[Matplotlib-users] "typename" compile problem with pygtk (solution)

[Rich D. <dr...@in...>]

Hello,

Several users (including Humufr and Niklas Volbers) have reported on this
list a compile error building matplotlib with pygtk.  The error looks
something like this:

In file included from src/_gtkagg.cpp:8:
 /usr/include/pygtk-2.0/pygobject.h:124: error: parse error before 
`typename"
 /usr/include/pygtk-2.0/pygobject.h:131: error: parse error before 
`typename"

I also experienced this problem.  It appears to be some sort of namespace
collision on the token "typename" (what this is colliding with isn't
clear).  By changing "typename" to "typname" or some other spelling in
/usr/include/pygtk-2.0/pygobject.h I was then able to build matplotlib
successfully.

If someone knows what is causing this and has a better solution, please
advise.  Perhaps it has something to do with GCC 3.4.x and that particular
pygtk release.

The problem is a bug in old versions of PyGTK, upgrading to a later version 
(2.4.1 I believe) will fix it.

Don't do that!  That looks brtually hackish.

Hello!

The problem was a problem with pygtk 2.4.0 and was caused by a parameter 
name "typename" which for C++ is also a keyword.  Any C++ application 
using pygtk was affected and agg (which matplotlib is using) is written 
in C++.  The fix to this problem was (among other few changes) to rename 
"typename" to "_typename", which was done in CVS shortly after pygtk 
2.4.0 was released.

In conclusion, just download pygtk 2.4.1 from pygtk.org and it will work!
