[Chicken-users] Help compiling and using an egg

[Alejandro Forero Cuervo]

Hi.

I am in the process of creating an egg to wrap the code provided
by Subversion's svn_client, which some of my programs use.  All
the code is in my svn-client.scm file and I have the following
svn-client.setup file:

> (run (csc -s -O2 -d0 svn-client.scm -C`apr-config --includes` -L 
> |"`apr-config --libs --link-ld`"| -L -lsvn_client-1 -C 
> -I/usr/include/subversion-1))
> (install-extension 'svn-client '("svn-client.so"))

I had to use double quotes around the output of ``apr-config
--libs --link-id'' since it includes many options (which would
otherwise confuse csc).

The module is successfully built:

However, I can't seem to load it:

> #;1> (use svn-client)
> ; loading /mnt/matrix/stow/chicken-1.66/lib/chicken/svn-client.so ...

Doing ``ldd svn-client.so'' shows no signs of problems:

Any ideas on what could be wrong?  Perhaps (load) should produce a
more detailed output explaining why it failed?

Any help would be greatly appreciated!
