What do you think of this one. Removed excess swig cruft,

You need to run

make swigify to generate those changes.

Ok, looking at this now. I don't completely get how it works. I'm
trying
to reproduce what you are doing by hand but nothing comes out of gcc:

[root@localhost src]# echo '#include "../include/selinux/selinux.h"'>
temp.c
[root@localhost src]# gcc -c temp.c -aux-info temp.aux
[root@localhost src]# ls temp.*
temp.c temp.o


I got this "sort of" working locally. It works when I call it directly
on the header but it leaves a .gch file sitting in the include
directory.

Trying to use stdin I get:

[root@localhost src]# gcc -x c-header -c - -aux-info temp.aux<
../include/selinux/selinux.h
<stdin>:569: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See<http://bugzilla.redhat.com/bugzilla>  for instructions.


Other comments:

The disconnect between swigify and clean targets remains: If make
swigify builds this, and it is checked in to the tree then make clean
shouldn't remove it, else it should be in the pywrap target and not
installed.

I'm not sure what the header re-ordering in selinuxswig.i and the
copytree/install functions have to do with this patch.

Merged in libselinux-2.0.87

I have VERSION 2.0.86 in git?
This seems to break make install-pywrap on the current selinux trunk:
bash exception.sh>  selinuxswig_python_exception.i
swig -Wall -python -o selinuxswig_wrap.c -outdir ./ selinuxswig_python.i selinuxswig_python_exception.i
swig error : Unrecognized option selinuxswig_python.i
Use 'swig -help' for available options.
This btw prevents use of Caleb's patches on Fedora 12.  If I can't build
and install the python modules from the selinux repo, then there is an
undefined dependency from the Fedora libsemanage-python module on the
upstream libsemanage (some symbol introduced in the Fedora patches to
libsemanage) and thus migrate.py is unable to import semanage and
aborts.
Hmm...if I make swigify, all is well again.  But something seems wrong
with the Makefile...

Lets stop carrying the patch for swigified c and py file from the package and force you to have to run make swigify in the build procedure.


I am fine with that, having an outdated swig wrapper has caused much more pain than having to have swig installed will.
