The simplest test case that I can think of is something like this:
$P0 = box 1
loadlib "test_lib_1", $P0
loadlib "test_lib_2"
# If we get this far, it worked
test_lib_1.c
SOMEHOW_EXPORT_FROM_SOLIB void test_symbol(void) {}
test_lib_2.c
SOMEHOW_IMPORT_FROM("test_lib_1" /* iirc windows uses a two-level namespace
symbols, making RTLD_GLOBAL unneccessary. */)
extern void test_symbol(void);
SOMEHOW_EXPORT_FROM_SOLIB void dont_optimize_me_out(void) {
test_symbol();
}
...but I have no idea how to put this into reality.
