I'm attempting to integrate googlemock into my tests. I had already successfully built and run tests on googletest, and now am trying to incrementally add the gmock functionality into the tests as well, but I've hit a compile error that I utterly do not understand.

I am not attempting to use or define mocked classes, or use anything gmock.h provides. At the top of my (previously working) tests.cpp file I merely type

#include "gmock/gmock.h"

And I get the compile error:

gmock/gmock-matchers.h(2497) : error C2059: syntax error : 'sizeof'

gmock/gmock-matchers.h(2505) : see reference to class template instantiation 'testing::internal::ElementsAreMatcherImpl' being compiled

gmock/gmock-matchers.h(2497) : error C2059: syntax error : ')'

gmock/gmock-matchers.h(2497) : error C2143: syntax error : missing ')' before '{'

gmock/gmock-matchers.h(2497) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

gmock/gmock-matchers.h(2499) : warning C4183: 'Message': missing return type; assumed to be a member function returning 'int'

I'm compiling this using nmake/vc++ on Windows 7, and I can't fathom why I would get these compile errors simply from adding the core gmock include file to my test file. Has anyone seen this sort of thing before?

  • I remember something about the order of includes being important? have you tried putting gmock.h before and/or after gtest.h ? – Kyle C May 24 '12 at 16:19
  • Yeah, I've tried varying the #include order but received the same error. – whazzmaster May 24 '12 at 16:32
  • Why you want to include gmock.h at all in a test-file? It should be sufficient to include your Mock to your testfile. Does it work for you, if you create a Fixture.h which is included by the testfile, and to include gmock.h in this fixture? – Alex Sep 07 '12 at 15:13
  • @whazzmaster: I am also getting the same error. How did you resolve it? – NJMR Mar 14 '16 at 04:32

  1. Did you init google mock with InitGoogleMock(&__argc, __argv) in test project's main function?
  2. You should include only "gmock/gmock.h" in your test files (and where you call InitGoogleMock) - no need for inclusion of gtest.h.
  3. Have you updated your googletest library to googlemock. (https://github.com/google/googletest)

If all the things above are true it should work.

Things to make sure before using gtest and gmock.

  1. Include the gmock lib in Android.bp file.
  2. Include the header "external/googletest/googlemock/include" in include_dirs in Andoird.bp.
  3. Initialize the gmock and gtest in your test main function.
    testing::InitGoogleTest(&argc, argv);
    testing::InitGoogleMock(&argc, argv);

  • This code-only answer doesn't attempt to answer the question at all? The issue comes from _including `gmock.h`_ -- and all this answer is doing is showing an example of... some really unrelated code with duplicate symbols? I'm recommending for deletion; I have no idea what this even is. – Human-Compiler Aug 05 '22 at 21:23
