[Numpy-discussion] Installing numpy with MKL

I feel a bit silly :-)
The compile now appear to work. Sort of. I discovered I had sneaken in a 
"pthreads" in the mkl_libs line, which is obviously not in the 
mkl-directory (I had stolen this line from a stand-alone program I wrote 
at some point). The error message is a bit confusing though - the python 
setup.py-script seems to claim that none of the libraries are there.

In any case the compile works now. However, when I try to run the python 
tests, python crashes because it cannot find libmkl_def.so. This is 
weird because LD_LIBRARY_PATH is set correctly. I also tried compiling 
with LD_RUN_PATH=$MKLROOT/lib/em64t but to no avail. I then tried adding 
mkl_def to the mkl_libs-line and now it works. However, I seem to recall 
reading somewhere that this is not a good idea. I guess that this is 
related to what your referred post was about? Did you end up using the 
patch or have you found a less invasive method since?

Now on to SciPy... :-)

Thankyou for your help
