Re: [Chicken-users] Incremental compiling

[William Ramsay]

I put my list of files into a Makefile using the same code you gave 
below.   Make runs through each file and compiles it to an object file 
with no problem at all.   However, when I try to link it all together with 

csc -o foo a.o.b.o.c.o

I get all sorts of errors for multiple definitions of  C_toplevel and main.

How do I get past that hurtle?
