Project with no RTTI

My c++ project compiles with the flag -fno-rtti set (the development
is made under MacOS X with XCode).

When I compile the tests, I got the following error: "error: cannot
use typeid with -fno-rtti"

I also defined the variable GTEST_HAS_RTTI to 0 to disable the RTTI.

What is missing in my project configuration ?

Which version of gtest are you using? Can you find GTEST_HAS_RTTI in
include/gtest/internal/gtest-port.h?

I use the "trunk" version (recompiled).
I can find the GTEST_HAS_RTTI in the header file you specified.

How did you set GTEST_HAS_RTTI to 0? Was the setting applied to the
tests you were compiling? What is the exact error message?

I passed the option -DGTEST_HAS_RTTI=0 to gcc and I also put a
"#define GTEST_HAS_RTTI 0" line in the file I am compiling.

The error message returned by the compiler is:

"error: cannot use typeid with -fno-rtti"

Is the error in gtest's code or your code? Could you please provide
the source code that triggers this error and let's know which line
caused the error?

Here's the code that is failing:

/* main.cc */

#define GTEST_HAS_RTTI 0
#include <gtest/gtest.h>

#if GTEST_HAS_RTTI
#error Gtest should not have RTTI enabled
#endif

/*
int main(int argc, char **argv)
{
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
*/

It's just the include of gtest header file that is failing.

The errors come from the following standard header files:
functional
functional_iterate.h

I think you ran into a bug in the version of gcc used in Xcode, namely
that tr1/functional doesn't work with -fno-rtti (it should).

gtest doesn't use tr1/functional. However, its Combine() function
(for value-parameterized tests) use tr1/tuple, whose implementation
happens to pull in tr1/functional (that's how gcc implements it).

I think you can workaround the problem by preventing gtest from
including tr1/tuple. The only functionality you'll lose is Combine(),
which is rarely needed. To do that, just define GTEST_HAS_TR1_TUPLE
to 0. Please let me know if that works.

If this indeed fixes it, we can add logic to gtest to do this
automatically.

Ok Thanks,
I added the -DGTEST_HAS_TR1_TUPLE=0 to the compiler options and it now
works.
