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.

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.

It's the framework Headers path that needs to go in User Header Search Paths e.g. ../../googletest/gtest.framework/Headers where ../.. is relative to your xcodeproj – Shaniceshanie

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();
   }

@mortond Thanks. I removed the broken link to the article. The article does not exist anymore so no use keeping it here. – Pediform

Try deleting the contents of your DerrivedData folder, and re-building.
