如何正确包含我自己的标头?

CMake How to properly include my own headers?

本文关键字：自己的 何正确 包含我      更新时间：2023-10-16

我正在使用ros，现在我想编写自己的unittest。但我正在为此苦苦挣扎。也许你对我有什么建议？或者也许是一个解决方案？

my structure:
-catkin_ws
--build
--install
--src
----project1
----CMakeLists.txt
----package.xml
------include
--------prime_tables.h
--------sample1.h
------src
--------sample1.cpp
------tests
--------sample1_unittest.cpp

我的清单.txt：

cmake_minimum_required(VERSION 2.8.3)
project(project1)
find_package(catkin REQUIRED COMPONENTS roscpp rostest rosunit)
find_package(sample1)

catkin_package(
INCLUDE_DIRS include
LIBRARIES ${PROJECT_NAME}
CATKIN_DEPENDS roscpp rostest
DEPENDS  )
include_directories(include ${catkin_INCLUDE_DIRS})

if (CATKIN_ENABLE_TESTING)
catkin_add_gtest(project1 tests/sample1_unittest.cpp)
add_executable(add_test tests/sample1_unittest.cpp)
add_library(add include/sample1.h src/sample1.cpp)
target_link_libraries(add_test ${catkin_LIBRARIES})
target_link_libraries(add_test gtest)
target_link_libraries(add_test prime_tables)
target_link_libraries(add_test sample1)
endif()

我收到此错误：

[87%] Linking CXX exectuable
/usr/bin/ld -lprime_tables cannot find
/usr/bin/ld -lsample1 cannot find

问题出在哪里？你提一下，我对CMake不是很熟悉。

sample1.cpp你想要并测试一个库，你想创建一个链接到这个库并运行单元测试的可执行文件？

一些基本的cmake信息：add_library、add_executable和target_link_libraries的第一个参数是库/可执行文件的名称。因此，如果将链接库指定到此库或可执行文件，则必须再次使用此名称。

并在此处查看更多信息： http://wiki.ros.org/catkin/CMakeLists.txt http://docs.ros.org/jade/api/catkin/html/howto/format2/gtest_configuration.html

我的猜测是，你想要这样的cmake：

cmake_minimum_required(VERSION 2.8.3)
project(project1)
catkin_package(
INCLUDE_DIRS include
LIBRARIES ${PROJECT_NAME}
CATKIN_DEPENDS roscpp rostest
DEPENDS
)
include_directories(include 
${catkin_INCLUDE_DIRS}
)
add_library(${PROJECT_NAME}_sample1 
src/sample1.cpp
)
target_link_libraries(
${PROJECT_NAME}_sample1
${catkin_LIBRARIES}
)
if (CATKIN_ENABLE_TESTING)
catkin_add_gtest(${PROJECT_NAME}_test 
tests/sample1_unittest.cpp
)
target_link_libraries(${PROJECT_NAME}_test 
${PROJECT_NAME}_sample1
${catkin_LIBRARIES}
)
endif()
