Build fails on Ubuntu12.04(64bit) (python setup.py build_ext --inplace)

[Nash Chen]

Hi, When I build the C++ / Cython extensions of RLPy: python setup.py build_ext --inplace. I encounter a problem: running build_ext cythoning rlpy/Representations/hashing.pyx to rlpy/Representations/hashing.c

Error compiling Cython file:

...

cdef int BIG_INT = 2147483647

@cython.boundscheck(False) @cython.cdivision(True) cdef long hash(long [:] A, long [:] R, int increment, int max): ^

Can somebody help me? Thanks!

Thanks for filing the issue! I tried to reproduce your problems, but did not succeed. Which version of rlpy are you using? A stable release or the current master branch? Could you also let me know which cython version you are using (type cython -Vin a terminal)?

I had this issue too, and it was fixed by adding the Anaconda bin directory to the path (cython version is 0.20.2 in Anaconda and 0.15.1 in /usr/bin). Perhaps this should be mentioned in the "Getting Started" page.

Thanks for the suggestion. The next stable version of rlpy will be installable via pip, so (hopefully) this issue will not occur anymore.
