前言

最近想要做有轨迹引导的多机器人编队，打算采用分布式的编队架构，实时的给每个机器人规划出目标位置，然后通过Fast_Planner生成避障路径，再通过改进的mpc进行跟踪。先记录下配置Fast_Planner时遇到的问题。

一、Could not find package …

如果出现这样的报错：
(1)通过：sudo apt-get install ros-melodic-提示缺少的包的名字进行安装。
(2)如果上面的方法不管用，需要根据提示解决：
例如：CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by “NLopt”
with any of the following names:

NLoptConfig.cmake
nlopt-config.cmake

通过与github Fast_Planner原功能包进行对比，发现在（fast_planner/baspline_opt/CMakeList.txt）目录下
我的：/CMakeList.txt

cmake_minimum_required(VERSION 2.8.3)
project(bspline_opt)
find_package(NLopt REQUIRED)
set(NLopt_INCLUDE_DIRS ${NLOPT_INCLUDE_DIR})find_package(Eigen3 REQUIRED)
find_package(PCL 1.7 REQUIRED)find_package(catkin REQUIRED COMPONENTSroscpprospystd_msgsvisualization_msgscv_bridgeplan_env
)catkin_package(INCLUDE_DIRS includeLIBRARIES bspline_optCATKIN_DEPENDS plan_env
#  DEPENDS system_lib
)include_directories( SYSTEM include ${catkin_INCLUDE_DIRS}${Eigen3_INCLUDE_DIRS} ${PCL_INCLUDE_DIRS}${NLOPT_INCLUDE_DIR}
)set(CMAKE_CXX_FLAGS "-std=c++14 ${CMAKE_CXX_FLAGS} -O3 -Wall")add_library( bspline_opt src/bspline_optimizer.cpp )
target_link_libraries( bspline_opt${catkin_LIBRARIES} ${NLOPT_LIBRARIES})

github Fast_Planner /CMakeList.txt

cmake_minimum_required(VERSION 2.8.3)
project(bspline_opt)find_package(Eigen3 REQUIRED)
find_package(PCL 1.7 REQUIRED)find_package(catkin REQUIRED COMPONENTSroscpprospystd_msgsvisualization_msgscv_bridgenloptplan_env
)catkin_package(INCLUDE_DIRS includeLIBRARIES bspline_optCATKIN_DEPENDS plan_env
#  DEPENDS system_lib
)include_directories( SYSTEM include ${catkin_INCLUDE_DIRS}${Eigen3_INCLUDE_DIRS} ${PCL_INCLUDE_DIRS}
)set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS} -O3 -Wall")add_library( bspline_opt src/bspline_optimizer.cpp )
target_link_libraries( bspline_opt${catkin_LIBRARIES} )

即去掉find_package(NLopt REQUIRED)在后面find_package中加上nlopt。其他的根据提示缺什么包装什么即可，如果遇到有的包找不到就去原仓库中找一找。

二、使用error: no match for ‘operator=’…

如果出现这样的报错：

error: no match for ‘operator=’ (operand types are ‘Eigen::internal::enable_if<true, Eigen::IndexedView<Eigen::Matrix<double, -1, -1>, double, double> >::type {aka Eigen::IndexedView<Eigen::Matrix<double, -1, -1>, double, double>}’ and ‘double’)
i * (i - 1) * (i - 2) * j * (j - 1) * (j - 2) * pow(ts, i + j - 5) / (i + j - 5);

根据提示找到：fast_planner/poly_traj/include/poly_traj/polynomial_traj.h
根据提示的行数将for循环的圆括号里的double改为int，注意是两个！
