Adding patches in a SPEC

[Eric "Sparks" Christensen]

I've never had to add a patch to a SPEC file before and I can't seem
to make it work.

The patch is to make a modification to the Makefile.  I created the
patch (diff -u) and put that in my SOURCES directory.  I included the
Patch0: line and then called the patch in %prep using %patch0 (no
switches).  When I run rpmbuild I get the following:

[user at system rpmbuild]$ rpmbuild -ba SPECS/gpredict.spec
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.ILyyD6
+ umask 022
+ cd /home/user/rpmbuild/BUILD
+ LANG=C
+ export LANG
+ unset DISPLAY
+ cd /home/user/rpmbuild/BUILD
+ rm -rf gpredict-1.2
+ /usr/bin/gzip -dc /home/user/rpmbuild/SOURCES/gpredict-1.2.tar.gz
+ /bin/tar -xf -
+ STATUS=0
+ '[' 0 -ne 0 ']'
+ cd gpredict-1.2
+ /bin/chmod -Rf a+rX,u+w,g-w,o-w .
+ echo 'Patch #0 (gpredict-1.2-DSO.patch):'
Patch #0 (gpredict-1.2-DSO.patch):
+ /bin/cat /home/user/rpmbuild/SOURCES/gpredict-1.2-DSO.patch
+ /usr/bin/patch -s -p0 --fuzz=0
The text leading up to this was:
--------------------------
|--- Makefile   2010-11-15 20:07:20.676418835 -0500
|+++ Makefile   2010-11-15 21:35:53.803407014 -0500

File to patch:


It appears to not find Makefile.  Most likely I'm just failing to do
something correctly here.  Can someone point me in the proper
direction?

Thanks,
Eric
