无法让gcovr生成覆盖率数据 [英] Can't get gcovr to generate coverage data

问题描述

使用gcovr 3.2，我试图为我使用Xcode 5.0开发和运行的一组单元测试生成代码覆盖率报告.

Using gcovr 3.2 I am trying to generate a code coverage report for a set unit tests that I have developed and run using Xcode 5.0.

在测试执行后，我已经成功配置了Xcode来生成.gcda文件，并且能够使用CoverStory查看结果.

I have successfully configured Xcode to generate the .gcda files following the execution of the tests and I am able to view the results using CoverStory.

但是，当我尝试使用gcovr生成报告时，什么也没有生成.启用详细开关后，我可以看到它扫描了目录中的gcda/gcno文件，并找到了我期望的目录.我尝试了各种开关，并将文件放在其他目录中没有任何运气.

However, when I try to generate a report using gcovr nothing is generated. With the verbose switch on I can see that it scans the directory for the gcda/gcno files and finds the one I'm expecting it to. I've tried various switches and putting the files in different directories without any luck.

此处提出了类似的问题 Gcovr生成了0个文件的覆盖率数据，但尚未发布解决方案.我提供了更多详细信息，希望能得到答复.

A similar question was asked here Gcovr generates coverage data for 0 files but no solution has been posted. I have provided more detail in the hope I get a response.

这是我得到的输出.

$ ls
t1-map.d    t1-map.dia  t1-map.gcda t1-map.gcno t1-map.o

$ gcovr -v -r .

推荐答案

对于任何有兴趣的人，我最终都知道了.

For anyone that might be interested I figured it out eventually.

从目录/Users/Test/development输入以下命令:

From the directory /Users/Test/development I entered the following command:

gcovr --html --html-details -o output-file-name.html -v -g -k -r ~/development/ .

源文件位于〜/development/"下的各个目录中.似乎在我较早的尝试中找不到源文件.

The source files are located in various directories under '~/development/'. It would appear that in my earlier attempts the source files could not be found.
