[Asterisk-Users] Compile Problem

[jna]

I am trying to compile the asterisk and if fails at the end on:   make[1]: Entering directory `/usr/src/asterisk-0.5.0/pbx' gcc -shared -Xlinker -x -o pbx_gtkconsole.so pbx_gtkconsole.o `gtk-config --libs gthread` /usr/lib/gcc-lib/i486-slackware-linux/3.3.2/../../../../i486-slackware-linux/bin/ld: cannot find -lXext collect2: ld returned 1 exit status make[1]: *** [pbx_gtkconsole.so] Error 1 make[1]: Leaving directory `/usr/src/asterisk-0.5.0/pbx' make: *** [subdirs] Error 1   Anyone know what is wrong? Linpri and zaptel compiled just fine. This is linux slackware 2.4.23 all the latest from 9.1 slackware distrib fresh system install.   Thanks, John
