  • Eclipse is not importing jar dependencies between two projects in the same workspace

    - by jax
    Here is the situation. I have a java project "LicenseGenerator" in eclipse that depends on commons-codec. I have therefore added the commons-codec jar file to the build path. I have Junit tests and everything is working fine. I have made a different project in the same workspace - which happens to be an Android project - that needs to use my LicenseGenerator classes. I added LicenseGenerator to the "projects" tab in the build path - the classes were recognized and I was able to use them. Everything compiled and ran. However, when the part of the LicenseGenerator that used the commons-codec was called from my Android project I got the following error. Could not find method org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString, referenced from method This basically tells me that the commons-codec was not packaged which the Android project, so I added the commons-codec to the android project as well but the same error appears. how do I fix this?

  • Build config file into executable?

    - by REM
    I am currently working on a little graphics demo (using DirectX) which is primarily based around an HLSL shader I am working on. Using the D3DX10CreateEffectFromFile I am loading (and compiling the shader) at runtime as I find it easier for tweaking. However, once I am done I'd like to do some combination of the following: Pre-compile the shader so the demo starts up faster for the user Bury (compile into the executable) the compiled shader (or maybe just the source if necessary) Primarily, I want to do this because I want the demo to just be one file that can be very easily copied around. One thing I could easily do is just put the source text right into a cpp but that would be very tedious I needed to update it later. Is it possible to do something like this (using Visual Studio, DirectX, HLSL)?

  • If I Design a CPU Can I Get it Realized in Hardware at a Reasonable Cost?

    - by mudge
    I want to design a CPU and possibly memory and other hardware. I could do this with a hardware description language. Once I do this is it possible for me to send my designs to a manufacturer who will realize the design in hardware and send back to me the CPU(s) ? Can it be done at a reasonable cost? I want to design and make my own computer system and actually have it realized in hardware.

  • Faster code with another compiler

    - by Andrei
    I'm using the standard gcc compiler in math software development with C-language. I don't know that much about compilers or compiler options, and I was just wondering, is it possible to make faster executables using another compiler or choosing better options? The default Makefile sets options -ffast-math and -O3 and I think both of them have some impact in the overall calculation time. My software is using memory quite extensively, so I imagine some options related to memory management might do the trick? Any ideas?

  • Directory layout for a Python project with C extension modules

    - by Kamil Kisiel
    We have numerous projects in our organization that are mixed Python/C. Currently we're trying to standardize on a directory layout for our projects and are trying to come up with a convenient scheme. One point of contention is where to put C extension modules in the tree. We're tossing around a couple of options (relative to project root): ./src/package/subpackage/module.c or alongside the python modules in the package tree: ./package/subpackage/module.c or in a src directory in the subpackage: ./package/subpackage/src/module.c One reason for keeping them out of the package directories could be because it will lead to clutter, especially if there are other .c and .h files which aren't themselves modules but still need to be compiled. Also in the "integrated" scheme, what do you do with headers and files that are used by more than one module? Put them in a common top-level directory? I'd be interested to know what other people are using, or if there are any established best practices for this.

  • Standard library function in R for finding the mode?

    - by Nick
    In statistical language R, mean() and median() are standard functions which do what you'd expect. mode() tells you the internal storage mode of the R object, not the value that occurs the most in its argument. But surely there is a standard library function that implements mode for a vector (or list).

  • Why does the CPU window always appear when trying to debug my project after a rebuild in Delphi 2010

    - by James
    Hi, Whenever I rebuild my application and try to step into a break-point the CPU window always appears. From what I understand the CPU window appears when DCU does not match up with the source file, however, in my case the DCU's are defintely being re-compiled and there are no old ones lying around or anything like that. The strange thing here is if I close down the application and re-open the project, place the breakpoint and run it works fine. I can even modify files and just press F9 to run the project and it works fine....it only seems to be when I rebuild the project (via IDE Project menu or the project context menu) that this CPU window never breaks into the source (even though it can find it!). I also noticed in the callstack a unit called Generics is always the top of the stack, never the unit my break point is in, this is no way related to where my break point is. Any ideas?

  • Powerbuilder ressources

    - by afilatun
    I'm recently working in a company where we use PowerBuilder extensively. The only documentation or ressources we have access to is some basic course saying things like "Do A, then B and you'll get C". I was wondering if there is some better crash courses or tutorials for this language on the net or somewhere else which actually explain something instead of simply taking me by the hand.

  • C++ shared libraries

    - by saminny
    Hi, I am trying to get my head around the way shared libraries work in the c++ unix environment. I understand we only need header files and no shared libraries specification when compiling code. But if I want to create an executable or shared library from my compiled files, do I need to specify shared library dependencies (those are dynamic)? And do the paths of shared libraries need to match the path at runtime loading? I am using Linux 2.6.18-164.11.1.el5 #1 SMP x86_64 GNU/Linux I am having a problem where my code is not able to pick up a library at runtime. I have tried setting LD_LIBRARY_PATH and PATH. But at runtime when I run the executable, I get the following error: Error: librc.so: cannot open shared object file: No such file or directory Sam

  • Accessing Erlang business layer via REST

    - by Polyn
    For a college project i'm thinking of implementing the business layer in Erlang and then accessing it via multiple front-ends using REST. I would like to avail of OTP features like distributed applications, etc. My question is how do I expose gen_server calls/casts to other applications? Obviously I could make RPC calls via language specific "bridges" like OTP.net or JInterface, but I want a consistent way to access it like REST.

  • Combining several static archives into a new one

    - by knight666
    I'm making a game engine for mobile devices. I want to compile my code, link it against a few static libraries and then combine my compiled code with those static libraries to form a new static library. However, my Google Fu is abandoning me. Suppose I have static libraries a.a, b.a and c.a and my code. I want to compile all that into awesome.a. How can I do that? I'm using CodeSourcery's arm-none-linux-gnueabi-ar by the way. Thanks in advance.

  • Eclipse javascript character encoding

    - by Bardock
    Hi, I'd like to display some language specific characters from javascript but I can't. My app is a Java webapp and the front end is jQuery. All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly. When I want to display some text hardcoded in to the javascript file it's broken. I'm using Eclipse. In the JSP's header I use: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> I've tried this (charset in the script element) too: <script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script> In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. But when I try this: $.test = function(){ var s = "éééáááuuuu"; alert(s); } I get: éééáááűűűű The strange thing is that: When I try in a separate html file (in the same project), It's working: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type="text/css"> body {background: #c0c0c0;} </style> <script type="text/javascript"> $(document).ready(function(){ var s = "éááuuúúú"; $("#console").text(s); alert(s); }) </script> </head> <body> <div id="console"></div> </body> </html> Even if I DO NOT use any content type and page encoding settings. What is the problem? What shall I do? (I'm using Apache Tomcat integrated in Eclipse) Thanks in advance!

  • How do I determine the cause of Qt's "*** is not a valid Qt plugin" error?

    - by chadjoan
    When I print the value of errorString from my QPluginLoader object, I get this: The file 'C:/pyprojects/test/qsqlpsqld4.dll' is not a valid Qt plugin. I would like to avoid some days worth of doing the time consuming "guess-and-check" methodology that my current internet searches reveal (so far none of them seem relevant anyways). Is there a way for me to get the Qt library itself to tell me why it is refusing to load this plugin? I don't want to guess; I want to know. Context: I am on Windows 7 running Qt 4.8.5 (32-bit, MinGW) and the qsqlpsqld4.dll file is also 32-bit and compiled with MinGW. I am using PySide to interact with Qt.

  • Lib Files and Defines

    - by Paul
    I'm using a couple of external libraries and I'd rather not have to include all their source and header files in my main source directory or in my project file. One option would be to compile the libraries as lib files and link them like that. However I'm not sure the defines get evaluated before or after the lib file gets created (which one is it?). If it's before then obviously I can't just pack them because they might not work properly on different compilers or systems. So if I can't pack the libraries as lib files, is there any way for me to link in the c or cpp source files? Probably not, since they would have to be compiled first, but maybe I'm wrong. Edit: Here's a follow-up question, based on answers. Do you think it'd be too much of a hassle to have a makefile that creates the lib files? I'd still rather not add the sources to my project or in my source directory.

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.

  • Why doesn't Java allow for the creaton of generic arrays?

    - by byte
    There are plenty of questions on stackoverflow from people who have attempted to create an array of generics like so: ArrayList<Foo>[] poo = new ArrayList<Foo>[5]; And the answer of course is that the Java specification doesn't allow you to declare an array of generics. My question however is why ? What is the technical reason underlying this restriction in the java language or java vm? It's a technical curiosity I've always wondered about.
