[erlang-questions] Linking enif_* functions to an executable file

Hello,
I am having trouble to debug a NIF library that I wrote (and somehow I
cannot make gcc to stop when a crash happens in it).
So I would like to test the NIF in an executable like this:
static ERL_NIF_TERM nif_myfunc(ErlNifEnv *env, int argc, const ERL_NIF_TERM
argv[]) {
... do something with enif and native functions ...
}
void main() {
ErlNifEnv *env = enif_alloc_env();
nif_myfunc(env, 0, 0);
}
But it seems enif_alloc_env is not present in any lib*.a or *.so that gets
generated when I build erlang.
I tried to link to the beam (renamed as libbeam.a)) but i got the linker to
segfault. So I might need to extract these definitions or extract them from
the beam source code and add it to my app, but it looks too much trouble.
So, is there a simple way I can do this?
Regards,
Takeshi
