Details:

Attached is a module fashioned after those currently generated by swig. It
uses a scheme wrapper that uses a module import with a rename to import a
module via an extension.

All code still works but the compiler compains that that module provided by
the load-extension does not exist

untar the attached archive and run make. The output I get from git master
is...

gcc -fpic -L/usr/local/include -c test-module.c 
gcc -shared test-module.o -o test-module.so 
LD_LIBRARY_PATH=. guile -L . test-script.scm
;;; note: autocompilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-autocompile argument to disable.
;;; compiling ./dir/mymodule.scm
;;; WARNING: compilation of ./dir/mymodule.scm failed:
;;; key misc-error, throw args (#f "~A ~S" ("no code for module" (dir
mymodule-prim)) #f)
see, it does still work: 32

The code has run and worked, the symbols are all there, but the compiler
still warns of "no code for module"

Follow-up Comment #1, bug #28442 (project guile):

A strace does show guile stat'ing for mymodule-prim(.scm), 

...
[pid  3056] stat64("./dir/mymodule-prim.scm", 0xbfcda24c) = -1 ENOENT (No
such file or directory)
[pid  3056] stat64("./dir/mymodule-prim", 0xbfcda24c) = -1 ENOENT (No such
file or directory)
[pid  3056] stat64("/usr/local/share/guile/1.9/dir/mymodule-prim.scm",
0xbfcda24c) = -1 ENOENT (No such file or directory)
[pid  3056] stat64("/usr/local/share/guile/1.9/dir/mymodule-prim",
0xbfcda24c) = -1 ENOENT (No such file or directory)

Follow-up Comment #2:

See discussion in http://article.gmane.org/gmane.lisp.guile.devel/9815.
Closing as invalid, as it appears that the module in question needs to have an
eval-when (or eval-case if 1.8 compatibility is needed). Thanks for the
report, and let us know if you have further problems.
