Is that a limitation in DDT/CDT?

Quick question: with the current version is it possible to use it with a dub project at all (maybe via a manual project setup)?

I was trying to manually set it up, pointing "sources" as the source folder and trying to get the ~/.dub/packages into the list of libraries, but it did not seem to like it...

Yes, manual setup is possible, but you must use absolute path without `~`.

No, there's no inherent limitation in DDT/CDT regarding that.
But I was mistaken, that limitation I think is only for the GDB in the TDM-GCC suite:
"You can't use a 32-bit version of GDB to debug a 64-bit program. This is why the version of GDB provided with the TDM64 edition is a 64-bit-only program. You need to use a 32-bit version of GDB, such as the one provided by the MinGW.org project, to debug 32-bit programs."

I'm not sure how it is on GDB on Linux.

BTW, the CDT devs are contemplating supporting LLDB as well:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=405670
(primarily motivated by the poor support for GDB toolchain in Mac)

Nothing is decided or started yet, but it would be quite nice if they went for it, as then LLDB support could be trivially added to DDT as well. *fingers crossed*
Especially cool since the LDC compiler seems to be keeping up with DMD and being up to date better than GDC (this is just my impression, I haven't checked this claim)

On Mac OS X it's no problem. I can almost mix and match 32bit and 64bit willy-nilly.

Is it possible to use the GDB interface and invoke LLDB instead as the executable? Just to see what happens. They're supposed to be fairly compatible.

Check you claims. :o)


The only discrepancy as of writing is that Martin's work on shared library support is incompatible with, and currently blocking the 2.064 merge in GDC.

Exactly, although you can use some Eclipse resource variables in the path of linked folders.

Nah, the interface that GDB frontends use is an API for backends only called MI (Machine Interface). It's different from the console interpreter, and LLDB does not support that:
