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

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.
