weave support in pythonxy #108

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I downloaded pythonxy 2.1.14 to my windows xp box.
I have already tried quite a few things, to resolve this problem
therefore quite a few frameworks are installed on the xp machine.
I have installed the .net 1.1 framework, the .net 1.1 redistributable
package, the .net 1.1 sdk ( in the hope that this might provide the visual
studio 2003 7.1 compiler that pythonxy asks me to use if I want to build
extensions). I also installed the visual studio 2010 beta thing from
windows. I did not install visual studio 2008 express as several posts on
the internet seem to indicate that the compiler provided by this version is
not compatible with the one that pythonxy wants me to have, though I am not
sure.
Reproduction of the problem:
Write a program:
import scipy.weave
code = """printf ("hello\n");"""
COMPILER="mingw32"
COMPILER="msvc"
scipy.weave.inline(code,verbose=2,compiler=COMPILER)

where COMPILER is either mingw32 or msvc

I do not succeed in compiling with either.
As you can see from the errror outputs below, I do not seem to have
understood the msvc compiler. The program doesn't even find the
msvccompiler even though I have plenty of them lying around, with all my
sdks and .net and visual studio 2020 things installed.
The mingw32 error is more obscure, I don't understand the problem.
I attach the error messages that appear when repeating the compiler command
that throws the error in a file.

Ultimately, I would like port scipy/numpy/c++/pyqt extensions which run 
perfectly on linux to windows. I have also problems using swig which I will
report in another post.
Any help is appreciated.

my distutils.cfg file is the following:
[build]
compiler=mingw32
[build_ext]
compiler=mingw32

when compiling with msvc, the result is:

I comment my own post.
There is a typo : 
"visual studio 2020 things"
should be 
"visual studio 2010 things"
I also ran
distutils.ccompiler.show_compilers()
and it did show msvc as a compiler.
Although I am not sure what that means, as it also showed 
intel and intele which are certainly not installed.

There was an error in your code.
For example, with the following code, it works:
code = 'printf("hello");'
