GMock doesn't compile - GTEST_EXCLUSIVE_LOCK_REQUIRED seems to not be defined

Question

I'm trying to build a simple mocked class

#include "interpolation.hpp"

#include <gtest/gtest.h>
#include <gmock/gmock.h>

class MockInterp1D : public Interp1DBase {
public:
    MOCK_METHOD1(evaluateAt, double(double));
    MOCK_METHOD2(evaluateAt, double(double, int));
};

based on the following base class

class Interp1DBase {
public:
    virtual double evaluateAt(double) const = 0;
    virtual double evaluateAt(double, int) const = 0;
    virtual ~Interp1DBase() { };
};

using Google Mocks. When I try to compile the tests where this mock is used, I get the following error:

In file included from /usr/include/gmock/gmock-generated-function-mockers.h:43:0,
                 from /usr/include/gmock/gmock.h:61,
                 from /home/tlycken/exjobb/Code/alpha-orbit-follower/test/interpolation/interpolation-mocks.hpp:4,
                 from /home/tlycken/exjobb/Code/alpha-orbit-follower/test/physics/B-field-tests.hpp:6,
                 from /home/tlycken/exjobb/Code/alpha-orbit-follower/test/physics/B-field-tests.cpp:2:
/usr/include/gmock/gmock-spec-builders.h:134:41: error: expected ‘;’ at end of member declaration
   bool VerifyAndClearExpectationsLocked()
                                         ^

and then literally hundreds of similar syntax or definition errors all pointing to files within GMock.

I took a look at gmock-spec-builder.h:134, and found the following (in some context):

// Verifies that all expectations on this mock function have been
// satisfied.  Reports one or more Google Test non-fatal failures
// and returns false if not.
bool VerifyAndClearExpectationsLocked()
    GTEST_EXCLUSIVE_LOCK_REQUIRED_(g_gmock_mutex);

which led me to believe that GTEST_EXCLUSIVE_LOCK_REQUIRED_ might be a macro that for some reason wasn't defined. And indeed, after digging through all header files included from either gmock/gmock.h or gtest/gtest.h I still haven't found the definition of that macro.

What am I doing wrong here?

UPDATE:

I've been able to produce an even simple minimal example:

// in file mock-test.cpp
#include <gmock/gmock.h>
// Yeah, that's the only content

Compile with

g++ -o mock-test.o -c mock-test.cpp

Causes the same error.

I've installed GMock through sudo apt-get install google-mock, which gave me a folder under /usr/src where I could run cmake . followed by make to generate library files which I copied to /usr/lib. The header files were already in /usr/include so I didn't do anything about them manually.

I got the same error when I tried to compile using gmock 1.7 with gtest 1.6. Make sure you are using the same version of gtest.
