Hey,

I'm playing around with a bit of OpenGL in D, and decided to add some physics. I choose Newton, but I'm having a few problems linking it.

When i compile i use:

dsss build -llNewton

It finds the file alright, but i get a TON of error like:

/usr/lib/gcc/i686-pc-linux-gnu/4.2.0/../../../libNewton.a(dgFile.o):(.gnu.linkonce.r._ZTI6dgFile[typeinfo for dgFile]+0x0): undefined reference to `vtable for __cxxabiv1::__class_type_info'

/usr/lib/gcc/i686-pc-linux-gnu/4.2.0/../../../libNewton.a(dgConvexCollision.o):(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'

I've kind a lost my head in this. Maybe it's just a small thing that i've forgotten, but i'm not sure what...

Hope someone got an idea.

Thanks,
Anders johnsen

Ohh yeah, forgot to say. I build the Newton.d file with htod from the Newton.h file.

Looks like Newton's written in C++.  Does it have a C interface?  Because if it uses a C++ interface, you're going to have to use BCD.gen, if anything, to bind to it.

I'm pretty sure it's C interface. At least it doesn't have any classes in the header(only structs).

Yes it's definitely C.  Htod is really not very smart.  It may have botched the translation.  I have Newton installed -- what was the command line you used for htod?  Straight up "htod Newton.h" just gave me errors.

Try linking with stdc++ (-llstdc++ ?)
