is there a GCC compiler/linker option to change the name of main? [duplicate]

Answer 1

I'd tend to use different files and make for testing and production builds, but if you did have a file with

int test_main (int argc, char*argv[])

and

int prod_main (int argc, char*argv[])

then the compiler options to select one or the other as the main are -Dtest_main=main and -Dprod_main=main
