Re: [osg-users] Build problems with osgviewerFLTK (OSG 2.6.0)
HI Cliff, This type of error comes from gcc now being tighter w.r.t inclusion of C style headers so that if you want access to the functions in these C headers you now need to explictly include them. It's not a bug in gcc, and not a bug in the OSG, it just one of those moving targets that we as developers need to keep track of - and the OSG svn/trunk is a bit further along this path so you could try updating to svn/trunk to see if the problem is any different. Adding cstring as an include will break the MipsPro compile so isn't portable enough for the OSG, but including the C header will be. I couldn't work out precisely where you need to add a header and don't have Suse to test against so I'll leave it to you divine what needs to be done, one you do could post the changes to osg-submissions.

Hey guys, I moved to a new development box with openSUSE 11.0 (x86_64), so I had to rebuild OpenSceneGraph.
