Author: Carl Worth <[email protected]> Date: Fri Sep 27 14:01:48 2013 -0700 Use -Bsymbolic when linking libEGL.so For some reason that I don't yet fully understand, Glaze does not work with libEGL unless libEGL is linked with -Bsymbolic.[*] Beyond that specific reason, all of the reasons for which libGL.so is linked with -Bsymbolic, (see the commit history), should also apply here. [*] The specific behavior I am seeing is that when Glaze calls dlopen for libEGL.so, ifunc resolvers within Glaze for EGL functions are called before the dlopen returns. These resolvers cannot succeed, as they need the return value from dlopen in order to find the functions to resolve to. I don't know what's causing these resolvers to be called, but I have verified that linking libEGL with -Bsymbolic causes this problematic behavior to stop.
