[Mesa3d-dev] undefined symbols and silent fallback to swrast

[Xavier C. <cha...@gm...>]

14:47 < lb1> the fact is that if you remove a function from mesa .c file,
             everything will succeed, but the resulting driver will fail to load
14:47 < lb1> because it cannot resolve that symbol
14:48 < lb1> not sure why
14:48 < lb1> I suppose even for shared libraries gcc/ld should fail on
             undefined symbols
14:48 < lb1> maybe the makefiles disable that checking

Can anyone shed any light on this, why the driver always succeeds to
build and link even in the case of undefined symbols ?

The second question is why the dlopen errors are not visible by
default and require LIBGL_DEBUG=verbose to be displayed.
It does not make sense to always print these errors by default ?
