root5 @5.34.13: Undefined symbols: ___GLXEW_ARB_multisample (on 10.5 i386)

[ryandesign (Ryan Carsten Schmidt)]

On Leopard i386, building root fails with:

:info:build Undefined symbols:
:info:build   "___GLXEW_ARB_multisample", referenced from:
:info:build       ___GLXEW_ARB_multisample$non_lazy_ptr in TGLFormat.o
:info:build ld: symbol(s) not found

Can you test if you can build ROOT outside MacPorts, standalone ? If you do please do so first disabling ROOT own internal checks for fink/MacPorts installation, by passing the option --disable-fink (yes, thats the right one, it does both....).

If that works, then please try with --enable-fink.

We need to first determine if this is an upstream issue, or a MacPorts issue.

There is a similar report at

Citing:

Problem solved. I had libGLEW.dylib from MacPorts, and a variant made for the mac framework, not to work with x11. Changing this with

sudo port install glew +x11

seems to have fixed

I'm not sure if it's exactly the same, but ...

I changed the title, even though root5 @5.34.13 technically doesn't exist (but I have no confirmation that this is still the problem with the latest version).
