If you want to build a better build system, please go ahead and do
it. Just don't break anything in the process since thousands of
people rely on it. Please do not experiment on my code since trivial
changes can cause problems which take hours to fix. I already
experienced this with the addition of pd-devel to the Pd-extended
build system. I had to spend hours debugging the changes in order to
get Pd-extended building again. That is also very annoying at the
least.
The simple changes that you propose seem simple on the face, but have
the possibility to wreak major havoc. If you want to build another
build system, then you should do what I did when building Pd-
extended: I left everything in place without touching it and built
the Pd-extended stuff alongside the existing build.
But yet again, it seems to me a massive waste of time to build Yet
Another Build System. How about instead making the existing one
better? For example, the Pd-extended build system would be much more
flexible if there was a ./configure interface for it. I think we
should extend pd/src/configure.in to create a config.h and have
everything build against that.

Hello all,
hi.
i am redirecting this to pd-dev, since i hope this mail will lead
to some further dev-specific discussion and hopefully to some
usable build system.
Has anyone else had a problem trying to compile an external from
the CVS source? I just checked out the externals dir from CVS, and
wanted to compile the latest [hid], so after reading the README in
the hid directory, I typed:
>make INCLUDE=/usr/lib/pd/src PDEXECUTABLE=/usr/bin/pd
..and got the following:
--paste--
[...]
--end paste--
Why would the build want a /sigpack, and /zexy directory? And am I
missing a Makefile.buildlayout file?
to compile hid (and i guess, any of hans's externals) you need the
entire pd-cvs (at the very least you need the "packages" module)
downloaded from sourceforge.
i agree that this is _very annoying_ at the least.
my solution to compile something as simple as [folder_list] was to
NOT use hcs's build system at all (i really just wanted to have to
download not more than 1MB to get this single object), but instead
compile the object with:
> gcc -g -O2 -I. -DPD -fPIC -export_dynamic -shared -o
folder_list.o -c folder_list.c
> gcc -export_dynamic -shared -o folder_list.pd_linux folder_list.o
-lm -lc
you might try something similar with hid, although things are a bit
more complicated here.
that's basically the answer to your question, the rest is what i
draw as a conclusion:
SO:
i see the need for a "grand unified build system" for things like
pd-extended. but i am not totally sure, whether everything should
be sacrificed to pd-extended.
naturally, hans has the right to do anything with his code,
including forcing anyone trying to build the sources from his part
of the repository with any build system he likes.
nevertheless, i would recommend a system that would make the best
of the two worlds: be able to take advantage of the general pd-
extended build system and (at the users option) be able to not have
to use the pd-extended build system (probably at the cost of having
to do some manual configuration if the maintainer doesn't want to
maintain to configuration systems)
the simplest solution that comes to my mind is, that one of the 2
systems uses a differently named makefile.
since pd-extended's build-system is more likely to be called from a
parent makefile (because somebody wants to build the entire pd-
extended build-system), i suggest to name this Makefile.extended
(or Makefile.buildsystem)
anybody wishing to build using the extended build system, would
call "make -f Makefile.extended".
other users would just do a "make".
a more sophisticated method would use a Makefile.extended and a
Makefile.simple.
the ordinary "Makefile" would first check for the existence of the
extended build-system and if present, it would use
Makefile.extended, else it would use Makefile.simple.
if test -e ../../packages/Makefile.buildlayout
then
# cool, we can use the extended build system
make -f Makefile.extended
else
# simple fallback
make -f Makefile.simple
fi
what do you think?
