check gcc -v within script

jong357 · 01-20-2006, 10:10 AM

Greets all. I'm making a gcc build script and I would like to do a gcc -v and grep for the version number so I know whether or not a bootstrap needs to happen. What's the best way to go about this? I can't even seem to output gcc -v to a text file to grep from that. I'm sure it can all be done without a text file in the first place.

Any help would be most welcome. Thanks much.

hi,

so, IIUC, you need the version of the compiler you're gonna use to compile gcc.
in that case you can use " gcc -dumpversion ".

Too funny. Thanks egag... For some reason, I was under the impression that -dumpversion would spit your spec file out. Guess I was thinking of -dumpspecs

Thanks again. That's exactally what I wanted with no grep involved. Makes life easy. Next time I'll try to ask gcc for --help instead of you..
