I use qmake to generate .xcode file for my project and when I use XCode to build it, I get an error message: "/usr/lib/gcc/darwin/3.3/libstdc++.a(new_op.o) illegal reference to symbol: ___cxa_allocate_exception defined in indirectly referenced dynamic library /usr/lib/libstdc++.6.dylib".
I don't know why because I tried on another Mac OS X computer then it works fine.
Thankyou for helping.
