I recently updated to Python 2.7 from Python 2.6 and am running into issues
with pygccxml. Previously, I was on:
Python 2.6.6 (r266:84297, Aug 24 2010, 18:13:38) [MSC v.1500 64 bit (AMD64)] on
win32
I'm now on:
Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on
win32
On both systems, I have the latest versions of pygccxml/py++ installed from
SVN. I've diff'd the versions installed in both interpreter's site-packages
directory and they match exactly. When I run on Python 2.7.3, the suprocess
call to gccxml barfs. Here is an example:
INFO Parsing source file

There are a few extra print statements at the end, which line up to some
debugging code I inserted into source_reader.py:
print "COMMAND LINE*%s*" % (command_line,)
print type(command_line)
print "LENGTH", len(command_line)
The few lines beginning with "LINE" are just prints from the loop that reads
the stdout pipe after spawning gccxml. As you can see, the line is only 433
characters which is well within Windows limits. I've moved the project all
over the place and no matter where it's at, I get this error.
If I switch back to Python26, this is what I get:
INFO Parsing source file

As you can see, the command line is basically the same save the references to
the different Python installation. Length is also the same. It appears that
someting in subprocess changed in 2.7 that doesn't play nicely with how gccxml
is being launched.
