I have run into an issue that is unclear on MacPorts. In fink
we often would put placekeepers in a patch such as @FINKPREFIX@
and use the command...
sed 's|@FINKPREFIX@|%p|g' <%{PatchFile} | patch -p1
to replace the @FINKPREFIX@ with the actual fink installation
directory.
How do you handle this situation in MacPorts where you want to
generalize the MacPorts prefix in a Makefile patch for instance
to survive the case of a user installing MacPorts in a non-default
location other than /opt/local?
If you don't want to remember all the zillion files
that your port may need patching, then you _can_ do
override to do something similar in MacPorts as well:
patch {
foreach patch $patchfiles {
system "cd '${workpath}/${distname}' && \
sed -e 's#@@PREFIX@@#${prefix}#g' '${portpath}/$
{filesdir}/${patch}' | patch -p0"
}
}
But that's usually only needed for some really stupid
and unportable ports, like for instance "yum" and such.
(since it loves to hardcode /usr and #!/usr/bin/python)
Someone suggested it should be a "patch" feature, but
nobody bothered implementing it (as far as I know)...
Like: "patch.replace @@PREFIX@@=${prefix}", or somesuch
