Thanks! Dan, After I reset the pkg_config path it works. It's strange, I tried to reset few times before but it didn't work. And now it just works.

I don't know if this is two different paths or a typo. Either export PKG_CONFIG_PATH=/tmp:/modular/lib/pkgconfig or export PKG_CONFIG_PATH=/tmp/modular/lib/pkgconfig Also, you probably want to append the current value for PKG_CONFIG_PATH unless you know it's not set or you know all the other .pc files are in /usr/{lib,share}/pkgconfig. export PKG_CONFIG_PATH=/blah:$PKG_CONFIG_PATH Finally, do you have libdrm installed? Is it's .pc file accessible to pkg-config? -- Dan </blockquote></div>
