Hello,
I have built openbabel on Snow Leopard and am now trying to build the python
bindings. After I build and installed openbabel, I cd'd to the scripts/python
directory and ran python setup.py build. setup.py failed because it tries to
copy openbabel.py onto itself with this line:
shutil.copyfile(os.path.join(srcdir, "openbabel.py"), "openbabel.py")
I then tried to fix this error by changing that part of setup.py:
try:
shutil.copyfile(os.path.join(srcdir, "pybel_py%dx.py" %
sys.version_info[0]), "pybel.py")
shutil.copyfile(os.path.join(srcdir, "openbabel.py"), "openbabel.py")
except shutil.Error:
pass
It then fails because it can't find an openbabel header. I tried to fix this
by changing the definition of obExtention from:
obExtension = Extension('_openbabel',
[os.path.join(srcdir, "openbabel-python.cpp")],
include_dirs=[os.path.join(srcdir, "..", "..", "include"),
os.path.join("..", "include")],
library_dirs=[os.path.join("..", "lib")],
libraries=['openbabel']
)
to:
obExtension = Extension('_openbabel',
[os.path.join(srcdir, "openbabel-python.cpp")],
include_dirs=[os.path.join(srcdir, "..", "..", "build",
"include"),
os.path.join("..", "..", "include")],
library_dirs=[os.path.join("..", "..", "lib")],
libraries=['openbabel']
)
The build and install seemed to work at this point, but when I'm in a python
prompt I get this error:
>>> import openbabel
Traceback (most recent call last):

ImportError:

Expected in: flat namespace

I tried setting the LD_LIBRARY_PATH like the install instructions suggest, but
it makes no difference.
Does anyone know what I'm doing wrong?
Thanks,
Craig
