Hello, I am trying to install ns-2.28 on Red Hat Enterprise Linux ES release 4.
First, when I run ./configure in otcl-1.9, it gives me this error: checking for X11 header files checking for X11 library archive *checking for XOpenDisplay in -lX11... no can't find X library* so I add the X11 library directory and run ./configure --x-libraries=/usr/X11R6/lib/ --x-includes=/usr/X11R6/include/ it passes the checking with a warning: checking for X11 header files checking for X11 library archive checking for libXext.a *warning: compiling without -lXext* Then I make, it says gcc -o otclsh -g -O2 -I. -I/srl/ns-allinone-2.28/include -I/srl/ns-allinone-2.28/include -I/usr/X11R6/include/ -I/include otclAppInit.c \ -L. -lotcl -L/srl/ns-allinone-2.28/lib -ltk8.4 -L/srl/ns-allinone-2.28/lib -ltcl8.4 -L/usr/X11R6/lib/ -lX11 -lnsl -ldl -lm */usr/bin/ld: cannot find -lX11* collect2: ld returned 1 exit status make: *** [otclsh] Error 1 Is this because I do not have libXext? Or anything else? Thank you in advance for your help. Best, Petra
