When I install xf86-video-intel-2.3.2, Package requirements were not met. And " yum list | grep xorg-server " can not find such package. Where can I get these packages (xorg-server xproto fontsproto)? Thanks in advance. The log information is below: ./configure ...... checking pkg-config is at least version 0.9.0... yes checking for XORG... Package xorg-server was not found in the pkg-config search path. Perhaps you should add the directory containing `xorg-server.pc' to the PKG_CONFIG_PATH environment variable No package 'xorg-server' found configure: error: Package requirements (xorg-server xproto fontsproto ) were not met: Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables XORG_CFLAGS and XORG_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
