[ggt-devel] Compiler warnings

[Kevin G. <go...@gm...>]

Hello.

I'm compiling a VR Juggler app against GMTL version 0.5.4 using g++
version 4.1.3, and I'm getting the following warnings:

/usr/local/include/gmtl-0.5.4/gmtl/Math.h: In function 'float
gmtl::Math::fastInvSqrt(float)':
/usr/local/include/gmtl-0.5.4/gmtl/Math.h:382: warning: dereferencing
type-punned pointer will break strict-aliasing rules
/usr/local/include/gmtl-0.5.4/gmtl/Math.h:384: warning: dereferencing

/usr/local/include/gmtl-0.5.4/gmtl/Math.h:394: warning: dereferencing

/usr/local/include/gmtl-0.5.4/gmtl/Math.h: In function 'float
gmtl::Math::fastInvSqrt3(float)':
/usr/local/include/gmtl-0.5.4/gmtl/Math.h:403: warning: dereferencing

/usr/local/include/gmtl-0.5.4/gmtl/Math.h:405: warning: dereferencing
type-punned pointer will break strict-aliasing rules

Is there a way to disable this particular warning for this particular
GMTL header file (assuming that it's safe to ignore the warning)?

Thanks!
