Re: macro to print filename

From what I understood, Ratheesh wanted a compile time solution.

My workaround will be to go for  a Makefile based compilation.
1)  "gcc -E yourfile.c"  will preprocess only. so __FILE__ will be expanded .

output file will be yourfile.c (with macro expanded)

2) then run your custom tool/bash script to trim the filepath to filename.
use awk tool maybe.

3) Do the final compile using Gcc
