Hi all, agreed. Personally, I rarely use the extended distro since i only need a few externals or library, and i don't like to be dependent on a large and probably hard to maintain build system. I advocate simple Makefile files that are self-consistent and Makefile.extended or whatever for Hans' GUBS. greetings, Thomas

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?
