Hi,

I'm building some packages using CentOS 6, and i have a question that i can't get answer for, i think that is a common task in rpm build that will get some info that will help in automate some process.

I need to get a spec file with all macro exanded, so i can extract info of buildrequires, etc..

If you want to know the buildrequries, you can do this to with the SRPM:

rpm -qp --requires <name>.src.rpm

You can also extract the spec file directly with the command and then do things with sed or grep to that file:

rpm2cpio <name>.src.rpm | cpio -i *.spec

You can also see all the macro information for rpm with the command:

rpmbuild --showrc
