使用lcov源代碼文件的代碼覆蓋

Question

我正在使用lcov和genhtml生成代碼覆蓋率報告。通過以下目錄結構，我可以獲得位於tests /目錄中的源文件的代碼覆蓋範圍，但無法獲取我的src /目錄中my_file.c文件的代碼覆蓋範圍。

src/ 
    my_file.c 
    my_file.h 
tests/ 
    AllTests.c 
    CuTest.c 
    CuTest.h 
    my_file_tests.c 

    objects/ 
     AllTests.gcda 
     AllTests.gcno 
     AllTests.o 
     CuTest.gcda 
     CuTest.gcno 
     CuTest.o 
     my_file.gcda 
     my_file.gcno 
     my_file.o 
     my_file_tests.gcda 
     my_file_tests.gcno 
     my_file_tests.o 

從測試目錄調用LCOV命令：

lcov -b . --directory objects/ -c -o ./coverage/app.info

升級從LCOV 1.7至1.9修復了這個問題對我來說。版本1.9可從http://ltp.sourceforge.net/coverage/lcov.php
