  • Symbol from C file is not being added even though the MakeFile includes its object file

    3 février 2021, par Mahfujur Rahman

    I'm trying to build libavformat with this MAKEFILE. Although the makefile includes avio.o file in its build instruction but it doesn't add any symbol for the functions that are declared on the header file url.h. Source folder which includes the avio.c, avio.h and url.h files can be found HERE.

    


    The nm command for avio.o returns

    


    nm: avio.o: File format not recognized

    


    file command on avio.o shows the following output

    


    avio.o: LLVM IR bitcode


    


    I have checked the nm command on the generated libavformat.so and did not find any symbols for the functions declared on the url.h file

    


    I have been stuck on this for two days. Could not figure out how to solve this problem !

    I've only modified commands.
