I was able to build both 2.6 and py3k (trunk checkouts, revision 59136
and 59130 respectively) out of the box, except for openssl and tcl,
which I didn't try to install. The external libraries I placed as
sibling directories to the python source root dir, just as with the
previous PCBuild instructions. I didn't need to build in any specific
order, "Build solution" correctly resolved dependencies. I got the
alert box about solution folders but it didn't harm anything.
If anyone is curious, I ran pybench for both 2.6 and 3k build against
VS 2003 and VS 2008. This is using the out of the box settings, and no
PGO for 2008 (Express version doesn't have it). MSVC 9 was slightly
faster for 2.6, but somewhat slower for py3k. I'm not sure how
relevant that is, but (surprisingly to me) it's not an automatic speed
win over MSVC 7.1. The results of my pybench runs available here:
