I've been using CppUTest with g++ 4.7.2 for a while now without problems. However, I've just flipped the -std=c++11
option on so I can start using std::unique_ptr
and it fails immediately.
Even just compiling the main module:
#include <CppUTest/CommandLineTestRunner.h>
int main(int argc, char ** argv) {
return CommandLineTestRunner::RunAllTests(argc, argv);
}
fails with variations on:
In file included from /usr/include/CppUTest/TestHarness.h:77:0,
from /usr/include/CppUTest/CommandLineTestRunner.h:31,
from tests/testmain.cpp:15:
/usr/include/CppUTest/MemoryLeakWarningPlugin.h:56:53: error: declaration of ‘void* operator new(size_t) throw (std::bad_alloc)’ has a different exception specifier

from tests/testmain.cpp:15:
/usr/include/c++/4.7/new:93:7: error: from previous declaration ‘void* operator new(std::size_t)’
Removing the -std=c++11
option makes everything work just fine again.
The CppUTest documentation makes some comments about the macros conflicting with overloaded new operators, and suggests #including the standard headers first, but I get this problem without including any headers at all, although it looks like CppUTest/CommandLineTestRunner.h
is including <string>
itself.
Anyone come across this before or know what the issue is?
