test source file
OS: Mac OS X 10.8.2.
Architecture: x86_64.
Xcode: Xcode 4.6, Build version 4H127.
Clang version:
Apple LLVM version 4.2 (clang-425.0.24) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.2.0
Thread model: posix
The compilation of simple source file using rtti fails in a following way:
$ clang++ -c -O0 -std=c++0x test.cpp
$ clang++ -o test.exe -O0 -std=c++0x test.o
>Undefined symbols for architecture x86_64:
> "typeinfo for A", referenced from:
> f() in test.o
> typeinfo for B in test.o
>ld: symbol(s) not found for architecture x86_64
>clang++: error: linker command failed with exit code 1 (use -v to see
invocation)
$
The test complies with no error when using -fno-rtti option:
$ clang++ -c -O0 -std=c++0x -fno-rtti test.cpp
$ clang++ -o test.exe -O0 -std=c++0x -fno-rtti test.o
$
