More precisely, the constructor provides C source code to access data
and metadata with files ReadIM{7,x}.{c.h}.
I wrote a tiny ctypes wrappers in order to have a object-oriented
class in python that handling reading the data files written by the
constructor software.
One issue is that ReadIM7.h includes zlib.h. On linux, it is easy to
install zlib-dev package. All is simple, as it is installed in
standard repertory. On windows of course no standards. How would you
then proceed? Do I have to distribute zlib.h, and also zconf.h,
zlib.lib, libz.a and libz.dll.a needed to get it work ? Or a simpler
solution is to only distribute binaries on this platform ?
Other issue: with all these files in ./src, I have the following
configuration:
ext = Extension('_im7',
sources=['src/ReadIM7.cpp', 'src/ReadIMX.cpp'],
include_dirs=['src'],\
libraries=['zlib',],\
library_dirs=['src'],\
define_macros=[('_WIN32', None), ('BUILD_DLL', None)], \
extra_compile_args=['-ansi', '-pedantic', '-g', '-v'])
it builds a _im7.pyd file that ctypes is not able to load as it
expects a _im7.dll file with
ctypes.cdll.loadlibrary('_im7')...
Is their a way to make distutils build a .dll file that could be
loaded by ctypes ? or using distutils in such a way is not the right
way to go ?
on linux, there is no trouble, distutils makes a _im7.so file that
ctypes can easily load...
Thanks
