"unresolved externals" error message building pywin32 for pypy

[jasonveldicott]

Hi,

I get an "unresolved externals" error message when building pywin32 for pypy, 
as listed below.  Both are the latest versions, 
amauryfa-pywin32-pypy-2a1da51e8152 and pypy-2.0.2.  As per build requirements, 
VS2012 and Win 7 SDD are installed.

Not sure what the error msg indicates, but maybe the python lib in linking is 
missing some required functions.

Possible cause of error may be a python installation on the same system (build 
could be using python lib instead of pypy lib), but python has been removed 
from path, and its folder name has also been changed.

Any suggestions as to cause of this error would be appreciated.

Thanks

Jason

That did the trick, thanks.  

I had the impression from another post that the breaking up of command strings 
into subprocess arguments could be done arbitrarily as needed to deal with 
nested inverted commas.  Obviously as you've shown, this is not the case, at 
least for Popen.

The r string notation at least saves having to double type a bunch of 
backslashes, although the appearance prepended to the string takes a little 
getting used to.

Visually the separate array to handle arguments is perhaps cleaner, having more 
resemblance to the original command.

Thanks for the tips.
