Hi Edward. I have spent several hours, to try to fix this issue. If you have winpython 64 bit, you need - Visual Studio Professional 2012 to compile. This is because: target_functions\relax_fit.c make an include to the header file #include <Python.h> And if you only have "Visual Studio Express 2012 for Windows Desktop", there will be a link error. I think then Scons try to compile x86, and the header files in python will not be matched. If you have professional, Scons try to compile amd64, and will find the correct link in the header files. (Or something like this ) This setup is listed here: http://nmr-relax.kimlinnet.dk/index.php?title=Installation_windows_Python_x86-64_Visual_Studio_Express_Professional But I am happy to announce, that with python 32 I have NO errors!

Ok, then we'll have to go with that. It's good that the icons are back :) Could I ask you to make one more small change to patch3 (https://gna.org/support/download.php?file_id=18123). Could you add a line or two to the comments with information about the WinPython version that you are using, and anything else to do with WinPython that you think might be important? It would be good to make it clear in the comments that this is not results from the official Python sources.

And I am enjoying the icons in the menu. :-) /Troels 2013/6/20 Edward d'Auvergne <edward@xxxxxxxxxxxxx>:Does this work with places=2 or 3 for the te value? That would be better. The precision is shocking, I have to say. I would suggest that in the comments, that something about this being the WinPython distribution would also be useful for these precision records. I would not think that it is the Microsoft C compiler that is a problem, but rather the numpy packages bundled with this Python derivative. The Microsoft compiler has never been an issue before, so I would suggest that the WinPython people have a precision bug in their code. Or maybe they have deliberately turned down their precision so that it appears as if their distribution is much faster than standard Python+numpy? Is it also WinPython that has problems with icons in the menus? Regards, Edward On 20 June 2013 09:18, Troels E.
