I am having hard time trying to install Google C++ Mocking Framework. I have successfully run sudo apt-get install google-mock. Then I tried to compile this sample file

#include "gmock/gmock.h"

int main(int argc, char** argv) {

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

  return RUN_ALL_TESTS();

}

with g++ -lgmock main.cpp and these errors have shown

main.cpp:(.text+0x1e): undefined reference to `testing::InitGoogleMock(int*, char**)'

main.cpp:(.text+0x23): undefined reference to `testing::UnitTest::GetInstance()'

main.cpp:(.text+0x2b): undefined reference to `testing::UnitTest::Run()'

collect2: error: ld returned 1 exit status

I guess the linker can not find the library files. Does anybody know how to fix this?

OK, I've now successfully started using gmock by building my own version as per the README provided with the source download from googlemock project website.

Get the download zip from the website:
http://code.google.com/p/googlemock/downloads/list

Unzip this to a directory, say ${GMOCK_ROOT}. Then, as per README instructions:

cd ${GMOCK_ROOT}

mkdir build

cd build

g++ -I../gtest/include -I../gtest -I../include -I.. -c ../gtest/src/gtest-all.cc

g++ -I../gtest/include -I../gtest -I../include -I.. -c ../src/gmock-all.cc

ar -rv libgmock.a gtest-all.o gmock-all.o

Thus you have your own libgmock.a in ${GMOCK_ROOT}/build. You actually also need pthreads to compile, so your compile command after that becomes:

g++ -I${GMOCK_ROOT}/include/ main.cpp -L${GMOCK_ROOT}/build -lgmock -lpthread
