Compile multiple C source fles into a unique object file

Question

I have some C source files and I am using gcc. I basically want to compile all of them and create one single object file. When I try:

gcc -c src         


        

Answer 1

To combine multiple source files into a single object file (at least since gcc 4.1), use the compiler/linker option --combine

(edit) later replaced with the compiler option -flto, with linking automatic depending on the compilation state: Requirements to use flto
