gtest.h file not found googletest xcode 7.0

Question

I'm trying to setup google testing framework for my c++ project following this guide in xcode 7.0 I got to the last step Build and Go but after hours of searching online I can't get my test project to run. The compiler does not seem to find the headers it needs. main.cpp:9:10: 'gtest/gtest.h' file not found. The source is:

#include "gtest/gtest.h"

#include "calc.hpp"

int main(int argc, const char * argv[]) {

    return 0;
}

I also tried #include <gtest/gtest.h> With same result.

Answer 1

Sometimes, Xcode cannot find header files in framework. You need additional steps to make it work.

• In build settings, complete Framework Search Paths with the path to your framework, which is gtest.framework.

• Add the framework path and to User Header Search Paths.

• If Xcode cannot find "gtest/internal/gtest-port-arch.h", you can find it in source folder "googletest/googletest/include". Add it to User Header Search Paths.

After these steps, gtest should work in Xcode 7.0.

Here is how I got it to work:

Steps:

1. Download the source code $ svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only

2. cd to the folder 'make' in the downloaded source code folder

3. run $ make gtest.a gtest_main.a
4. manually copy the two static library files to /usr/local/lib and copy the header file dir 'include/gtest' to /usr/local/include.
5. Add Header Search Path (/usr/local/include) and Library Search Path (/usr/local/lib) to your xcode’s project setting

6. Add linker flag agains gtest. In target setting under "Other Linker Flags". Add /usr/local/lib/gtest.a

   // main.cpp
   #include <stdio.h>
   #include "gtest/gtest.h"
   #include "calc.hpp" // has function int addition(int,int);
   TEST(MyFirstTest, TestAddition) {
           EXPECT_EQ(3, addition(1, 2));
   }
   GTEST_API_ int main(int argc, char **argv) {
           printf("Running main() from gtest_main.cc\n");
           testing::InitGoogleTest(&argc, argv);
           return RUN_ALL_TESTS();
   }
