SOLVED. See below for the corrections (labeled FIXED). I'm having trouble creating a shared library using gcc. I created a little sample project that closely mirrors the structure of the actual project I'm working on. I've made it available as a tar.gz archive here: http://209.59.216.197/libtest.tar.gz FIXED: I've made the fixed v...
I have created a communication library which is linked statically into several different applications. The library provides support for communication via different kinds of hardware. Some of the hardware is supported from the vendor via a shared library. On systems without those kinds of hardware, the shared library is not available. Pr...
I'm dynamically loading (whith dlopen()) a shared object (named libprofile1.so) from main. In libprofile1.so I have defined factory function CreateProfile and class Profile. CreateProfile function creates an instance of Profile class and returns a pointer to it. Class Profile has a method pMethod. In main, after loading libprofile...
Greetings all, I use MinGW,QT and CMake for my project. As shown in the figure, my project has two modules. libRinzoCore.DLL - a shared library which define some abstract classes and interfaces and some core functionality of the application.This module is used to implement dynamic Plugins (which are also shared libraries which auto...
I have a Cocoa application as XCode project that has several supplementary bits of functionality as dylib targets. When XCode builds the project, it places all the build outputs in a single folder: The .app bundle and the dylib files. And when executed from the XCode debugger, the .app launches. I can't however launch the application f...
Considering the following archetypal Boost.Python module, which brings a class "D" from a separate C++ header file. /* file: a/b.cpp */ BOOST_PYTHON_MODULE(c) { class_<d>("D") } When I compile this to a shared library, I'm confused how I can expose it to Python. What should I call the library? a.so? liba.so? b.so? libb.so? Where...
When ld-linux resolves a symbol it searches through the shared libraries in a particular order and stops when it finds a shared library with a matching symbol. What determines the order it searches through the libraries? Does it make a difference if the unresolved symbol is in the main program or in another shared library? How could I ...
My application dynamically loads liba.so (with dlopen). liba.so uses libb.so so I want to link liba.so against libb.so. How to do this in Linux? Thanks in advance. ...
Can a static libary *.a in Linux be dynamically loaded at runtime? I've read here that ...both static and shared libraries can be used as dynamically loaded libraries. How to dynamically load static library? ...
Hi, I'm building a shared library with f-no-rtti. Internally, this library throws std:invalid_argument and catches std::exception, but the catch clause is never entered. The following code reproduces the problem (g++ 4.2, Mac OS X 10.6): // library.cpp: exports f(), compiled with -fno-rtti #include <stdexcept> #include <iostream> exte...
I'm having trouble with gdb and loading debugging information from shared libraries. The error I get when running from within gdb is: >>run Error while mapping shared library sections: libhmmm.so: Success. .... .... >>break container_main Error cannot access memory at 0x9f18 The shared library in question exists and is located in the...
I want to share my code libraries between multiple PHP projects. I am using SVN (unfortunately). What other options are there to share code besides using 1) svn:externals or 2) a shared repository checkout + paths in config files? My objections to svn:externals are: 1) Mercurial does not have this, and I prefer that; and 2) it is easy ...
I have a Makefile for linux that I am porting over to Darwin. The makefile takes a bunch of .o files and links them together into a .so shared object. Okay, so I figured (am I wrong about this?) that the best analog for this in Darwin is the dylib. So I changed the -shared flag to -dynamiclib. Now the code that I am linking together ...
I'm a relative noob to installing libraries. My system currently has an older version of the ICU library (3.8) and I want to go the latest (4.4). Following the steps in the ICU readme.html, everything goes fine (echo $? produces all 0 for every step). And I see the libary was installed to /usr/local/lib. However the current version of t...
I belong to a .NET shop using TFS. In the last year or so we've been trying to share and between our teams (some local, some in a completely different region). Up until now, we've included shared code as project references. As the dependency on the shared code grows, we're getting into more and more problems (people modifying code th...
Hello all, I have the following problem : several object files a1.o, a2.o, a3.o, ... an archive libxxxx.a. The archive libxxxx.a only contains object files : b1.o, b2.o etc... I would like to create a shared library (.so) from all the object files. Problem : If I use : g++ -shared libxxxx.a a1.o a2.o ... -o libnew.so g++ does un...
Hello, I'm trying to build a dynamic library on Linux using qmake. Here is my .pro file: TEMPLATE = lib TARGET = sqxUiBase QT += core gui CONFIG += dll INCLUDEPATH += ../../public/include DEPENDPATH += .

Hi all, I work in a small developing team with 3 developers and none of us are really 'uber elite programmers' but we get by pretty well for our company. One thing that has been constantly recurring is we keep using the same resources in multiple projects. One example being the fckeditor control, however it stinks to constantly add this...
I have a normal class library. Recently, I localized this class library. I also have another Silverlight class library, Which is basically a linked file project <Link>Reports\Reports.cs</Link> In that, I have included the same resx file as link reference as I done for other files. While running, it throws the following exception. ...
I wand to implement in CMake a functionality that would enable the installation of a single binary/target through a make install-TARGET command. This is fairly straightforward to do with a custom target. However, when the target binary in question is linked dynamically against other libs of the project (BUILD_SHARED_LIBS=ON), I need to i...
