[eric]

Dear linux programers:

at /usr/src/RPM/SPECS

I have gcc.spec
then I tried rpm -bp gcc.spec
it not work just show how rpm 's option

also in my /usr/src/RPM/SOURCES
I had 
gcc-2.95.2-2.95.3.diff.bz2*

is it matter?
I also did, rpm -bp goo-2.95.spec
same thing, not work-I check my SOURCE and BUILD directory no .c or .h
files.

need help to get source code out
