no, CXX is the problem (r.terraform and r.viewshed are C++). It should be g++ so it's using llvm. If GRASS is finding c++ by default, force it to what you want - add to your configure: CXX=g++ ----- William Kyngesburye <kyngchaos*at*kyngchaos*dot*com> http://www.kyngchaos.com/ "Time is an illusion - lunchtime doubly so." - Ford Prefect _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
