If the command lablgtk2 works (without being preceded by a full path to the=
=20
command), it means that lablgtk2 is installed in your system (on unix it=20
means that this program is located in one of the directory contained in the=
=20
environment variable $PATH, probably /usr/bin so /usr/bin/lablgtk2). So in=
=20
the command line to compile you shouldn't use -I ../src but -I +lablgtk2
The '+' sign replaces the base path of the installed ocaml libraries, so=20
+lablgtk2 stands for /usr/lib/ocaml/lablgtk2
so your full command line should be:
ocamlc -g -I +lablgtk2 lablgtk.cma about.ml -o about
The path ../src is for when the library is not installed, but just compiled=
 in=20
this relative directory.
