Installing on Win 8

[tschm]

Hi Ulf, I am currently experimenting with your installer on Win 8 (I know that this is a bad choice in the first place). I install it via pip (using the requirements.txt) as

git+https://github.com/MOSEK/Mosek.pip@v7.0.0#egg=mosek

I run on Win 8 64bit machine. I have Python 2.7.10 (32bit). Mosek seems to install correctly as I end up with 4 .dll files in env\Lib\site-packages\mosek + some .py files.

When I try to import mosek I get File "C:\Users\thomas\Documents\GitHub\pyopt\env\lib\site-packages\mosekinit.py", line 639, in raise ImportError('Failed to import dll "%s"' % __libname) ImportError: Failed to import dll "mosekxx7_1.dll"

Hmm... Can you see if it installed to 32bit version of Mosek? In the 32bit distro the mosek dll is mosek7_1.dll, in the 64bit version it is mosek64_7_1.dll.

I tried with both. I figured that the problem is that those .dll files (to be precise the folder they are in) don't make it into the sys.path. I tried to change the path at runtime but had no success. For now I have modified the build.bat file (the file building my python environment, downloading mosek etc.) such that it will copy those .dll files into the local path of my project. It works but it's not that elegant :-)

mosek/init.py locates mosekxx7_1.dll relative to the script file's path. The Windows DLL loader will look for dll dependencies in the same directory as the DLL it loads (or at least it should). If it works when you set the PATH it should indicate the install paths are different that I expect when loading the dlls.

Haha, I think I found your bug (you owe me a beer):

In line 597 or your init.py:

    if ctypes.sizeof(ctypes.c_void_p) == 4:

      __libsupport.append('mosek7_0.dll')

    else:

      __libsupport.append('mosek64_7_0.dll')

You have to replace the two zeros with ones. After this change it seems to work...

Hi Ulf, can you please correct this little bug? This isn't actually related to the installer rather it's a problem of the Python part in the main mosek distribution. Thanks Thomas

[ulfworsoe]

It has to be fixed in the mosek distro. I have submitted the fix, and I thought that it had been built and uploaded. I'll ask the build guy.

This took longer that expected, but a new version that fixes the problem should be up now.
