building tips

When you want to build rpm's make sure you ~/.rpmmacros file is more or less sane:

Example

 %packager       J Doe <johndoe@example.tv>
 %vendor         HomeMade
 %_topdir        /home/jdoe/rpmbuild
 %_tmppath       /home/jdoe/rpmbuild/tmp
 %debug_package  %{nil}

And the correct directories have to exist:

 ${HOME}/rpmbuild/
 ${HOME}/rpmbuild/RPMS
 ${HOME}/rpmbuild/RPMS/i686
 ${HOME}/rpmbuild/RPMS/i586
 ${HOME}/rpmbuild/RPMS/athlon
 ${HOME}/rpmbuild/RPMS/i486
 ${HOME}/rpmbuild/RPMS/i386
 ${HOME}/rpmbuild/RPMS/noarch
 ${HOME}/rpmbuild/tmp
 ${HOME}/rpmbuild/BUILD
 ${HOME}/rpmbuild/SPECS
 ${HOME}/rpmbuild/SRPMS
 ${HOME}/rpmbuild/SOURCES
