Hi there, I got many error messages on FC5 fully updated trying to compile tar packages using "rpmbuild -ta tar_package.tar.gz" command. I notice that rpmbuild was executing "/bin/tar xOvf - Specfile" and "/bin/tar xOvf - <package_name>.spec" commands to extract .spec files from the tar packages but without success. The rpmbuild command always create "/usr/src/redhat/SPECS/tar\:\ Pattern\ matching\ characters\ used\ in\ file\ names.\ Please\," and "tar\:\ You\ must\ specify\ one\ of\ the\ \`-Acdtrux\'\ options" files in /usr/src/redhat/SPECS directory. I solved this problem adding "-" before tar options and "--wildcards" to tar command in build.c file. (see attached patch). Is this problem a rpmbuild bug? There is a way to fix if without patch / recompile rpm packages? These are the steps to reproduce this problem: # wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.18.tar.bz2 # tar -xjvf linux-2.6.18.tar.bz2 -C /usr/src # cd /usr/src/linux-2.6.18 # make oldconfig # make rpm make clean set -e; cd ..; ln -sf /usr/src/linux- 2.6.18 kernel-2.6.18 set -e; cd ..; tar -cz --exclude SCCS --exclude BitKeeper --exclude .svn --exclude CVS --exclude .pc --exclude .hg --exclude .git -f kernel-2.6.18.tar.gz kernel-2.6.18/* set -e; cd ..; rm kernel-2.6.18 set -e; \ /bin/sh /usr/src/linux-2.6.18/scripts/mkversion > /usr/src/linux-2.6.18 /.tmp_version set -e; \ mv -f /usr/src/linux-2.6.18/.tmp_version /usr/src/linux-2.6.18/.version rpmbuild --target i686 -ta ../kernel- 2.6.18.tar.gz Building target platforms: i686 Building for target i686 error: Name field must be present in package: (main package) error: Version field must be present in package: (main package) error: Release field must be present in package: (main package) error: Summary field must be present in package: (main package) error: Group field must be present in package: (main package) error: License field must be present in package: (main package) make[1]: *** [rpm] Error 1 make: *** [rpm] Error 2 ("make rpm" executes "rpmbuild --target i686 -ta ../kernel- 2.6.18.tar.gz") thanks, Márcio
