Grass GIS wxPython startup error

[grruddy]

Grass was installed with the following options:

./configure --prefix=$INSTALL \

--enable-64bit --with-cxx \ --with-mysql \ --with-motif \ --with-cairo --with-freetype --with-readline \ --with-x --enable-shared \ --with-fftw-includes=$FFTW/include \ --with-fftw-libs=$FFTW/lib \ --with-mysql-libs=/usr/lib64/mysql \ --with-mysql-includes=/usr/include/mysql \ --with-proj-includes=$PROJ/include \ --with-proj-libs=$PROJ/lib \ --with-proj-share=$PROJ/share \ --with-gdal=$GDAL/bin/gdal-config \ --with-geos=$GEOS/bin/geos-config \ --with-python=/usr/bin/python-config \ --with-wxwidgets=$WXWIDGETS/bin/wx-config \ --with-cairo-includes=$CAIRO/include/cairo \ --with-cairo-libs="$CAIRO/lib $CAIRO/lib/cairo $pixman_LIBS" \ --with-cairo-ldflags="-lcairo -lpixman-1" \ --with-motif-includes=$LESSTIF/include \ --with-motif-libs=$LESSTIF/lib \ --with-freetype-libs=/usr/lib64 \ --with-freetype-includes="/usr/include/freetype2"

This install uses GCC-4.7.0 and a system packaged version of Python 2.6.6. Because Python is system packaged, the GDAL and wxPython support is appended to the PYTHONPATH environment variable and is not installed directly in the site-packages directory for python2.6. The installation went through without any issues, but now the following error occurs upon startup:

(attachment)

Text only mode works as expected, but the graphical issue needs to be fixed. Any help would be appreciated. Any additional information can be provided as need be. Also, it should be noted that this same installation was successful on a SLES 10 system ( this system is RHEL 6 ). The main difference being the GCC version and the fact that wxPython was installed directly to the site-packages of the SLES 10 Python installation.

Could you please retry with the current GRASS 6.4.svn?

[wenzeslaus]

Can somebody confirm that GRASS (any version) generally works on SLES 10 or RHEL 6 with Python 2.6 and GCC 4.7 or something similar?

If yes, please close the ticket and remove needinfo keyword.
