Description Alexandre Borges Marcelo 2013-01-17 16:43:27 UTC

After upgrading to gcc-4.6.3 I tried to rebuild blender-2.49b-r2, which gave the error: 'ptrdiff_t' does not name a type. According to http://gcc.gnu.org/gcc-4.6/porting_to.html, all I needed was to add <cstddef>. Following that, tring to rebuild gave the error described in https://code.google.com/p/bullet/issues/detail?id=481 and, after aplying the mentioned patch, blender built with no issues.


Reproducible: Always
