shared symbols while linking in GCC

venkee · 10-03-2018, 03:22 AM

is there a way to specify the shared symbols across libraries through a text file to GCC linker?? instead of specifying their address manually in the linker script??

Welcome to LQ

Re your question: Are you a new, or experienced coder? I presume it's Library symbols you mean

Normally, gcc compiles the code, and ld (part of glibc) is employed as necessary to link in the libraries. Libraries generally hold much used modules or subroutines which save a coder from reinventing the wheel.

'info ld' will give you a truly sickening amount of information on how it's done. Most of us are satisfied not to look under the hood as long as it keeps happening correctly.

I've never heard of using a text file for that. The symbols really have to come from the libs.

Symbols should be resolved automatically by GCC without resorting to linker scripts unless you're mixing and matching object files between compilers or assemblers.

If this is a C++ problem, I'd have no idea, however.
