Just encountered this compilation failure in DMD winx64 2.096,
which previously worked in 2.095 and prior versions. Just
wondering if it's a bug, or a new issue to keep in mind when
importing modules? Sorry for the complex nature of this scenario
but I'll try to keep it as simple as possible.
Given the following 4-file setup:
// main.d
import cream;
void main() {}
// cream/package.d
module cream;
public import cream.dcream;
public import cream.callbacks;
// cream/callbacks.d
module cream.callbacks;
import cream;
extern(C++) class CallbackBase {}
// cream/dcream.d
module cream.dcream;
import cream;
import std.container.array;
Array!CallbackBase callbackTracker;
Compilation fails with the following error:
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container\array.d(519): Error:
incompatible types for array comparison: `const(CallbackBase[])` and
`const(CallbackBase[])`
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container\array.d(189): Error:
template instance `std.container.array.RangeT!(const(Array!(CallbackBase)))`
error instantiating
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container\array.d(528):
instantiated from here: `RangeT!(Array!(CallbackBase))`
cream\dcream.d(4): instantiated from here:
`Array!(CallbackBase)`
It seems I can fix this by changing the order the other modules
are imported in package.d like so:
// cream/package.d
module cream;
public import cream.callbacks;
public import cream.dcream;
I'm curious why this worked in prior dmd versions, and if it's
something I'll need to worry about going forward when creating
complex multi-file modules.
