OPENGL in HPUX11.00

[shajitht_1]

Hi All

I am facing some problem with openGL with HPUX11.00 .
When I am trying to compail any programe in CC with OpenGL support it is giving th following error . but the programe is getting compailed .

bash-2.03$ /usr/local/bin/make
Linking run/iitzeus
/usr/ccs/bin/ld: Thread local storage symbol HP_OGL_VAPI_TLS imported from shared library /opt/graphics/OpenGL/lib/libogltls.2 conflicts with symbol in grid/grid_quality.o
make: *** [run/iitzeus] Error 1 .

if any body has come accross such issues pls help me .

regards
shajith

Hi

The symbols HP_OGL_VAPI and HP_OGL_BAPI
are defined on 10.20 while On 11.00, they are renamed to be HP_OGL_VAPI_TLS and HP_OGL_BAPI_TLS because at 11.00 OpenGL supports threads.

I suspect that somewhere in your build you are including a library or object module that was built on 10.20 whichneeds to be rebuilt on 11.00.

get latest 3D Graphics patches installed:

That is

hp-ux_patches/s700_800/11.X/PHSS_25253
hp-ux_patches/s700_800/11.X/PHSS_25255
hp-ux_patches/s700_800/11.X/PHSS_25254
hp-ux_patches/s700_800/11.X/PHSS_25261
hp-ux_patches/s700_800/11.X/PHSS_23546
hp-ux_patches/s700_800/11.X/PHSS_25262

including dependencies.

Something odd has happened in compiling grid_quality.o. The
HP_OGL_VAPI_TLS array is normally declared as an extern in /opt/graphics/OpenGL/include/glHpInt.h via your code using
#include
The header files have compiler pragmas that change OpenGL calls like glVertex3f into calls using pointers from the array. That makes the function calls faster.

OpenGL code should always result in a reference to HP_OGL_VAPI_TLS and not a definition of it. You could have a close look at what is in that source file, how it is compiled, and maybe the preprocessor output from compiling it with a "-E" option. The problem may be cleared up by a compiler or linker patch. There have been problems related to OpenGL calls that have been corrected in those patches.
