Re: Fwd: Mangled Mesa compile failure

Dear Mr. Patel:

Your configure is different with mine. my configure doesn't have osmesa enabled.  when you enable osmesa,mangled mesa can be built since version 6.5.

I recently updated our mangled Mesa build on Linux for 7.11.2, and I hit no real problems with glX. 
This is what I did:
CXXFLAGS="-DUSE_MGL_NAMESPACE" \CFLAGS="-DUSE_MGL_NAMESPACE" \./configure \    --prefix `pwd`/build/Linux64 \    --enable-debug=no \    --disable-driglx-direct \    --enable-gl-osmesa=yes \    --disable-glw \    --disable-glut \    --with-driver=xlib \    --with-dri-drivers=  \    --with-osmesa-bits=32 \    --with-gallium-drivers= \    --disable-egl \    --enable-64-bit
gmake -j4gmake install
I did notice that with 7.11.2 both OSMesa and libGL contain gl* symbols, where as our older 7.7.1 build linked OSMesa against libGL and we avoided the duplication. I do recall trying --enable-shared and rejected that route for a reason I don't recall. 
On windows the situation is completely different I have still to get a fully working version of mangled mesa version - I am almost there but it has been non-trivial to first get a building version of mesa and next ensure the symbols are mangled. Once I have something ready I will probably post some info so others can avoid the headache.
I hope this helps,
Viral

Hello there:

I could not compile mesa with

./configure CFLAGS="-DUSE_MGL_NAMESPACE" CXXFLAGS="-DUSE_MGL_NAMESPACE" --prefix=/home/li/wci.llnl.gov/codes/visit/2.0.0/visit2.0.0/3rdparty --without-demos --disable-gallium --disable-glw --disable-glu --disable-egl --enable-shared --disable-static

make always fails at glxcmds.c with error messages like these:

glxcmds.c:1413: error: ‘glXGetCurrentDisplayEXT’ aliased to undefined symbol ‘glXGetCurrentDisplay’
glxcmds.c:1581: error: ‘glXQueryContextInfoEXT’ aliased to undefined symbol ‘glXQueryContext’
glxcmds.c:1925: error: ‘glXGetFBConfigAttribSGIX’ aliased to undefined symbol ‘glXGetFBConfigAttrib’
glxcmds.c:1929: error: ‘glXChooseFBConfigSGIX’ aliased to undefined symbol ‘glXChooseFBConfig’
glxcmds.c:1934: error: ‘glXGetVisualFromFBConfigSGIX’ aliased to undefined symbol ‘glXGetVisualFromFBConfig’
glxcmds.c:2674: error: ‘mglXGetProcAddress’ aliased to undefined symbol ‘glXGetProcAddressARB’

I have tried every mesa release from version 6.0 to the latest 8.0.

so,anyone one know how to get mangled mesa work?

attached is a snapshot from debian 6.0 terminal window.

thanks in advance.
