shared-libraries

Problem On MacOS, I get linking problems at runtime for a CMake project that depends on dynamically linked resources – but only after installing the project! The problem does not occur when I only build the binary without installing it. $ ./testapp Hello world! $ $INSTALLDIR/testapp dyld: Library not loaded: @rpath/libvtkDomainsChemistryOpenGL2-7.1.1.dylib Referenced from: /Users/normanius/workspace/installdir/testapp Reason: image not found [1] 76964 trace trap /Users/normanius/workspace/installdir/testapp Minimum example I am able to reproduce the problem in a minimal setup consisting of

I have developed an application that has Qt shared library and Qt application. Qt shared library exports a single class with few signals in it. I have made use of Q_DECL_EXPORT / Q_DECL_IMPORT macros for this. Right now the communication between the dll and application is through Qt signals and slots and that needs the application to be developed using QObject. Now I was asked to make Qt shared library as an ideal DLL where Client application doesn't depend on Qt framework. I saw the following post but Using a Qt-based DLL in a non-Qt application but not sure if that is the best approach.

I am building a shared library in C that is dynamically loaded by a program that I do not have source access to. The target platform is a 64-bit Linux platform and we're using gcc to build. I was able to build a reproduction of the issue in ~100 lines, but it's still a bit to read. Hopefully it's illustrative. The core issue is I have two non-static functions ( bar and baz ) defined in my shared library. Both need to be non-static as we expect the caller to be able to dlsym them. Additionally, baz calls bar . The program that is using my library also has a function named bar , which wouldn't

I have to upload about 30M for my app since it uses a lot of libraries, log, web engine and so on. I think there should be a way to share these libs on glassfish, but I failed to figure it out. I tried to put them in domain/lib/ext but does not work. So where should I store these libs and how should I refer to them? thank you. Why domaindir/lib/ext does not work? from glassfish manual: Optional packages are packages of Java classes and associated native code that application developers can use to extend the functionality of the core platform. To use the Java optional package mechanism, copy

I'd like to build both static and shared libraries in a project. I know that shared libraries need to be be created from objects compiled with -fpic to get Position Independent Code while the static library doesn't need this. This is all fine and I can create either a shared or static library. I wouldn't want to compile my source twice to get the different object files, so how is this usually done? I read how to get a shared library based on a static one . However, the example shows the static library being built with -fpic. Is this the way to go? Are there things to be aware of with this? Is

I am trying to use a widget library called GLV for an application I am developing. I am running Linux Mint 17. I installed all the libraries and I have succeeded in building the GLV library, but when I try to running one of samples that was built I get this shared library error. Inconsistency detected by ld.so: dl-version.c: 224: _dl_check_map_versions: Assertion `needed != ((void *)0)' failed! Can anyone help me find out where the inconsistency in the shared library is coming from? More information In the README file it says GLV requires only OpenGL, GLU, and GLEW (Linux only). There are no
