I have an amd64 box, and I installed mplayer by compiling the code using the convention ./configure, make and make install sequence. When configuring mplayer, I have this errors in configure.log, indicating impatible libXext as shown below. Then I use YUM update to update my FC3 335 packages, including all xorg-x11 x86_64 rpm packages. Reboot the system, re-do the ./configure. I still got the same error. Appreciate any one for any hint and help. Here the cut-out from configure.log indicating incompatible libXext. ============ Checking for X11 ============ #include <X11/Xlib.h> #include <X11/Xutil.h> int main(void) { (void) XCreateWindow(0,0,0,0,0,0,0,0,0,0,0,0); return 0; } cc /tmp/mplayer-conf-21693-4033.c -o /tmp/mplayer-conf-10428-4033.o -I/usr/X11R6/include -L/usr/X11R6/lib -lXext -lX11 -lnsl /usr/bin/ld: skipping incompatible /usr/X11R6/lib/libXext.so when searching for -lXext /usr/bin/ld: skipping incompatible /usr/X11R6/lib/libXext.a when searching for -lXext /usr/bin/ld: cannot find -lXext collect2: ld returned 1 exit status ldd /tmp/mplayer-conf-10428-4033.o ldd: /tmp/mplayer-conf-10428-4033.o: No such file or directory Result is: no ########################################## regards, kockkin ko
