Re: Hello John, I am a PhD from CMU and I have some questions about scikits.bvp_solver. Would you give me a hand please?

[John Salvatier]

hey, sorry I never responded to this. I don't think the 32bit version should be an issue, 64 bit computers can usually use 32 bit software. 

It looks like there's some issue with the installer looking at both the mingw compilers and the windows compilers. 

Try downloading the source, unzipping it, and using the following command: "python setup.py config --compiler=mingw32 build --compiler=mingw32 install"

Hi John,

Thanks for your reply last time. I think I forgot to tell you my OS is Win 8.
Would that possibly be the reason causing this problem?

Wish to hear from you soon,
Jinxu
