MacPorts, formerly known as DarwinPorts, is a variant of the BSD ports system for Darwin and Mac OS X.
This page describes how to upgrade a port in MacPorts to a later version of the respective software.
In this example, we update the portfile for gnustep-base. This is just an example.
To find out the URL where the upstream source is located, do:
port cat gnustep-base
Check whether a newer version is available at that download location and download it, in this case gnustep-base-1.16.3.tar.gz
Calculate the md5 checksum of the upstream source with
MD5 (gnustep-base-1.16.3.tar.gz) = 32ae302922a0a6e14c7008a105014bba
Copy the portfile first so that we can create a patch later:
cp $(port file gnustep-base) $(port file gnustep-base).orig
port edit gnustep-base
Change version to 1.16.3
Change md5 to the value calculated before
diff -u $(port file gnustep-base).orig $(port file gnustep-base) > gnustep-base.patch
Now build it with
port rpm gnustep-base
In order to activate the new version so that it is used when builting additional software, you need to do in addition:
port archive gnustep-base
port upgrade -n gnustep-base
Finally, check that your activated version is really the new one with
port installed gnustep-base
Search whether a ticket already exists, if not submit a new one with the patch attached.
