Some code snippets of what you try to do would help.
Maybe this example explain you something:
//mod.d
extern(C) int foo = 42;
void changeFoo(int val)
{
foo = val;
}
//main.d
import std.stdio;
import mod;
int main()
{
writeln(foo);
changeFoo(15);
writeln(foo);
return 0;
}
Compile:
dmd -H -c mod.d && //to generate .di file (not required)
dmd -shared mod.d -oflibmod.so && //to generate shared library
dmd -L-L. -L-lmod -L-rpath=. main.d //rpath is special argument
to linker, so executable will able to find shared library in
its directory. You can omit rpath, but then you must put your
.so file to one of standard directory like /usr/lib or
/usr/local/lib. That's all for Linux. On Windows you would have
different building steps.
Also probably you want to make your varialbe __gshared, so it
will not be thread-local. That's default D behavior to make all
global variables thread-local. And I don't know how other
languages will handle D thread-local variable.
Ahh I appreciate it, but I already have that part down and good.
:)
I was wondering about how to use export correctly, I apologize
for not being clear.
Also I'll keep in mind the __gshared, never even knew about it.
