cmake(catkin_make) 自建库封装package

cmake(catkin_make) 自建库封装package

https://blog.csdn.net/convpool/article/details/87726649

以下为自建库封装过程，及用find_package 工具自动找到自建库头文件及库文件的完整过程。

1、新建链接库包

目录树如下

mylib

├── CMakeLists.txt
├── mylib
│ ├── mylib.cpp　
│ └── mylib.h
├── mylib-config.cmake.in　(便于find_package使用找到头文件位置和库位置)
└── package.xml

package.xml

ros　编译所需文件

<package format="2">
  <name>mylibname>
  <version>0.0.0version>

CMakeLists.txt

cmake_minimum_required(VERSION 2.8.12)
project(mylib) #工程名

#安装包内必须文件及文件夹
install(FILES package.xml DESTINATION share/mylib/)

#编译配置
add_library(mylib SHARED mylib/mylib.cpp)

set(TARGET_COMPILE_FLAGS "${TARGET_COMPILE_FLAGS} -std=c++11")
set_target_properties(mylib PROPERTIES
  COMPILE_FLAGS ${TARGET_COMPILE_FLAGS})

#安装相关文件
install(
  TARGETS mylib　#待安装库、可执行文件名
  EXPORT mylibExport #待输出安装配置文件　note 2
  ARCHIVE DESTINATION lib
  LIBRARY DESTINATION lib
  RUNTIME DESTINATION bin
)


# 安装头文件
file(GLOB_RECURSE hdrs "*.h")

foreach(HDR ${hdrs})
  file(RELATIVE_PATH REL_FIL ${PROJECT_SOURCE_DIR} ${HDR})
  get_filename_component(INSTALL_DIR ${REL_FIL} DIRECTORY)

  install(
    FILES
      ${HDR}
    DESTINATION
      include/${INSTALL_DIR}
  )
endforeach()

# 安装产生的头文件
file(GLOB_RECURSE hdrs "*.h.in")

foreach(HDR ${hdrs})
  file(RELATIVE_PATH REL_FIL ${PROJECT_SOURCE_DIR} ${HDR})
  get_filename_component(DIR ${REL_FIL} DIRECTORY)
  get_filename_component(FIL_WE ${REL_FIL} NAME_WE)
  install(
    FILES
      ${PROJECT_BINARY_DIR}/${DIR}/${FILE_WE}
    DESTINATION
      include/${DIR}
  )
endforeach()

#安装find_package所需的配置文件

set(MYLIB_CMAKE_DIR share/mylib/cmake) #note 1
include(CMakePackageConfigHelpers)
configure_package_config_file(
  mylib-config.cmake.in　#用于转变成.cmake文件的输入文件
  ${PROJECT_BINARY_DIR}/cmake/mylib/mylib-config.cmake #find_package　找到的文件
  PATH_VARS MYLIB_CMAKE_DIR #此处与　note 1　变量名一致
  INSTALL_DESTINATION ${CMAKE_INSTALL_PREFIX}/share/mylib
)

install(
  EXPORT mylibExport　#待输出安装配置文件　note 2
  DESTINATION share/mylib/cmake/
  FILE MYLIBTargets.cmake　#待输出安装配置文件名　note 3
)

install(
  FILES ${PROJECT_BINARY_DIR}/cmake/mylib/mylib-config.cmake#find_package　找到的文件
  DESTINATION share/mylib/
)

mylib-config.cmake.in

@PACKAGE_INIT@
#MYLIB_CMAKE_DIR　以及　PACKAGE_MYLIB_CMAKE_DIR中的MYLIB_CMAKE_DIR部分均与note 1的变量名一致
set_and_check(MYLIB_CMAKE_DIR "@PACKAGE_MYLIB_CMAKE_DIR@")

include("${MYLIB_CMAKE_DIR}/MYLIBTargets.cmake")#待输出安装配置文件名　note 3

list(APPEND mylib_INCLUDE_DIRS ${PACKAGE_PREFIX_DIR}/include/mylib/ )#配置头文件目录

list(APPEND mylib_LIBRARIES ${PACKAGE_PREFIX_DIR}/lib/libmylib.so)#配置库文件目录

mylib下的源文件

mylib.h

#ifndef MYLIB_H
#define MYLIB_H
#include 

void hello();
#endif//MYLIB_H

mylib.cpp

#include "mylib.h"
void hello()
{
	std::cout<<"hello world!"<<std::endl;
}

上述文件编写完成后可以用以下命令来编译安装

catkin_make_isolated --install　&& source devel_isolated/setup.sh　#ros 的安装方式，自动安装到install_isolated所在目录下
或
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=./install && make install　#cmake 的安装方式，可以安装到指定目录下

２、测试程序

以下为测试程序包目录树

test

├── CMakeLists.txt
├── launch
│ └── test.launch
├── package.xml
└── src
└── testnode.cpp

package.xml

<package  format="2">
  <name>testname>
  <version>0.0.0version>

CMakeLists.txt

cmake_minimum_required(VERSION 2.8.3)
project(test)

set(PACKAGE_DEPENDENCIES
  roscpp
  roslib
)

find_package(catkin REQUIRED COMPONENTS ${PACKAGE_DEPENDENCIES})

find_package(mylib REQUIRED) #找到自建库安装包

#安装所需文件夹
install(DIRECTORY launch DESTINATION share/test/)

catkin_package(
  CATKIN_DEPENDS ${PACKAGE_DEPENDENCIES}

  INCLUDE_DIRS
)
#mylib_INCLUDE_DIRS　为mylib　mylib-config.cmake.in文件内设置好的头文件目录
include_directories(SYSTEM  ${catkin_INCLUDE_DIRS} ${mylib_INCLUDE_DIRS})


add_executable(testnode src/testnode.cpp )# 编译可执行文件
#mylib_LIBRARIES　为mylib　mylib-config.cmake.in文件内设置好的库文件
target_link_libraries(testnode PUBLIC ${catkin_LIBRARIES}  ${mylib_LIBRARIES}  )

set(TARGET_COMPILE_FLAGS "${TARGET_COMPILE_FLAGS} -std=c++11")
set_target_properties(testnode PROPERTIES
  COMPILE_FLAGS ${TARGET_COMPILE_FLAGS})

#安装可执行文件等
install(TARGETS testnode
  ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

install(
  TARGETS testnode
  EXPORT testnodeExport
  ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  RUNTIME DESTINATION ${CATKIN_GLOBAL_BIN_DESTINATION}
)

src/testnode.cpp

#include 

#include 

int main(int argc, char** argv)
{
  ros::init(argc, argv, "testnode");
  ros::NodeHandle nh;

  hello();
  ros::spin();

  return 0;
}

launch/test.launch

<launch>
    
  <node pkg="test" type="testnode" name="testnode" args="" output="screen">
  node>
    
launch>

上述文件编写完成后可以用以下命令来编译，运行

catkin_make_isolated --install　&& source devel_isolated/setup.sh　#ros 的安装方式，自动安装到install_isolated所在目录下
roslaunch test test.launch
