Purify version 18.104.22.168-002 appears to be incompatible with OpenGL. To work around this issue vaporgui can be linked with Mesa. The following steps should be followed:
1. ssh -X to storm
2. edit the base.mk file, prefixing the link line with the 'purify'
command (see attached base.mk file at the top)
3. Set the LD_LIBRARY_PATH:
setenv LD_LIBRARY_PATH /glade/proj3/DASG/VAPOR/third-party/apps-2.2.0/Linux_x86_64/Mesa-7.8.2/lib/
(the above path is current as of 6/24/2014)
4. Set the PURIFYIOPTIONS env variable:
setenv PURIFYOPTIONS "-enable-exclude=yes -exclude-libs=libGL.so -cache-dir=/fs/blizzard/home/clyne/cache -always-use-cache-dir"
Be sure to replace "clyne" with your user name
5. force a relinking of vaporgui. E.g.
6. run the executable:
- There will be lots of error messages reported by purify that occur inside of various system libraries, Mesa, and Qt. These can be "suppressed"
- vaporgui runs extremely slowly over Mesa
- DVR and Iso should not be enabled as the 7.8.2 version of mesa does not support programmable shaders (and would be horrendously slow if it did)
