A couple of others will cause problems:
The os.lstat import in sconstruct laso won't work under windows. It
might be possible to replace it with os.stat, but I'm not sure if this
will work. In any case the sconstruct script is only required for
compiling the curve-fitting code, so is entirely optional.
We should probably import with 'try:' statements (where necessary) so
that compilation is possible in Windows. I'm a bit disappointed that
the supposedly 'portable' os module doesn't fail silently or provide
dummy functions for Windows!
os.spawnlp in palmer.py will fail under windows. A simple os.spawnl will
work as a replacement, but this requires an exact path to Modelfree
(spawnlp uses PATH to find the executable, spawnl doesn't). Again, this
functionality is fairly peripheral - it is just an interface with
Palmer's Modelfree software. Simply removing the offending import should
work unless you particularly want to work with Modelfree.
This 'spawnlp' one will cause a fatal ImportError on Windows. However
as Modelfree4 only runs on UNIX systems then another 'try:' statement
is sufficient. I'll make the changes to the 1.2 line in the
repository. Don't worry about this Daniel, all you have to do is as
Chris said. Deleting the entire 'from os import ....' from the file
'generic_fns/palmer.py' will fix the problem. Once relax is happily
up and running on MS Windows I'll tie up some loose ends and make a
1.2.7 release of relax.
