=dev-python/pycuda-2013.1.1 does not compile under Python2.7 if cuda.h is not in include path. Emerge log fragment:

compilation terminated.
error: command 'x86_64-pc-linux-gnu-g++' failed with exit status 1

I found a cure for this disease. siteconf.py (generated by python_configure() ) should be copied to ${S}. See attached ebuild diff

Steps to reproduce the bug:
1) enable python 2.7 
2) make sure cuda.h is not available. 

echo '#include <cuda.h>'|gcc -xc - -o a.out

The command should fail:

<stdin>:1:18: fatal error: cuda.h: No such file or directory

3) update package.mask to allow =dev-python/pycuda-2013.1.1
4) emerge =dev-python/pycuda-2013.1.1. Result: error in src_compile()

Cure for the bug

Fixed ebuild compiles successfully

The trick is to put most of generated siteconf.py into directory containing setup.py (which happens to be ${S})

The grep command removes python version information from siteconf.py and sends the file to $S/siteconf.py

By the way, pycuda-2012.1 fails, too. Same symptom

Thanks for the report, I will look into it.

[Comment 6 Marius Brehler 2014-11-30 14:37:37 UTC]

Neither a problem with pycuda-2013.1.1 and nvidia-cuda-toolkit-6.5.19, nor with nvidia-cuda-toolkit-6.5.14.

Old version removed.  Please reopen if it still happens.
