What steps will reproduce the problem? 1. python setup.py install

What is the expected output? What do you see instead?

I'd expect the package to install to my c:\Python26 packages dir.

What version of the product are you using? On what operating system?

1.0b3

Hi I've downloaded your noise and tried to install it via python setup.py install and get an error 'error: Unable to find vcvarsall.bat'.

After a bit of googling I'm under the impression i need visual studio installed for that bat file. Is visual studio required for install?

Can I install just the python part without the C libraries?

thanks!

Actually here is the full error:

pink@ganj ~/noise-1.0b3 $ python setup.py install running install running build running build_py running build_ext building 'noise._simplex' extension error: Unable to find vcvarsall.bat

Yes, python requires a compiler (visual studio by default) to compile C libraries on windows. Did you try the noise binary for windows available here?

http://caseman.googlecode.com/files/noise-1.0b3.win32-py2.6.exe

It does require python 2.6, which happens to be much easier for compiling libs on windows than 2.5 was.

I had that problem too, but now on python 2.7 i get this problem after i installed visual studio c++ 2008(2010 didn't work...):

HALP!

I'm not a windows compiler user, but this python bug sheds some light: http://bugs.python.org/issue7511

Notably:

"Martin v. Löwis (loewis) * Date: 2010-12-23 13:43 IIUC, the issue is that people installing a 64-bit Python, and VS Express, and then wonder why they can't build extension modules. I'm not so sure that there is a bug in Python here - this setup is not supported (and that's really Microsoft's fault). Now, automatically finding the SDK would be a new feature, IMO: if you want to use SDK tools, you are supposed to set DISTUTILS_USE_SDK, after opening the respective build environment. IIUC, installing VS express would not have been necessary in this setup at all - just install the SDK.

Alternatively, people can install Visual Studio proper, or use a 32-bit Python."

So it seems to be a problem with distutils finding the proper compiler when multiple compilers are installed. I am not in a position to fix this bug myself, but if you find a solution, please let me know.
