Hello!
Last night I was playing around with some of the postgres demos
in order to find out some things which are very interesting
for me.
Starting with circle.c I added further (graphical) functionality
to the output routine.
This made it necessary to link circle.o with a graphical lib.
And this is the point where I failed.
Using the load-command postgres either complains too few symbols,
when I have not linked circle.o with my lib;
or it complains about multiple defined symbols.
The problem I think is that some libs use symbols already used
with postgres; in my case e.g. 'circf' and others.
So, do you think there is a possibility to use an arbitrary lib
together with postgres?
Is the a possibility e.g. to link circle.o in a way, that internal
references are covered but only important symbols (circle_out) show
in the symboltable (some kind of a soft strip)?
I tried these things with postgres 4.2 on a linux system, but the
will arise anywhere, I think.
Thanks for any help,
- Joerg

There is no easy answer to your question. A few possibilities:
- If only a few symbols are in your way, write sed scripts, which
replace them with something different. Eg.:
s/\(^|[^a-zA-Z_0-9]\)circf\($|[^a-zA-Z_0-9]\)/PG_&/g
and apply them to all affected files of the source tree.
- Get the "binutils" source code (from the GCC/src directory
of almost any linux ftp server) and hack the "strip" command
so it allows to specify a set of symbol names, which should
not be stripped.
