Hi,
I was resuming trying to build pytave on windows. As suggested by Tatsuro, I built 32 bit binaries for boost and just used Python27 downloaded from official python site.
After some tweaking (thanks to the config logs) I finally got to the last step of ./configure.
I am getting the error that linking to octave failed...
I have export LDFLAGS='-L/e/boost_1_61_0/stage/lib -L/e/octave_dev/lib32 -L/e/octave_dev/lib/octave/4.1.0+'
I tried exporting /e/octave_dev/lib but it gave errors so I exported /e/octave_dev/lib32 instead... It solved some problems but still I get some errors regarding undefined references!
.
In /e/octave_dev/lib/octave/4.1.0+ there are 3 files ending in '.dll.a'... I even copied them and renamed the copies to end in '*.a' instead of '*.dll.a' but still the same error.
The log says:

What libraries do I need to build the above program?
