[Numpy-discussion] build problem: numpy with cygwin mingw

[Sebastian H. <ha...@ms...>]

Hi,
I just tried my first build  from a svn checkout on windows using 
cygwin. I want to use the non cygwin python - i.e. the non-cygwin 
(mingw) compiler more.
I get a presumably very basic error:
Even though I follow the simple instructions on
http://www.scipy.org/Installing_SciPy/Windows
calling
python.exe setup.py config --compiler=mingw32 build --compiler=mingw32 
bdist_wininst

I noticed that gcc gets called without the "-mno-cygwin".
 From this follows that  _WIN32 is not defined and than I get:
<copy-paste from cygwin>
Could not locate executable gfortran
Could not locate executable f95
customize GnuFCompiler
customize GnuFCompiler
customize GnuFCompiler using config
C compiler: gcc -O2 -Wall -Wstrict-prototypes

compile options: '-Ic:\python24\include -Inumpy\core\src 
-Inumpy\core\include -I
c:\python24\include -Ic:\python24\PC -c'
gcc -O2 -Wall -Wstrict-prototypes -Ic:\python24\include -Inumpy\core\src 
-Inumpy\core\include -Ic:\python24\include -Ic:\python24\PC -c 
_configtest.c -o _config
test.o
In file included from c:/python24/include/Python.h:82,
                  from _configtest.c:2:
c:/python24/include/intobject.h:41: error: parse error before 
"PyInt_AsUnsignedLongLongMask"
</copy-paste from cygwin>

The error in the last line I traced back to this line:
#define PY_LONG_LONG __int64
in pyconfig.h  which is used because
#if defined(__GNUC__) && defined(_WIN32)
is not true if gcc is called without "-mno-cygwin"

I don't have cygwin's python installed. I neither have cygwin's
non-mingw gcc installed....


According to http://www.python.org/doc/current/inst/tweak-flags.html
the --compiler=mingw32  should tell distutils to use the "Cygwin in 
no-cygwin mode"  !?!?

What's wrong here ?

Thanks
Sebastian Haase

PS: I don't even care about ATLAS... at this point
PPS:  Is there maybe a precompiled version later than 0.9.8 avaible !?

did you apply the patch from ticket #114, as mentioned on top of that 
page? The Cygwin build is known not to work otherwise (due to incorrect 
compiler flags, as you noticed)...

Hi Stephan,
thanks a lot ! Of course I did NOT read the small print at the top  ;-)

Now I just have to learn how to apply a patch ;-)
(Funny, that after more than ten years of Linux I still don't know this 
... )

Thanks again - I'm sure it will work now.
(I hope)

Hi all,
I was to quick with my last reply.
The patch in ticket 114 (http://projects.scipy.org/scipy/numpy/ticket/114)
refers (among others) to a file
distutils/system_info.py
but my windows python (version 2.4.3) does not contain any file like that in
C:\Python24\Lib\distutils

What am I missing this time !?

Thanks,
Sebastian Haase

Perhaps it's referring to the distutils folder in the numpy  
package .. should be in:
/path/to/numpy/checkout/numpy/distutils/system_info.py

Hi Steve,
Thanks for the hint. Before I was looking for numpy/distutils (which did 
not exist) and now I found it as numpy/numpy/distutils.
Done. Worked - thanks.


Now, I was trying to build SciPy - without getting through the 
ATALS/Lapack precedure ! So I get the expected Warnings (... NOT 
AVAILABLE)  but then (right after those) I get an error:
   File "C:\Python24\Lib\site-packages\numpy\distutils\system_info.py", 
line 403,
  in get_info
     raise self.notfounderror,self.notfounderror.__doc__
numpy.distutils.system_info.NotFoundError: Some third-party program or 
library is not found.

Does SciPy not come anymore with a fall back non-Lapack version included !?

Thanks,
Sebastian Haase
