Hello everybody!
I would be glad if you could help me with my problem:
I tried to build the acual source code (commit 3d33ea0) using MSVC by typing "pyhon setup.py build" on the Visual Studio Command Prompt (2010).
Unfortunately I got the following linker error:
python34.lib(python34.dll) : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'
See the detailled output attached (build.txt)
My situation is as follows:
* Windows 7 Professional, SP1, 64 bit
* jdk1.8.0_25, 64 bit
* Python 3.4.3 |Anaconda 2.2.0 (64-bit)| (default, Mar 6 2015, 12:06:10) [MSC v.1600 64 bit (AMD64)] on win32
* Windows SDK 7.1 and Visual Studio Express 2010, details see msvc.png
It would be great if you have a tip to solve this problem.
Thanks in advance.
Best regards,
Günther

The error indicates a problem with 32 bit vs 64 bit, though I'm not quite sure what is wrong there. Since you're building with Python 3, did you follow all the steps on the wiki?
For 64 bit support you need to install a specific version of Windows SDK and then you need to build with a special command prompt.

Hi Nathan!
Thank you for your answer. It's quite tricky....
My mistake was that I used the Visual Studio Command Prompt (2010) rather than the Windows SDK 7.1 Command Prompt from the Windows start menu!
Then it is necessary to set the following envs:
I got this info here: https://github.com/cython/cython/wiki/CythonExtensionsOnWindows
At the end I was able to build jep (commit 3d33ea0) with those commands:
python setup.py build
python setup.py install
Thanky you very much! I wish you merry christmas and a happy new year!
