D'oh, I thought I read the python bindings were activated by default if
the python development environment is present.
The next problem I had is that the python bindings are getting
installed (contrary to everything else) into libdir unconditionally,
i.e. DESTDIR is not honored and I get:
running install_lib
error: could not create '/usr/lib/python2.6/site-packages': Permission
denied
creating /usr/lib/python2.6/site-packages
make[1]: Leaving directory
`/home/mbanck/debian/debichem/openbabel-2.3.0/obj-i486-linux-gnu'
The command run is:
make -j1 install DESTDIR=/home/mbanck/debian/debichem/openbabel-2.3.0/debian/tmp
I tried adding a DESTDIR at various places in scripts/CMakeLists.txt,
but to no avail so far, I will open a tracker item for this.
Anyway, I need to support building two different python versions (or
rather, all currently (by Debian) supported python versions, which is
(dynamically determined at build time) 2.5 and 2.6 right now), so I
looked into manually building the python bindings via setup.py again and
finally managed to get this working I think.
Thanks,
Michael
PS: I had an issue where after I ran cmake/make in the source directory
it left an empty include/openbabel/babelconfig.h, which also lead to the
above error about "expected constructor, destructor, or type conversion
before ‘void'" even if I built it from a build directory.
