This took a while but I am able to build amarok against both ruby 1.9.x and ruby 1.8.x.

One patch updates ConfigureChecks.cmake to determine the ruby version and return the correct location of ruby.h for each version. This patch is mandatory.

The second patch updates http11.c only when the ruby version is greater than 1.8.x.

Note: I perform the same conditional patching with tdebindings. Refer to bug report 597 for the tdebindings patch.

Here is the link to the mandatory ConfigureChecks.cmake patch:

http://humanreadable.nfshost.com/trinity/patches/amarok/amarok-ruby19-cmake.diff

Here is the link to the conditional ruby 1.9.x patch:

http://humanreadable.nfshost.com/trinity/patches/amarok/amarok-ruby19.diff

Here is how I run the patches in my amarok build script:



cat $CWD/amarok-ruby19-cmake.diff | patch -p1 --verbose --no-backup-if-mismatch || exit 1

RUBY_VERSION="`ruby --version | awk '{print $2}'`"
RUBY_VERSION_SHORT="`ruby --version | awk '{print $2}' | awk -F '.' '{print $1$2}'`"
if [ "$RUBY_VERSION_SHORT" -gt "18" ]; then
  echo "==========================================================="
  echo "Ruby version=$RUBY_VERSION: Patching for ruby > 1.8.x."
  echo "==========================================================="
  echo
  cat $CWD/amarok-ruby19.diff | patch -p1 --verbose --no-backup-if-mismatch || exit 1
else
  echo "==========================================================="
  echo "Ruby version=$RUBY_VERSION: Not patching for ruby > 1.8.x."
  echo "==========================================================="
  echo
fi



I run the same test for tdebindings, albeit with different patches.

At this point I have successfully built amarok with all options except RIOKARMA.

After somebody tests the patches, I will push the mandatory cmake patch. I can't push the conditional patch because many people still use ruby 1.8. I don't know how to merge such a conditional patch anyway.
