#125 build errors on OpenBSD 3.6 with partial solution
I just downloaded PyOpenGL-2.0.2.01.tar.gz and
attempted to build, but I got errors that GL/glu.h, etc
wasn't there.
In config/openbsd.cfg:
include_dirs=/usr/include:/usr/local/include:/usr/X11/include
Should be:
include_dirs=/usr/include:/usr/local/include:/usr/X11R6/include
which I then got errors in
src/interface_util/interface_util.c:
src/interface_util/interface_util.c:8: syntax error
before `#'
src/interface_util/interface_util.c:xx: stray '\' in
program
...
src/interface_util/interface_util.c:13: syntax error
before `switch'
error: command 'cc' failed with exit status 1
Once the '\' were removed I still got (when starting
build_clib):
src/interface_util/interface_util.c:8: syntax error
before `#'
src/interface_util/interface_util.c:13: syntax error
before `switch'
error: command 'cc' failed with exit status 1
Which I cannot resolve. ie I don't know what's the
problem with:
#define _PyTuple_From(NAME, BASE, PY_OBJECT)\^M
PyObject* _PyTuple_From##NAME(int len, BASE* data)^M
Logged In: YES

Those ^M's are the unix-ish way of displaying a
windows-style \r\n line ending. For some reason when you
are unpacking the source it's not properly converting the
line endings. This could be a problem with the source
archive, but it would seem the compiler *should* handle
foreign line-endings, no?

The ^M's aren't the problem (I beleive that gcc ignores
them). There are extra '\'s which (apparently) give errors.
Though there is an error before that so that would be in
question. I removed them just incase (probably should've
mentioned that ;)). The errors with the '\'s might
(probably?) be one of those errors that go away after you
resolve the first one.
So on line 7,8 of src/interface_util/interface_util.c we have:
#define _PyTuple_From(NAME, BASE, PY_OBJECT)\^M
PyObject* _PyTuple_From##NAME(int len, BASE* data)\^M
But I have no clue with might be wrong here. I've never
done something like this before. Apparently it has
something to do with the ##.
Or maybe it's the # in the #define and the error is in
src/config.h?
Here's the output from a clean extract, patched openbsd.cfg
(python setup.py build):

Sorry if I've wasted some time here, but, as an after
thought, I was poking around the output aside from the
errors given and found that pyopengl requires (?) swig
1.3.23. OBSD has only 1.3.21. Given that the name of this
file is interface_util.c, could this be the issue? Or is
1.3.21 ok? Or does this even matter given that it tries
anyway?
You fixed the openbsd.cfg, yes?

I just noticed as well, in config/openbsd.cfg the same path
is incorrect for the library_dirs:
This:
library_dirs=/usr/lib:/usr/local/lib:/usr/X11/lib^M
Should be:
library_dirs=/usr/lib:/usr/local/lib:/usr/X11R6/lib^M
