添加* .gcno和* .gcda文件使用CMake的

Question

我有類似的結構像這樣的項目使清潔規則：

├── CMakeLists.txt 
├── src 
│   ├── logic.cpp 
│   └── logic.h 
└── test 
    ├── CMakeLists.txt 
    └── logic_test.cpp 

主要CMakeLists.txt文件是：

cmake_minimum_required (VERSION 2.8) 
project (Logic) 
set (Logic_SOURCES ${PROJECT_SOURCE_DIR}/src/logic.cpp) 
include_directories (${PROJECT_SOURCE_DIR}/src) 
add_library (logic SHARED ${Logic_SOURCES}) 
add_subdirectory (test) 

而且CMakeLists.txt進行測試是：

find_package (GTest) 
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -O0 -g -march=native -mtune=native -fprofile-arcs -ftest-coverage") 
set (CMAKE_EXE_LINKER_FLAGS "-fprofile-arcs -ftest-coverage") 
set (Test_SOURCES ${Logic_SOURCES} ${PROJECT_SOURCE_DIR}/test/logic_test.cpp) 
add_executable (logic_test ${Test_SOURCES}) 
target_link_libraries (${TestName} gtest gtest_main gcov pthread) 

對於處理測試覆蓋率報告，我已經添加了cust OM目標爲test/CMakeLists.txt：

set (Coverage_REPORT ${PROJECT_BINARY_DIR}/coverage.info) 
set (Coverage_DIR ${PROJECT_BINARY_DIR}/coverage) 
add_custom_command (
    OUTPUT ${Coverage_REPORT} 
    COMMAND lcov -q -c -f -b . -d ${PROJECT_BINARY_DIR}/test -o ${Coverage_REPORT} 
    COMMAND lcov -e ${Coverage_REPORT} '${PROJECT_SOURCE_DIR}/src/*' -o ${Coverage_REPORT} 
    COMMAND genhtml ${Coverage_REPORT} --legend --demangle-cpp -f -q -o ${Coverage_DIR} 
    DEPENDS logic_test 
) 
add_custom_target (coverage DEPENDS ${Coverage_REPORT}) 

所有這些代碼工作正確的，符合市場預期。工作流程是這樣的：

mkdir build 
cd build 
cmake .. 
make 
./test/logictest 
make coverage 

但現在我想補充的測試覆蓋率文物的make clean規則。我曾嘗試這個代碼添加到test/CMakeLists.txt：

file (GLOB_RECURSE Test_GCNOS ${PROJECT_BINARY_DIR}/*.gcno) 
file (GLOB_RECURSE Test_GCDAS ${PROJECT_BINARY_DIR}/*.gcda) 
list (APPEND Test_COVERAGE_DATA "${Coverage_REPORT}") 
list (APPEND Test_COVERAGE_DATA "${Coverage_DIR}") 
list (APPEND Test_COVERAGE_DATA "${Coverage_GCNO}") 
list (APPEND Test_COVERAGE_DATA "${Coverage_GCDA}") 
set_directory_properties (PROPERTIES ADDITIONAL_MAKE_CLEAN_FILES "${Test_COVERAGE_DATA}") 

但預期（對我來說）這種方法是行不通的。當致電cmake .. artifatcs尚不存在時，變量Coverage_DATA爲空，因此運行測試後需要調用cmake ..。這看起來很醜（對我來說）。

所以我的問題是：如何將測試覆蓋率的工件添加到make clean規則？

這不能稱爲優雅的解決方案，但在我看來，它是更好，然後cmake回憶。 我試圖創建的宏，其通過源文件的列表確定覆蓋文物（*.gcno和*.gcda文件）的名稱：

macro (determine_coverage_data Sources TestName Artifacts Suffix) 
set (CoverageDirectory "${CMAKE_CURRENT_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/${TestName}.dir") 
foreach (File ${Sources}) 
    string (REGEX MATCH "^${CMAKE_CURRENT_SOURCE_DIR}*" Directory "${File}") 
    if (Directory STREQUAL CMAKE_CURRENT_SOURCE_DIR) 
     string (REGEX REPLACE "^${CMAKE_CURRENT_SOURCE_DIR}*" "${CoverageDirectory}" File "${File}") 
    else (Directory STREQUAL CMAKE_CURRENT_SOURCE_DIR) 
     string (REGEX REPLACE "/" ";" A "${CMAKE_CURRENT_SOURCE_DIR}") 
     string (REGEX REPLACE "/" ";" B "${File}") 
     list (LENGTH A DeepDirectory) 
     list (LENGTH B DeepFile) 
     set (File "${CoverageDirectory}") 
     set (I 1) 
     while (I LESS DeepDirectory) 
      list (GET A ${I} AI) 
      list (GET B ${I} BI) 
      if (AI STREQUAL BI) 
       math (EXPR I "${I} + 1") 
      else (AI STREQUAL BI) 
       math (EXPR DeepDiff "${DeepFile} - ${I} - 1") 
       while (DeepDiff GREATER 0) 
        set (File "${File}/__") 
        math (EXPR DeepDiff "${DeepDiff} - 1") 
       endwhile (DeepDiff GREATER 0) 
       while (I LESS DeepFile) 
        list (GET B ${I} BI) 
        set (File "${File}/${BI}") 
        math (EXPR I "${I} + 1") 
       endwhile (I LESS DeepFile) 
      endif (AI STREQUAL BI) 
     endwhile (I LESS DeepDirectory) 
    endif (Directory STREQUAL CMAKE_CURRENT_SOURCE_DIR) 
    set (${Artifacts} ${${Artifacts}} "${File}${Suffix}") 
endforeach (File) 
endmacro (determine_coverage_data) 

所以，完整的解決方案是看起來像：

├── cmake 
│   └── UseGCov.cmake 
├── CMakeLists.txt 
├── src 
│   ├── logic.cpp 
│   └── logic.h 
└── test 
    ├── CMakeLists.txt 
    └── logic_test.cpp 

主要CMakeLists.txt文件是：

cmake_minimum_required (VERSION 2.8) 
project (Logic) 
set (Logic_SOURCES ${PROJECT_SOURCE_DIR}/src/logic.cpp) 
# Include macro. 
include ("${PROJECT_SOURCE_DIR}/cmake/UseGCov.cmake") 
include_directories (${PROJECT_SOURCE_DIR}/src) 
add_library (logic SHARED ${Logic_SOURCES}) 
add_subdirectory (test) 

而且CMakeLists.txt的測試是：

find_package (GTest) 

set (Test_SOURCES ${Logic_SOURCES} ${PROJECT_SOURCE_DIR}/test/logic_test.cpp) 
set (TestName logic_test) 

set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -O0 -g -march=native -mtune=native -fprofile-arcs -ftest-coverage") 
set (CMAKE_EXE_LINKER_FLAGS "-fprofile-arcs -ftest-coverage") 

# Call macro. 
determine_coverage_data ("${Test_SOURCES}" "${TestName}" Test_GCNOS ".gcno") 
determine_coverage_data ("${Test_SOURCES}" "${TestName}" Test_GCDAS ".gcda") 

set (Coverage_REPORT ${PROJECT_BINARY_DIR}/coverage.info) 
set (Coverage_DIR ${PROJECT_BINARY_DIR}/coverage) 
add_custom_command (
    OUTPUT ${Coverage_REPORT} 
    COMMAND lcov -q -c -f -b . -d ${PROJECT_BINARY_DIR}/test -o ${Coverage_REPORT} 
    COMMAND lcov -e ${Coverage_REPORT} '${PROJECT_SOURCE_DIR}/src/*' -o ${Coverage_REPORT} 
    COMMAND genhtml ${Coverage_REPORT} --legend --demangle-cpp -f -q -o ${Coverage_DIR} 
    DEPENDS logic_test 
) 
add_custom_target (coverage DEPENDS ${Coverage_REPORT}) 

set (Test_COVERAGE_DATA ${Coverage_REPORT} ${Coverage_DIR} ${Test_GCNOS} ${Test_GCDAS}) 
set_directory_properties (PROPERTIES ADDITIONAL_MAKE_CLEAN_FILES "${Test_COVERAGE_DATA}") 
add_executable (${TestName} ${Test_SOURCES}) 
target_link_libraries (${TestName} gtest gtest_main gcov pthread) 

Answer 2

我已經寫了代碼覆蓋率CMake的腳本，很容易與http://coveralls.io/一起使用，如果你正在做的一個開源項目：

https://github.com/JoakimSoderberg/coveralls-cmake https://github.com/JoakimSoderberg/coveralls-cmake-example

但是，如果你想有一個腳本只需在本地生成覆蓋率數據即可獲得此項目：

https://github.com/bilke/cmake-modules/blob/master/CodeCoverage.cmake

我解決了清理覆蓋率數據的問題，方法是先生成新覆蓋數據，然後在覆蓋目標中刪除它。這不是一個使清潔解決方案，但工作得很好：

file(REMOVE_RECURSE ${PROJECT_BINARY_DIR}/*.gcda) 

（我幾乎從來不使用使清潔而是多個構建迪爾斯和偶爾rm -rf *使清潔的整個概念在我看來破碎，具有堆積和源單獨使事情更清潔）
