Hi Robert,
my nightly build worked fine on RedHat 5.3(64bits) but also on CentOS
6.3(64bits), WinXP(32bits)¨and Win7(64bits).
Thanks again for your quick answer and solution.
By the way did you think about how to correct the math.h problem
(regarding the round function, see discussion "[osg-users] [osgPlugins]
DDS Texture vanish with LINEAR_MIPMAP_LINEAR") ? In our environment I
have recompiled all OSG 3.0.1 and trunk replacing math.h by cmath in
include/osg/Math and didn't have any problems until now.
Cheers,
Christian

Hi Christian,
I have had a look through the OSG code base and there is mix of
GL_HALF_FLOAT, GL_HALF_FLOAT_NV and GL_HALF_FLOAT_ARB thanks to
various submissions at different times. This obviously isn't ideal so
I've replaced all the L_HALF_FLOAT_NV and GL_HALF_FLOAT_ARB usage with
GL_HALF_FLOAT and changed the #define in include/osg/Texture to
simply:
#ifndef GL_HALF_FLOAT
#define GL_HALF_FLOAT 0x140B
#endif
Could you do an svn update and let me know how you get on.
Thanks,
Robert.

Hi,
I just tried to recompile on a RedHat Enterprise 5.3 with gcc 4.7.2 the OSG
trunk. The compilation fails on ReaderWriterDDS.cpp on a "error :
'GL_HALF_FLOAT' not declared in this scope". I use Mesa 6.5.1, it's the last
release recognized by yum on RedHat (I know it's quite old... :-( ). In
include/osg/Texture, GL_HALF_FLOAT is defined only if
GL_ARB_half_float_pixel is not defined. The problem is that glext.h does
define GL_ARB_half_float_pixel, GL_HALF_FLOAT_ARB and GL_HALF_FLOAT_NV but
not the GL_HALF_FLOAT.
Adding to include/osg/Texture at line 400 :
#ifndef GL_ARB_half_float_vertex
#define GL_HALF_FLOAT 0x140B
#endif
corrects the problem on this type of configuration.
Does this mod induce any problems on other platforms ? What's your opinion ?
Cheers,
Christian
