Hi all,

I am doing some C / C++ programming in cygwin and I notice when I add
something to my path then try to compile, the gcc / g++ compiler
cannot find some files, even though they are in the directory I may
have just added to my path.

For example I have copied the example program from http://www.gtk.org/tutorial/c39
.html
and when I compiled it, the compiler couldn't find gtk/gtk.h.

I thought to solve this I would have to add the path to gtk/gtk.h to
my path and so I did;

> PATH=$PATH:/usr/include/gtk-2.0

then I compiled again and while it found gtk.h it could not find a lot
of other gtk headers, such as gtktext.h.  However this and the other
files which were not found are also in /usr/include/gtk-2.0 and they
are included as <gtk/gtktext.h>.

I'm guessing that my path has not been set right but I'm fumbling in
the dark.  If someone could help it would be greatly appreciated.

John

The compiler doesn't search the directories in the PATH
variable. These are searched by the *shell* to start
commands.

You tell the compiler where the include files are when you
invoke it. gcc uses the -I option. Check your compiler's
documentation otherwise.

That is a very bad way to describe a problem. Always include
the exact command you entered and the exact error message
you got, not *descriptions* of them.
