undefined symbol/libextmod.so/drmsetServerinfo

[Dwijadas Dey]

Hi
    List user's
                     i have compiled and installed xorg-server
1.7.99.2 on centos 5.7 [ Linux localhost.localdomain 2.6.39 #7 SMP Fri
Oct 14 21:11:17 IST 2011 i686 i686 i386 GNU/Linux ] preceded by Mesa
7.10.3 and libdrm 2.4.26 [ #pkg-config --cflags --libs libdrm
-I/opt/libdrm/include -I/opt/libdrm/include/libdrm  -L/opt/libdrm/lib
-ldrm ] Also i have compiled and installed xf86-video-intel-2.16.0 for
intel sandybridge support.

   But when i run startx -- /opt/xorg/bin/Xorg -verbose , X server
crashes, it gives the error as

dlopen: /opt/xorg/lib/xorg/modules/extensions/libextmod.so: undefined
symbol: XvMCScreenInitProc
(EE) Failed to load /opt/xorg/lib/xorg/modules/extensions/libextmod.so
(II) UnloadModule: "extmod"
(EE) Failed to load module "extmod" (loader failed, 7)

Another error that does not logs into logfile is -> undefined symbol:
drmsetServerinfo when it tries to load libdri
Also # ldd /opt/xorg/lib/xorg/modules/extensions/libdri.so
        linux-gate.so.1 =>  (0xb77f0000)
        libm.so.6 => /lib/libm.so.6 (0xb7799000)
        librt.so.1 => /lib/librt.so.1 (0xb7790000)
        libc.so.6 => /lib/libc.so.6 (0xb7637000)
        /lib/ld-linux.so.2 (0x0040f000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb761e000) does not
contain any drm info.

Whether the problem is related to libdrm or xorg-server ?
Looking forward for a reply
Thanks in advance
