Installing PyMC error - fortran compiler not found

[fj]

Hello,
I am trying to install PyMC on a Windows 7 x64, Enthought Python ,
using easy-install pymc - and I get the following errors after which
installation aborts. I tried to build from source using >>setup
install - and that too gives the same set of errors.

Any suggestions ?

I had success building PyMC on windows 7 with:

python setup.py config_fc --fcompiler=gfortran build

You need to install a FORTRAN compiler (gFortran). Please read the
installation instructions in the user's guide. I have uploaded Windows
installers to the GitHub site recently (see "Downloads" on
https://github.com/pymc-devs/pymc), so I recommend using those instead
of the ones on PyPi.

Whoa - those new plots are awesome!

Yes, I am having the same difficulties.  Before trying this, I did install the MingW gfortran compiler, but I don't know what configuration file or command line option to give to tell either the basic pymc setup or pip where that compiler is installed.  The default search does not work.  I am using WinPython, so if anyone knows of a tutorial or sketch where someone has installed PyMC using WinPython, I'd appreciate the reference.

Thanks!

We have conda windows packages now for 32-bit python. So if you run anaconda (32 bit on windows):

conda install -c pymc pymc

Should get you going.
