Hi --
Attached is a preliminary autoconf script for Ion. Hopefully this will
persuade Tuomo that we can have both the existing system.mk and the autoconf
system peacefully co-existing side-by-side.
The script generates a file called acsystem.mk from the attached
acsystem.mk.in, which is an equivalent of system.mk. automake isn't used at
all.
The script is not finished yet. It works, but needs to be integrated with
Ion better. Currently you need to overwrite system.mk with acsystem.mk.
Ideally, I would like an automatic system to include acsystem.mk if it
exists, otherwise use system.mk.
To use it:
# copy the attached files to your ion directory, then
autoconf
./configure [--enable-xinerama] [--enable-xft] [--enable-debug]
mv system.mk system.mk.dist # move old system.mk out of the way
ln -s system.mk acsystem.mk
To do (at least):
1) Proper POSIX flags for libtu.
2) Check for some tools -- ar, install, ln -s, strip
3) Better Xft support?
Some of the above will require _minor_ changes to the existing Makefiles.
Comments?
If all is OK, I will submit a patch that includes the attached files and
patches the existing Makefiles where needed.
Tom
