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，并且我能够使用 CoverStory 查看结果。
但是，当我尝试使用 gcovr 生成报告时，什么也没有生成。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。
此处提出了类似的问题Gcovr 为 0 个文件生成覆盖率数据，但尚未发布解决方案。我已经提供了更多细节，希望能得到答复。
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 .
