Hi, Im running slackware-current and am trying to compile mythtv. When I issue the make command I get the following error.

mythuser@nucleus:/tmp/mythtv-0.18.1$ make
g++ -Wl,-rpath,/usr/lib/qt/lib -o settings -L/usr/lib/qt/lib -lqt-mt -lXext -lX11 -lm -lpthread
/usr/lib/gcc-lib/i486-slackware-linux/3.3.4/../../../../i486-slackware-linux/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status
make: *** [settings] Error 1
mythuser@nucleus:/tmp/mythtv-0.18.1$


root@nucleus:/usr/X11R6/lib# ls -l *Xext*
-rw-r--r-- 1 root root 72964 2005-02-14 01:06 libXext.a

-rwxr-xr-x 1 root root 63316 2005-02-14 01:14 libXext.so.6.4*
root@nucleus:/usr/X11R6/lib#


the contents of /etc/ld.so.conf....
/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib/qt/lib

I have everything I need as far as I know and have no idea why this isnt compiling.

Thx in advance
