gcc option -E use.

niverson · 10-11-2004, 02:59 PM

Does anyone have a pointer to using gcc's -E option? This option should produce a target file that has gone thorough only the C preprocessor. I would like to look at some macroized state table that are built up by the preprocessor. I tried 'gcc -E file.c -o file.c'

I read the gcc documentation for the -E option but it didn't make sense to me?

Thanks,
Nate

gcc -E file.c -o file.c

eh. The two file.c's are a mistake I hope.

Try gcc -E file.c -o file.i

or just skip the -o
you dont need it, gcc will stick it in file.i anyway

Code:

echo '#include <string.h>'  | gcc -E -
