[LLVMdev] How to get the symbols from a .so file?

[Dimitar Dobrev]

    Hello Alexey,

    I did so a little after sending the e-mail (the tip is good nevertheless). I copied the relevant path in code and it worked fine. Thank you for your reply.

Hi Dimitar,

This is pretty weird that createObjectFile() doesn't work. What errors do you observe? You may take a look at a various LLVM commandline tools that walk the symbol table of the file for inspiration.
See tools/llvm-nm/llvm-nm.cpp for example. (it uses createBinary()) function.

 Apparently I need to use different code to parse a shared object but I have little idea what. Any help will be appreciated.
