Exactly! (I can't believe I'm starting to get the hang of this...) But
what we ultimately need is true dynamic loading of never-seen modules.
After the initial test I tried to load symbols with dlopen(). Indeed
this works:
auto p = dlopen("liblib.so", RTLD_LAZY);
And it does work, all fine. To my dismay, as soon as I removed the flag
"-llib" from the linker command line in the makefile, dlopen() didn't
want to work anymore.
So I think in order to enable "true" dynamic loading, I'll need to
generate PIC for druntime and phobos, and then link liblib.so like this:
dmd -fPIC -c lib.d
gcc -shared lib.o -o liblib.so -L/path/to/phobos -lphobos2
Is that correct?
At that point, of course, a variety of issues will need to be resolved
as people pointed out.
