gcc/gdb: How to embed absolute path to source file in debug information?

i am just wondering if i can tell gcc to embed the absolute path to a source file in the debug information, even if i call gcc like

gcc -g ../src/somecode.c -o ../bin/somecode.o

as i see it atm, gcc just stores what you provide, so if you provide a relative path, at the end, gdb only knows the relative path as well.

is there a way to bypass that without using absolute paths while compiling? like: let gcc lookup the complete path?

thanks in advance rTi

Solution 
  • gcc -fdebug-prefix-map=..=$(readlink -f ..)
