Wine is a good suggestion, but it takes up 3.53 MB. Is there a lighter
alternative?
So far, you didn't state whether the DLL actually uses Windows calls, but I
would imagine it does, and if so, you can't use it on anything but Windows
without emulating those calls, thus using Wine.
Sorry for not being more specific, the DLL actually uses Windows calls.
If it's available in source form (C? C++? What else?), you can extract the
part that's interesting to you and wrap that using Cython or ctypes (with
Cython being substantially faster than SWIG or ctypes).
The Source is C. I've heard of Cython, would Cython be a more portable
alternative?
It's likely not more portable than SWIG.
However, you didn't give us any hints about what the DLL actually does, so
we can't know if you really need to go that path or if you just failed to
find the obvious portable alternative.
The DLL wraps a device driver, and the library of the SWIG wrapped device
driver calls is invoked from a Python app. I was trying to find how this
device driver (DLL) could be used on Linux without having to re-write the
whole driver code for Linux.
Again, you're not giving us enough information - what kind of device are
you talking about?
Generally speaking, I doubt that a Windows device driver is of any use on a
non-Windows operating system. There are exceptions such as NDISWrapper
http://en.wikipedia.org/wiki/NDISwrapper
but they are just that: exceptions. It's hard to emulate enough of the
Windows driver support layer to make use of a Windows driver.
Anyway, this is no longer a Python problem, so this is getting off-topic
for this list.
