[Numpy-discussion] Fail to compile Numpy on Cygwin

Hi Pearu,

Using just "python setup.py build" I get the following change in the
same error:

...
compile options: '-I/usr/local/include/python2.5 -Inumpy/core/src
-Inumpy/core/include -I/usr/local/include/python2.5 -c'
gcc: _configtest.c
gcc _configtest.o -L/usr/local/lib -L/usr/lib -o _configtest.exe
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
failure.
removing: _configtest.c _configtest.o
Traceback (most recent call last):
... 

I completely remove the build directory between builds, just in case
this helps.

Thanks a lot, and greetings,

Javier

In your build command

  python setup.py config --compiler=mingw32 build --compiler=mingw32
install

you are not using cygwin gcc compiler but mingw32. I think you cannot do
this - don't ask why, some time ago I failed to determine the cause.

Anyway, under cygwin just try

  python setup.py build

then it should just pick up cygwin compiler.

Or, execute

  python setup.py config --compiler=mingw32 build --compiler=mingw32
install

from Windows cmd line.

HTH,
Pearu
