distutils problem windows xp python 2.4.2

[ajikoe@gmail.com]

Hello I tried to combine c++ and python together.
So I follow from this website:

http://kortis.to/radix/python_ext/

I have this code:
# prmodule.c
static PyObject *pr_isprime(PyO bject *self, PyObject *args){
int n, input;

if (!PyArg_ParseTu ple(args, "i", &input))
return NULL;

if (input < 1) {
return Py_BuildValue(" i", 0);
}

n = input - 1;

while (n > 1){
if (input%n == 0) return Py_BuildValue(" i", 0);;
n--;
}

return Py_BuildValue(" i", 1);
}

static PyMethodDef PrMethods[] = {
{"isprime", pr_isprime, METH_VARARGS, "Check if prime."},
{NULL, NULL, 0, NULL}
};

void initpr(void){
(void) Py_InitModule(" pr", PrMethods);
}



and my setup.py file:
from distutils.core import setup, Extension
module = Extension('pr', sources = ['prmodule.c'])
setup(name = 'Pr test', version = '1.0', ext_modules = [module])

------------------------------------
If I run setup build
I've got the following error message
running build
running build_ext
error: The .NET Framework SDK needs to be installed before building
extensions for Python.

I use visual Studio 2005.

Thanks,
pujo

You might take a look at:

http://groups.google.com/group/comp.lang.python/msg/2341e3ac80ae5052?dmode=source

it provides code to change your setup code to:
from distutils.core import setup, Extension
module = Extension('pr', sources = ['prmodule.c'])

for attempts in range(2):
try:
setup(name='Pr test',
version='1.0',
ext_modules=[module])
except SystemExit, e: pass # Failure. Patch and try again
else: break # Successful run, no need to retry.

print '*** Apparently a failure:', e.args[0]
print '*** Patching and trying again'
import patch_msvccompi ler

Hello Scott,

It didn't work with visual studio 5. .Net framework 2.0
Do you have any suggestions?

Thanks,

"It didn't work" is not very diagnosable.

....
It is so much easier with the actual error messages.

Ah-ha -- you installed the compiler but not the .NET Framework.
You have more downloading and installing to do.

See, for example:

Re: distutils problem windows xp python 2.4.2

Hello,

I have .net framework 2.0 because I' already able to run visual studio
express 2005.
Should I install .net framework 1.1 and also ms toolkit ?

Sincerely Yours,
pujo
