Building error of GLEWContextStruct in arch linux

I properly followed the documentation for building mitsuba. I am currently getting an error below.

I also got the same error. I wonder if you solved the problem? Thanks!

Refer to the homepage of glew, "MX discontinued" since GLEW 2.0.0. You can refer to my notes on compiling Mitsuba on Arch Linux or directly use the dependencies_arch although further modification in config.py is required.
