Hi, I tried to build the i810 modesetting branch, but failed with following error, it was building okay with the master branch, I check out the modesetting branch, then it fails. I already set the path for pkgconfig. Any thing missing? Thanks!

Alternatively, you may set the environment variables DRI_CFLAGS and DRI_LIBS to avoid the need to call pkg-config.
