找不到 gtest.h 文件 googletest xcode 7.0

gtest.h file not found googletest xcode 7.0

提问by Allan Ojala

I'm trying to setup google testing framework for my c++ project following this guidein 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:

我正在尝试按照 xcode 7.0 中的本指南为我的 c++ 项目设置谷歌测试框架我到了最后一步 Build and Go 但是在网上搜索了几个小时后我无法运行我的测试项目。编译器似乎没有找到它需要的头文件。main.cpp:9:10: 找不到“gtest/gtest.h”文件。来源是：

#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.

我也试过 #include <gtest/gtest.h> 具有相同的结果。

Here is how I got it to work:

这是我让它工作的方式：

Steps:

脚步：

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

2. cdto 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();
   }
   

1. 下载源代码 $ svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only

2. cd到下载的源代码文件夹中的文件夹“make”

3. 跑 $ make gtest.a gtest_main.a
4. 手动将两个静态库文件复制到/usr/local/lib，将头文件目录'include/gtest'复制到/usr/local/include。
5. 将标题搜索路径 (/usr/local/include) 和库搜索路径 (/usr/local/lib) 添加到您的 xcode 项目设置

6. 在 gtest 中添加链接器标志。在“其他链接器标志”下的目标设置中。添加 /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();
   }

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

有时，Xcode 在框架中找不到头文件。您需要额外的步骤才能使其工作。

• In build settings, complete Framework Search Pathswith 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.

• 在构建设置中，使用您的框架路径完成框架搜索路径，即 gtest.framework。

• 将框架路径和添加到User Header Search Paths。

• 如果 Xcode 找不到“gtest/internal/gtest-port-arch.h”，您可以在源文件夹“googletest/googletest/include”中找到它。将其添加到User Header Search Paths。

After these steps, gtest should work in Xcode 7.0.

完成这些步骤后，gtest 应该可以在 Xcode 7.0 中运行了。

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

尝试删除 DerivedData 文件夹的内容，然后重新构建。
