hi all
we've now resoved the first problem; compiling David's example
objects works now.
Next we started to tinker with the source and adapt it to our needs;
it's not yet finished but we're already running into problems: the
initialiser of our collation makes use of functions such as fopen,
fseek, and fgetc..
We don't get that compiled; the linker complains about
these "unresolved" functions

The makefile is as follows:

Please, can someone help?
