Agreed. This patch *fixes* glext.h, but I do not use it anywhere. It is fixed just in case someone crazy enough wants to use it. More importantly, it fixes gl_mangle.h, which is included by glapi_getproc.c when compiling a *mangled* OSMesa. > - Do you set USE_MGL_NAMESPACE when building the demo app ? better than that, I add "-include $osmesaprefix/include/GL/gl_mangle.h -include $osmesaprefix/include/GL/glu_mangle.h" to the CFLAGS, so that I am certain only the mangled versions will be used. See the last 10 lines of my build script at <a href="https://github.com/devernay/osmesa-install/blob/master/osmesa-install.sh#L653">https://github.com/devernay/osmesa-install/blob/master/osmesa-install.sh#L653</a> > - Is this issue specific to static linking and/or !Linux systems ? I've tried building osmesa the other day it seemed fine. Did you try building a *mangled* osmesa? This issue only happens when building a *mangled* OSMesa on Linux, MacOS, and Windows. Of could, you should be careful to not link with the system's opengl, or you wont't have any undefined symbol. Non-mangled osmesa works fine, but the HUGE advantage of mangles OSMesa is that you can easily use both OpenGL and OSMesa in the same app. > - Do you see this problem isolated to the gallium and/or classic osmesa ? This affects all drivers using glapi, see the initial error message.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
