I am compiling "gnome-core" package on HPUX box.
I've already compiled and installed "gnome-lib-1.0.55".
When i compile program, I get the compilation error as 
follow:


        gcc -DHAVE_CONFIG_H -I. -I. -I.. -I/opt/gtk+/include -I/usr/include/X11R6 -I/opt/glib/lib/glib/include -I/opt/glib/include

Stop.

When I checked the object file (gnome-edit.o) There is an error message;

"The editor you have chosen is probably either not available,
or is not on your current path."

But i didn't chose any editor!!!

Have you got any idea please??
