Re: [osg-users] Problem compiling OSG from SVN in Cygwin
Hi Brian, I can't spot what might be up, there wasn't any changes to the core OSG to support the cfg plugin, so the addition of it should just the building of it and nothing else. Other changes checked in for other reasons might affect the build and this in turn could effect the cfg plugin. Its not entirely clear to me which bits work out of the box with the SVN version of the OSG, so its not clear what needs to be done to fix the build. Working on the assumption that its just the include order in the cfg plugin that is leading to some functions/macros being redefined/redefined I've moved the OSG includes to the tops of the files - things still compile under Linux so it would seem the changes are benign... but of course can't say how Cygwin will fare with them, perhaps no effect, perhaps a fix, perhaps make it worse... Could you check out the latest version in SVN and let me know exactly what things work/break out of the box without any further changes. Cheers, Robert.

[osg-users] Problem compiling OSG from SVN in Cygwin
Hello Robert,
It's your worst nightmare again. I tried compiling the svn version
again from trunk since you were asking folks to check various
platforms.
I downloaded fresh from svn and did the ccmake and then ran make and I
get this error:
[ 78%] Building CXX object

So then in include/osg/Math I change line 206 from this:
inline bool isNaN(float v) { return isnan(v); }
to
inline bool isNaN(float v) { return isnanf(v); }
and I change line 207 to return various forms of isnand, _isnan,
_isnand just to see what will happen and
then the build blows up much earlier on Animationpath in OpenThreads as
follows:

This error which would lead me to believe that during the early stages
of the compile - isnan is defined and then it disappears by the time I
get to osgdb_config.
Further on this is that I found if I change line 206 to
inline bool isNaN(float v) { return isnanf(v); }
and line 207 to
inline bool isNaN(double v) { return __isnand(v); }
then everything compile - any thought on this
