    c osx linker ld ar
    I am having problems with the linker when porting a C library from Linux (Ubuntu) to OS X. The C code is auto-generated from Matlab, so ideally I don’t want to change the code itself.The problem seems to be in a C file which contains ONLY uninitialised variable declarations, which are then EXTERNed by other C files to implement the Matlab algorithms. The OS X linker is apparently unable to recognise symbols from this file. The same source code works fine on Linux, so I want to understand how the OS X linker is behaving

    Below is the description of the issue. I marked it all as a code to avoid the implicit formatting that StackOverflow does. That is pretty annoying to have to deal with the Wiki-like markup language when I know exactly myself how I want to format my question.I am dealing with a weird toolchain issue on Macos. Here is what is going on :$ cat

    I am attempting to link a thin archive that combines two archive libraries to a C program. I constructed two simple hello world functions and built an archive with the commands:ar rcs lib1.a lib1.o ar rcs lib2.a lib2.oThe two archives are then merged using a thin-archive:ar rcsT all_lib.a lib1.a lib2.aand then compiled with gcc:gcc main.o all_lib.a -o helloI end up with a e

    linker static-libraries ar .a
    If one builds static libraries in one’s build scripts and one wants to use those static libraries in linking the final executable, the order one mentions the .a files is important:g++ main.o hw.a gui.a -o executableIf gui.a uses something defined in hw.a the link will fail, because at the time hw.a is processed, the linker doesn’t yet know that the definition is needed later, and doesn’t include it in the being.generated executable. Manually fiddling around with the linke

    c linker make static-libraries ar
    I’m working on a quite large and messy project that I haven’t really got time to clean up and I’ve been tasked with providing an API for it. What I’m trying to do is wrapping all the ugly stuff up in a single static library and then provide it with a single head

    First of all, I have all sources for my libraries. (The other topics on the matter I found on SO were not quite about the same thing) The only problem is that the c

    I have a C project using several object files that needs to be linked in a specific order to find all needed symbols.For example this command works fine (lib2.o depends on lib1.o etc.)gcc -o my_app main.o lib1.o lib2.o lib3.o -lm

    I have written some code in Lib_file.h and Lib_file.cpp. I wish to convert this code to a static library. I am able to compile the code (using the command g++ -I -o Lib_file.o Lib_file.cpp)to get Lib_file.o. I am also able to add it to an archive using the ar rv
