I have been reading both of your messages. ECL is not prepared, currently, to 
be arbitrarily linked into a C program. The linking phase has to be performed 
by ECL. I placed some examples both in the mailing list and in the manual. 
Basically, you have to use c:build-program providing it with the names of the 
lisp and C libraries (this includes your C code) that you want to include. 
Maybe that is the cause of the problem, because eval(...) should return the 
output of the function.
