Creating Patch files ==================== (1) Edit the file to be patched in the same directory as the original file keeping it as *.bak or similiar. The location must be in the rpm build area relativ to RPM_BUILD_DIR (where the sources are unpacked) because the patch is performed during the prep step. (2) use diff -Naur [oldFileVersion] [newFileVersion] > File.patch (3) Copy the *.patch file into distribution source directory (usually somethink like ~/rpm/SOURCE) and keep it in this svn repository directory (4) Add a line "Patchx File.Patch to the spec file.
