SuRVoS won't compile on Windows -- Check windows compatibility

[bpavie]

I have the same issue on windows, can't compile it It come from the build.py file that is not made to work fro windows, e.g.; nvcc_path = os.path.join(home, 'bin', 'nvcc') should be nvcc_path = os.path.join(home, 'bin', 'nvcc.exe')

'lib64': os.path.join(home, 'lib64') should be 'lib64': os.path.join(home, 'lib','x64')

An others, so at then end I still have errors, the last one being:

y build_ext -i

Any guide on how to compile it on windows 64bits will be very helpful, I would love to test it! Benjamin

Hello Benjamin,

Thank you for the interest on SuRVoS. The error traceback and the changes you made to get there are really useful input.

I'm working on making the installation process compatible with windows right now. One quick solution seem to be to use MinGW32 (which I think requires 32-bit python) and then run the following command in the SuRVoS folder:

python setup.py build_ext -i -c mingw32

Which will force Windows to use MinGW compiler instead of the MSVCC built-in windows. Other options would be to install a better compiler than the window's default (such as Visual Studio C/C++ compilers).

However, I'm still working on an easy solution to make it work with the deafult windows compiler (MSVCC), as it seems that is possible since cudamat already supports it.

I'll let you know as soon as I get to a solution.

Thanks, Imanol

Hello, I similarly found and patched the issues identified by @bpavie and then tried to take your suggestion @imaluengo to try compiling with gcc under MinGW with the following failure:

python setup.py build_ext -i -c mingw32

I'm guessing that if I'm using MinGW perhaps I should back out of using the anaconda distribution of python and rather install it under MinGW,

Or do either of you have other suggestions?

Thanks, Malcolm

@imaluengo hello ,have you solved the problem,i have the same question,this puzzled me for a long time.thanks

Hi Hao,

I have compiled the windows version of SuRVoS. I am yet to commit back the changes to repository.

branch pyqt5. now has updated version of survos with pyqt5 working on windows python 3.6 and linux. Windows python 2.x is not supported as cuda > 7 is not supported by VS2008.
