Re: [Gcl-devel] Interfacing C libraries and lisp.

[Camm Maguire]

Greetings!  Maybe try this, with your code in ff.lsp:


>(compile-file "ff.lsp")

Compiling ff.lsp.
End of Pass 1.  
End of Pass 2.  
OPTIMIZE levels: Safety=0 (No runtime error checking), Space=0, Speed=3
Finished compiling ff.lsp.
#p"ff.o"

>(load "ff.o")

Loading ff.o
start address -T 832c234 Finished loading ff.o
88

>(foobar "hello world")
hello world
NIL

-lc is linked into gcl already.  If you need another lib, let me know
 and I'll dig through the docs -- there is some lisp variable which
 adds libaries to the command line.

take care,
