> My need is quite simple: I have an executable who needs dlopen. To test it, I planned to write a bash script that would have done "./exe /path/to/lib.so" on linux (debian, ...) OR "./exe /path/to/lib.dylib" on osx. To replace correctly so/dylib in the bash script I need to know the architecture. Any idea how to do this ?
