[Gpg4win-devel] how to update a single package in the build tree

[Marcus Brinkmann]

Hi,

here is a nifty trick how to update only a single package in the build
tree.  You have to use --enable-maintainer-mode with configure, though.

Preparation:

$ cd src
$ make clean-PACKAGE  # For example, clean-gpgex

Update the packages in packages/ and then in the top-level directory:

$ touch configure.ac
$ make

Note: Regenerating configure is a bit crude, but works.  If you don't
want to do that, or if you don't use --enable-maintainer-mode, the
following might also work:

$ ./config.status --recheck
$ ./config.status
$ make

That's it.

Note: You might need to do a make clean-PACKAGE for some packages
which depend on the updated packages.  There is currently no
automation for that.  Use your judgement (or wait for problems :). 

Note: It is important to first do the make clean-PACKAGE, then rerun
configure, because with the version numbers the directory names
change, too, and the clean will not complete properly otherwise.

Thanks,
Marcus
