I can see the problem now from a local test.
Hmm i'm a bit confused. The JNI code uses GetStringUTFChars calls [1] for all char * arguments going from Java to C, which is an array of bytes representing the string in modified UTF-8 encoding. Is this OK? The other option is to use GetStringChars which is unicode...

The py-lmdb project have a comment [1] about reusing Python.h headers which seems to work for them.

We force-include # Python.h everywhere since it has a portable definition of ssize_t, which # inttypes.h and stdint.h lack, and to avoid having to modify the LMDB source # code. Advapi32 is needed for LMDB's use of Windows security APIs.
Note in ITS#8067 we added an ssize_t typedef for MSVC. Also in #8069 we changed to explicitly use the ANSI APIs, so if you're using Unicode file paths that will certainly be garbled now.

The actual build command:

That's the thing, the build doesn't complain about anything missing. But the binary seems broken because tests fail randomly.
A user tried the generated binary on his machine and it worked but also said...

Hi
I'm trying to build LMDB with Java/JNI bindings with Visual C++ Project Builder 9.00.30729 (vcbuild).
Unfortunately, vcbuild don't ship with inttypes.h, stdint.h, or a sane ssize_t. So I searched around and found a few candidates [1] of inttypes.h and stdint.h that seems to be working for py-lmdb.
However, unistd.h seems broken for windows - and the python guys use python.h instead.
Any ideas where I might find a good unistd.h?
I see you have one already - what is wrong with it, what definitions are missing?
Cheers, -Kristoffer
