GoogleTest rename class not working in Visual Studio 2012

I have the following enum class:

enum class Message : qint8 {INFO = 0, WARNING = 1, NON_FATAL_ERROR = 2, FATAL_ERROR = 3, DEBUG_INFO = 4};

and when I run the following code with Google Test (issued from SVN):

EXPECT_NO_THROW(
     for(qint32 i = 0; i < 10; ++i)
         logger->onIncomingMessage(mapper::Message::INFO, "Testing logging system")
);

The onIncomingMessage function signature:

 void onIncomingMessage(const mapper::Message &type, const QString &report);

Visual Studio 2012 contains the following exceptions:

Error   1   error LNK2001: unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > testing::FLAGS_gtest_death_test_style" (?FLAGS_gtest_death_test_style@testing@@3V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@A) C:\Users\Michele\Projects\occupancymapper\build\Modules\Core\test_logger.obj

Error   2   error LNK1120: 1 unresolved externals   C:\Users\Michele\Projects\occupancymapper\build\Modules\Core\Debug\logger.exe   1

Without GoogleTests, the code in my class works fine, but when using GoogleTest it doesn't. On Linux, it works fine.

I already applied the VARIADIC_MAX value (set to 10) as suggested here in a similar question on StackOverflow question but it doesn't work. What am I doing wrong?

I solved the problem. In my test case, I added the following:

::testing::FLAGS_gtest_death_test_style = "threadsafe";

right after



::testing::InitGoogleTest(&argc, argv);

because under Linux it was giving me problems.

Removing this line under MSVC, fixing the problem and compiling.

It looks like the error has nothing to do with the enum class - these are IntelliSense (code editor) errors, not the compiler.



The real problem is that the linker cannot find the "testing: FLAGS_gtest_death_test_style" symbol. Have you specified a .lib file for the link? Have you build a google test library with the same code generation and debug level settings ( this discussion might be helpful).
