How Can I know what functions are there in an executable file?

Question

I have a binary file in Linux, and I want to know what functions has it been compiled with.

My project consists on several object files, each one containing different functions. And sometimes I dont know which ones I compiled the executable with. How can I know?

I am compiling with a toolchain in different architectures (arm, mips...).

Thanks.

You can use dumpbin on Windows.
