Re: Extern/scope issue

[DLearner via Digitalmars-d-learn]

The __gshared is irrelevant to it working between modules, but it is relevant if you want C compatibility between threads (NOTE: extern(C) sets mangling, otherwise the module would be encoded in its name).

Solved:
The following produces the expected result.
However, changing extern(C) to extern(D) causes linker failures.
To me, that is bizarre.
Testmain:
extern(C) int xvar;
import testmod;
void main() {
   import std.stdio;

   writeln("Entering: main");
   xvar = 1;
   writeln("xvar=", xvar);
   testsub();
   writeln("xvar=", xvar);

   writeln("Leaving: main");
}

Testmod:
extern extern(C) int xvar;
void testsub() {

   import std.stdio;

   writeln("Entering: testsub");
   writeln("xvar=", xvar);
   xvar = 2;
   writeln("xvar=", xvar);
   writeln("Leaving: testsub");
}
