+(We need -pthread as Google Test and Google Mock use threads.)

 Next, you should compile your test source file with
 ${GTEST_DIR}/include and ${GMOCK_DIR}/include in the header search
 path, and link it with gmock and any other necessary libraries:
 
-  g++ -I${GTEST_DIR}/include -I${GMOCK_DIR}/include \
-      path/to/your_test.cc libgmock.a -o your_test
+  g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
+      -pthread path/to/your_test.cc libgmock.a -o your_test
 
 As an example, the make/ directory contains a Makefile that you can
 use to build Google Mock on systems where GNU make is available
