无法让 gcovr 生成覆盖率数据

Question

使用 gcovr 3.2 我正在尝试为我使用 Xcode 5.0 开发和运行的一组单元测试生成代码覆盖率报告。

我已成功配置 Xcode 以在执行测试后生成 .gcda 文件，并且我可以使用 CoverStory 查看结果。

但是，当我尝试使用 gcovr 生成报告时，没有生成任何内容。打开详细开关后，我可以看到它扫描目录中的 gcda/gcno 文件并找到我期望的文件。我尝试了各种开关并将文件放在不同的目录中，但没有任何运气。

在这里Gcovr generates coverage data for 0 files 提出了类似的问题，但没有发布任何解决方案。我已经提供了更多细节，希望能得到回复。

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 .

Scanning directory . for gcda/gcno files...
Found 2 files (and will process 1)

Answer 1

对于任何可能感兴趣的人，我最终想通了。

从目录 /Users/Test/development 我输入了以下命令：

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。在我之前的尝试中似乎找不到源文件。
