attached with the same wifi hotspot. On the Android device, I uses IPsec Xauth RSA option for setting up VPN authentication configuration. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.62 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add      With the above configurations when I enable VPN on android device, VPN connection is not successful and it gets timed out in Authentication phase. I ran wireshark on both the android device and strongswan server, from the tcpdump below are the observations. Initially Identity Protection (Main mode) exchanges happens between device and server and all are successful. After all successful Identity Protection (Main mode) exchanges server is sending Transaction (Config mode) to device. In reply android device is sending Informational message instead of Transaction (Config mode) message. Further server is keep on sending Transaction (Config mode) message and device is again sending Identity Protection (Main mode) messages. Finally timeout happens and connection fails. I also capture Strongswan server logs and below are the snippets from the server logs which also verifies the same(described above).

  • Reserve RAM in C

    - by petersmith221
    Hi I need ideas on how to write a C program that reserve a specified amount of MB RAM until a key [ex. the any key] is pressed on a Linux 2.6 32 bit system. * /.eat_ram.out 200 # If free -m is execute at this time, it should report 200 MB more in the used section, than before running the program. [Any key is pressed] # Now all the reserved RAM should be released and the program exits. * It is the core functionality of the program [reserving the RAM] i do not know how to do, getting arguments from the commandline, printing [Any key is pressed] and so on is not a problem from me. Any ideas on how to do this?
