Gcovr生成0个文件的覆盖率数据 [英] Gcovr generates coverage data for 0 files

问题描述

我正在为iOS应用程序设置代码覆盖率.我正在使用XCode 5.0.2和gcovr 3.1来测试和执行iOS 7设备的代码覆盖率.最初，我在生成.gcda文件时遇到问题，但我遵循了此博客并解决了该问题

I am setting up code coverage for an iOS application. I am using XCode 5.0.2 and gcovr 3.1 to test and perform code coverage for iOS 7 devices. I initially had issues with .gcda file generation but I followed this blog and resolved the issue.

我仅对于调试模块将生成测试覆盖率文件"设置为是"，将仪器程序流"设置为是".我还在其他C标志"中为调试模块设置了-fprofile-arcs -ftest-coverage.当应用程序终止时，我已经在我的应用程序代码中添加了__gcov_flush().

I have set ‘Generate test coverage files’ to ‘Yes’, ‘Instrument Program flow’ to ‘Yes’ for the Debug module only. I have also set -fprofile-arcs -ftest-coverage for Debug module in ‘Other C Flags’. I have added __gcov_flush() in my app code when application terminates.

现在，生成的.gcda文件没有问题.

Now .gcda files are generating without issues.

然后将其复制到主目录中的工作区中.从工作区，我尝试为应用程序运行代码覆盖率.我从命令行执行gcovr命令，为我拥有的252个gdca文件传递了–object-directory和gcov命令.最后，我得到以下输出:

I then copy that to my workspace in my Home directory. From the workspace, I try to run code coverage for the application. I execute the gcovr command from the command line, passing –object-directory and gcov command runs for the 252 gdca files I have. In the end I get this output:

Gathered coverage data for 0 files

请帮助我解决问题.我已经花了很多时间浏览类似的问题，但是没有一个解决方案能解决这个问题.

Please help me in solving the issue. I have spent a lot of time browsing for similar issues but none of the solutions is working out.

推荐答案

我没有尝试将.gcda文件复制到其他地方，但是如果我cd到默认情况下生成gcda文件的目录，请使用没有参数，我得到有效的结果.也许这就是您需要做的?

I haven't tried copying the .gcda files elsewhere, but if I cd to the directory that the gcda files are generated in by default, then run gcovr with no arguments, I get valid results. Perhaps that's what you need to do?
