Trying to link in modules

[T. Kurt Bond]

I've got a module mymod in mymod.scm:

(module mymod (hello)

  (import scheme)

  (define (hello)

    (display "Hello, World, I'm in mymod!")

    (newline)))

and I've got a module trymod in trymod.scm:

(module trymod ()

  (import scheme)

  (import mymod)

  (hello)

  )

and when I compile them like this:

csc -s -J mymod.scm

csc -s mymod.import.scm

csc trymod.scm

it produces an executable trymod that runs and dynamically loads mymod.so, unloads it, and loads it again, then produces the expected output, calling the function hello in mymod as running it on macOS with DYLD_PRINT_LIBRARIES=YES ./trymod shows.

...

dyld: loaded: <59A8239F-C28A-3B59-B8FA-11340DC85EDC> /usr/lib/libc++.1.dylib

dyld: loaded: <EBB10A36-BF4E-3C83-9B63-9D26028D43B9> ./mymod.so

dyld: unloaded: <EBB10A36-BF4E-3C83-9B63-9D26028D43B9> ./mymod.so

dyld: loaded: <EBB10A36-BF4E-3C83-9B63-9D26028D43B9> ./mymod.so

Hello, World, I'm in mymod!

 However, I can't figure out how to do the same thing with mymod as non-shared objects.   I tried 

csc -c -J mymod.scm

csc -c mymod.import.scm

csc -static -o trymod.static mymod.o mymod.import.o trymod.scm

but I got

Undefined symbols for architecture x86_64:

  "_C_mymod_toplevel", referenced from:

      _f_138 in trymod.o

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Error: shell command terminated with non-zero exit status 256: 'clang' 'mymod.import.o' 'mymod.o' 'trymod.o' -o 'trymod.static' -m64 -L/usr/local/Cellar/chicken/5.2.0/lib /usr/local/Cellar/chicken/5.2.0/lib/libchicken.a -lm

What am I doing wrong?
