Hi all,

1. I made a static lib in C++ using the Lion standard compilers.
2. I made a static lib using dmd (which calls the C++ lib)
3. I made a testprogram that links against both libs

I get this answer from dmd:
Undefined symbols for architecture x86_64:
  "createQuicked()", referenced from:
      _D7quicked12_staticCtor1FZv in libRCF.a(quicked.o)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

Now the question:
Is it possible to use libs that have been compiled using the new clang based compilers on OSX from dmd?
Or is maybe something wrong in the scenario above?
Do I have f.e. to declare the c++ interface code in the main program?

thx in advance

It should work. DMD is compatible with GCC and Clang is compatible GCC so it should work. This is true for at least C, I'm not sure about C++. Are both the D and C++ code compiled for the same architecture?

Hi

Thank you for your help.
I wrapped some functions of Qt.
After updating to Qt5.0.1 it suddenly worked.

The lib is c++. Its probably a bit simple. but good to know that there is no problem with clang and dmd interop so far.

thx
