[Numpy-discussion] Numpy with uclibc compiled python

Hey all,

We started to try and compile the numpy module on an embedded PowerPC 
Xilinx board with no luck.  This is one of the errors I get when I try 
to build the module on-board.  It is due to the fact that the compiler 
is located in a different location than the original compiler for python 
(i think).  I made symbolic links to fix the first error.  The second 
more critical error that I cannot recover from is the "Error: 
Unrecognized opcode: `fldenv'".  There are many more duplicates of this 
error, but it occurs when the "umathmodule.c" is being compiled.

I have tried changing the CFLAGS multiple times with no luck.  Python 
was compiled with uclibc libraries, so could this be the problem?  Is 
there any way we could compile Python and numpy together in one step?

I am using Binutils 2.17, GCC 3.4.6, and Python 2.5.  Again, python was 
compiled with uclibc, not the standard libraries.  We require the FFT 
module for a project that is due in about a week.  Any help would be

C compiler: 
-linux-uclibc-gcc -DNDEBUG -Os -pipe -fPIC

compile options: '-I/usr/include/python2.5 -Inumpy/core/src 
  -I/usr/include/python2.5 -c'
powerpc-linux-uclibc-gcc: _configtest.c
clibc-gcc: not found
clibc-gcc: not found

I made symbolic links to fix the above errors, but then I also get 
multiple assembler opcode errors when it tries to run the entry build:

powerpc-linux-gcc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC 
-Ibuild/src.linux-ppc-2.5/numpy/core/src -Inumpy/core/include 
-Ibuild/src.linux-ppc-2.5/numpy/core -Inumpy/core/src 
-Inumpy/core/include -I/root/python/include/python2.5 -c 
build/src.linux-ppc-2.5/numpy/core/src/umathmodule.c -o 
Error: Unrecognized opcode: `fldenv'
