I found out how to do it: rpath specifies where the provided libraries are located. This folder should contain: libc.so.6, libdl.so.2, libgcc_s.so.1 and maybe more. Check with strace to find out which libraries your binary file uses. ld.so is the provided linker gcc -Xlinker -rpath=/default/path/to/libraries -Xlinker -I/default/path/to/libraries/ld.so program.c
Static libraries should never include other static libraries (or third party code in general). A static library is just a bundle of .o files glued together. So if you have multiple copies of the same information, it’s going to blow up. Each static library should just have its own code in it. The final application … Read more
A priori, no. The safest solution is to assume that all of the compiler options are identical, except when the compiler specifically documents that the option doesn’t affect binary compatibility. (Documentation which is sorely lacking in most compilers.) In practice, in the lack of documentation, it seems a safe bet that options which control warnings … Read more
The library that you are using needs to be placed after the files that use it when you are using it from the command line. So place -lm on after your C files on the command line. Reference
One thing that I’ve used in the past (when global variables were in vogue): var.h file: … #ifdef DEFINE_GLOBALS #define EXTERN #else #define EXTERN extern #endif EXTERN int global1; EXTERN int global2; … Then in one .c file (usually the one containing main()): #define DEFINE_GLOBALS #include “var.h” The rest of the source files just include … Read more
Add the wsock32.lib in the text field. Project Properties -> Linker -> Input -> Additional Dependencies. When you click in the field, you get a … button. Click on this button and add one library name per line. Alternatively you can write the names in the field. Separate all entries with space characters. You can … Read more
Check out Building Objective-C static libraries with categories: Objective-C does not define linker symbols for each function (or method, in Objective-C) – instead, linker symbols are only generated for each class. If you extend a pre-existing class with categories, the linker does not know to associate the object code of the core class implementation and … Read more
when you are linking, the order of your libraries and source files makes a difference. for example for your case, g++ -I/usr/local/cuda/include -L/usr/lib/nvidia-current -lOpenCL opencl.cpp functions defined in the OpenCL library might not be loaded, since there nothing before them asking for a look-up. however if you use, g++ opencl.cpp -I/usr/local/cuda/include -L/usr/lib/nvidia-current -lOpenCL then any … Read more
Sure ! (In the following, I assume that you already know how to deal with cimport and the interactions between .pxd and .pyx. If this is not completely the case, just ask and I will develop that part as well) The sample (grabbed from a C++ project of mine, but a C project would work … Read more
In the case of an import library for a DLL, the .lib file does not contain any actual code at all. It basically contains just a list of the functions in the associated DLL — enough for the linker to embed a reference to that DLL into something linked with the library, but not much … Read more
