[Numpy-discussion] Compile with atlas 3.7.17 fails

[Hanno K. <kl...@ph...>]

Hi, 

I don't know if this is a bug or just me doing something wrong (I
suspect the latter). I try to compile numpy-1.0rc1 with python2.5 and
atlas 3.7.17.

I have build the atlas library myself, it doesn't give any errors
under make test or make pttest, so it seems to be okay. if I try to
build numpy I get the following error:

creating build/temp.linux-x86_64-2.5/numpy/core/blasdot

build/lib.linux-x86_64-2.5/numpy/core/_dotblas.so" failed with exit
status 1

I then tried to recompile atlas with the configure options as:

configure --cflags=-fPIC
--with-netlib-lapack=/scratch/src/python_dist/LAPACK
--prefix=/scratch/python2.5

but the error still remains. I'm on a 2 CPU Intel Xeon machine with
gcc 3.2.3.

Any hints?
