build errors on OSX with python 2.4

#1

I have successfully built and installed wxPython, so that I can use the WXAgg backend for matplotlib. Now, trying to build matplotlib, I get the following error:

/usr/bin/g++ -bundle -undefined dynamic_lookup build/temp.darwin-
8.2.0-Power_Macintosh-2.4/src/_na_transforms.o build/temp.darwin-8.2.0-Power_Macintosh-2.4/src/mplutils.o build/temp.darwin-8.2.0-Power_Macintosh-2.4/CXX/cxx_extensions.o build/temp.darwin-8.2.0-Power_Macintosh-2.4/CXX/cxxsupport.o

error: command ‘/usr/bin/g++’ failed with exit status 1

I am using gcc 3.3, and ActivePython 2.4.1.

Any ideas as to what is going wrong?

Try removing /usr/local/lib from your link path or get rid of
/usr/local/lib/libstdc++.* .

Chris:

I got around this in the fink package by setting 'export CXX=gcc'.
