Question

In creating a static object is it possible to rename the symbols at compile time (without changing the code) in a cross platform way? I have recently had objcopy recommended, but linux is not the only target platform it must also work on a mac. I am compiling using gcc, so I was hoping that there was a gcc option of some sort.

I have heard about .def files, but this may have been misleading as the information about them that I have found seems to be for windows.

Edit:
I’m trying to change the name of C and Fortran functions, specifically pre-pending them with the word “wrap” in order to avoid symbol conflicts at link time.

is it possible to rename the symbols at compile time

You might be able to achieve it with preprocessor:

gcc -c foo.c -Dfoo=foo_renamed
