Okay, that makes sense :)  I hope Walter introduces a name mangling specification and vtbl format etc... so that the same problems don't befall D :)

Too late... :-P

Already have to build two different libs: one for GDC, one for DMD.
(different ABI, different Phobos). It seems only "C" is constant*...

Well, not as lucky on my part. Recompiled wxd as per instructions but get this one:

make CXX="g++ -D__GDC__" DMD="gdmd" -C Samples
make -C Controls
gdc -c -O2 -I../.. Controls.d
gdc -o ../../bin/Controls Controls.o -L../.. -lwxd -lwxc `wx-config --libs` -lstdc++
/usr/bin/ld: Undefined symbols:
typeinfo for wxThread
 ... <SNIP> ...
typeinfo for wxNumberEntryDialog
collect2: ld returned 1 exit status
make[2]: *** [../../bin/Controls] Error 1

Must wxWidgets be recompiled as well?

Yes, you must compile wxWidgets with the same C++ version as "wxc"
(this is because C++ can't link code from two different versions...)

You can use e.g. "g++-3.3" and "g++-4.0" as the CXX compiler names.

It is compiled with the same version. First I compiled wxWidgets, and then wxd, it failed on Tiger, so I recompiled wxd without -lcc_dynamic, and got this error.

So what I meant is if I need to recompile wxWidgets as well, as part of the "Tiger fix"?

They're not *really* related.

The addition of libgcc.a (via the symlink libcc_dynamic.a -> /usr/lib/gcc/darwin/default/libgcc.a) was done in order to fix
the link errors "restFP" and "saveFP", when compiling on Panther.
(like this: http://nxg.me.uk/note/2004/restFP/)

What it says is that it isn't able to find the C++ typeinfo,
which I saw when I was trying to run G++-3.3 progs with G++-4.0...

Maybe it's some other error in your case ?
You could try compiling wxWidgets dynamically ?

I, on the other hand, am eagerly waiting for this QT-wrapper. Qt is a quality product (much better code than GTK+) and the license alternatives aren't that bad for home users and bigger enterprises.

Does wxD have cross-platform OpenGL support?  If not, when?

If you port Qt to D you will be my hero forever.

There *is* support in wxWidgets for OpenGL (wxGLCanvas), and
there is support in D for using OpenGL - but not in wxD yet.


Mostly because it wasn't in wx.NET version 0.7.2, actually...

If anyone wants to write the needed wrappers for wxc / wxd,
we'd be more than happy to include them in wxD of course :-)
