In article <1993Jan21.004406.6508@informix.com>  I asked for help
regarding why, after finally getting a clean compile of gcc-2.3.3 the
compiler was unable to automatically find <iostream.h>; I was forced
to supply the directory in the -I option to g++.  When I did this the
compile completed the linker (or more accurately, collect) complained 
it was unable to find libg++.a (library for -lg++).  I got back some
important answers:

Mr. DM and AG (names witheld to protect their mailboxes ;) both replied
that I had needed to supply a --prefix parameter to the configure
command for both gcc and libg++.  Furthermore, the target directory
must be the same for both configure commands.

Unfortunately, this is documented only in the libg++ README, not in
the gcc readme (I just ran a grep on it; it isn't there!) and I really
had used the --prefix in the configure on gcc.  SHort of going through
all that building again (remembering to drop the -g from all Makefiles
and uncommenting/commenting for various models! UGH!)  what can I do
to make use of everything where it is?

Mr. JO to the partial rescue:  Here is his reply:

>I set up libg++ on decstation 5000/240 running Ultrix 4.?
>To search the various files the following env var are needed (for me)
>COMPILER_PATH (sound ok for you)
>LIBRARY_PATH  ( I think you need this )
>CPLUS_INCLUDE_PATH ( for includes )

Well, I set up the CPLUS_INCLUDE_PATH to reference where I had put
the include directory: /usr/gnu/lib/g++-include .. This helped it find
the <iostream.h> without my supplying the -I switch to g++.  However
the LIBRARY_PATH did not help the linker (or collect) find libg++.a,
no matter where I aimed it.  BTW, the directory gcc-lib is under
/usr/local/lib.

Thanks to all who sent me the help so far.  I'm almost there with only
one screw-up along the way.

C'mon Netters, please help hack my way around that screw-up!  As
before, please reply be e-mail.

Thanks again.
