OK, this is getting interesting. Here are the issues noticed, and
their resolution:

* gschem wants /etc/ld.so.conf to have a link to /usr/local/lib in
it. I am suprised that it is not in RH9, but I'll take your word for
it. Yes, I know that RH puts all it's stuff in /usr/lib & most GNU
goes by default into /usr/local/lib. They each adhere to a different
standard -- there are so many to choose from!

We will look at checking & setting LD_LIBRARY_PATH to include
/usr/local/lib when the setup program runs.

* pkg-config. Pkg-config is a configuration utility which reports
back info about what compile and load flags should be set when
building a package. It is not new, nor specific to any distribution.
It's used by configure and make when doing a build. I think it was
introduced by the gtk folks themselves. Here's an example
run, for a totally random package, openssl:

[sdb@localhost /etc]$ pkg-config openssl --cflags
-I/usr/kerberos/include

It returns the compiler flag -I/usr/kerberos/include, which tells gcc
where to find my kerberos/include stuff.

Pkg-config should live on your system too. It calls the gtk2 stuff
"gtk+-2.0", and returns the following:

[sdb@localhost /etc]$ pkg-config gtk+-2.0 --cflags
-I/usr//include/gtk-2.0 -I/usr//lib/gtk-2.0/include
-I/usr/X11R6/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0
-I/usr/include/freetype2 -I/usr//include/glib-2.0
-I/usr//lib/glib-2.0/include

Try that out on your system too. You should get a similar result.

Anyway, I think you and Ales are having a nomenclature disagreement.
The RPM calls it gtk2, but pkg-config (which is used in configuring
and making gEDA) calls it gtk+-2.0.

* Symbols. The installer *did* run to it's end once you left it
alone. We agree that there was a dependency issue causing each
gEDA/gaf program to remake the symbols as it built each program in
sequence. Next time, just relax and let it build.

How long did you let it spin before you pulled the plug, anyway? A
typical install session with the CD can run 1 -- 2 hours, depending
upon the speed of the machine.

* Installing into /usr/local/bin. Actually, for the installer, I
recommend installing your sources into /usr/local/src/geda-sources,
(maybe geda-sources-20041228, or whatever version you use) and
installing your executables into /usr/local/geda. Then put
/usr/local/geda into your $PATH. That way you can nuke it if you ever
need to.

: 18 days isn't all that long. Have you heard of any *new* users that

: bit of information.

We have tested this new installer on several machines with several
people, but they all knew what they were doing (gEDA-wise, that is).
A total newbie install is the experiment we are running on you.
