[SciPy-user] Compiling SciPy on Windows

[Bill Baxter]

Hi everyone,
I'm following the instructions on building SciPy for Windows here:
   http://www.scipy.org/Installing_SciPy/Windows

I've managed to get ATLAS and Numpy built, and now I'm up to scipy.

Using the standalone MinGW compiler I get an error about unresolved symbol
__EH_FRAME_BEGIN__.

I tried using the msvc.net 2003 compiler too (despite warnings on the above
web page that it wouldn't work).
After fixing a couple of compilation errors in Lib/special/cephes, I got
this:

No module named msvccompiler in numpy.distutils, trying from distutils..
customize MSVCCompiler
Traceback (most recent call last):
  File "setup.py", line 50, in ?

200, in CCompiler_customize
    self.compiler_so.remove('-Wstrict-prototypes')
AttributeError: MSVCCompiler instance has no attribute 'compiler_so'

Ok, I didn't really expect MSVC to work, just gave it a try.

But can anyone shed light on the __EH_FRAME_BEGIN__ error with MinGW?

I just installed this mingw:
C:\usr\pkg\scipysvn>gcc --version
gcc (GCC) 3.4.2 (mingw-special)

And just downloaded scipy from SVN.


Here's the full text of the error with MinGW:

Thanks for any help on this.
