I've never used Cython and am having a hard time figuring this out.
Could you send me the file 'scikits/sparse/cholmod.c'? This means that there's some C type that was forward-declared, but never actually defined, and then we tried to instantiate an instance of it. But I'll need to see the generated code to figure out which type '__pyx_t_10' is supposed to be.
Huh, this appears to be some bad interaction between numpy and cython, rather than anything to do with my code. The offending variable comes from doing 'cimport numpy as np' and then referring to 'np.NPY_F_CONTIGUOUS' -- this is being translated to: enum requirements __pyx_t_10; __pyx_t_10 = NPY_F_CONTIGUOUS; and then gcc is complaining that 'enum requirements' is an undefined type.
What version of Numpy and Cython do you have installed?
Cython 0.14.1, Numpy 1.5.1. Which versions do you have?
It looks like with Cython 0.12.1, which is what I was using before, it happens not to generate a temporary variable in this case, but Cython 0.14.1 generates the temporary variable.
I've just committed a workaround to the scikits.sparse repository: https://code.google.com/p/scikits-sparse/source/detail?r=ad106e9c2c2d55f2022... (I believe it works -- it does compile -- but technically I can't guarantee it since for me the tests are now failing with an "illegal instruction" error inside BLAS. But I think this must be an unrelated Ubuntu screwup. Yay software.)
And I'll see about poking Cython upstream to get this fixed...
Awh. Thanks! https://github.com/cython/cython/commit/a6ec50077990a9767695896076a8b573a5bd... Dag Sverre
