[Numpy-discussion] can't build numpy 1.2.0 under python 2.6 (windows-amd64) using VS9
Wed Oct 8 09:56:02 CDT 2008
Just to note, on the compilation issue, I encountered this a while ago with
numpy 1.1.1 and I think Python 2.6b2, again because we wanted to skip Python
2.5 in my organization, largely because it was an issue to get working on
64-bit. I couldn't find anywhere 7.1 was available.
We discussed errors you are encountering a few months ago, they are related
to the compiler directives.
