@yuanren
这是另一个，但devel里面已有内容，却无法执行

@yuanren ROS的工作空间环境变量是不是没有设置。有没有souce工作空间的setup.bash

[Yuanren]

@weijiz 你好，我source了，还是出现这个情况。

@weijiz 这是我的CMakelist，麻烦你帮我看一下。不知道是不是我Ubuntu系统的问题，昨天运行还可以。

cmake_minimum_required(VERSION 3.0.2)
project(sim)

Compile as C++11, supported in ROS Kinetic and newer

add_compile_options(-std=c++11)

Find catkin macros and libraries

if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)

is used, also find other catkin packages

find_package(catkin REQUIRED COMPONENTS
roscpp
rospy
std_msgs
)

catkin_package(

INCLUDE_DIRS include

LIBRARIES sim

CATKIN_DEPENDS roscpp rospy std_msgs

DEPENDS system_lib

)

Specify additional locations of header files

Your package locations should be listed before other locations

include_directories(

include

${catkin_INCLUDE_DIRS}
)

catkin_package()

add_executable(bat_pub
src/bat_pub.cpp
)
target_link_libraries(bat_pub
${catkin_LIBRARIES}
)

add_executable(tst
src/tst.cpp
)
target_link_libraries(tst
${catkin_LIBRARIES}
)

@yuanren 你的工作空间太乱了，可能source了错误的工作空间

[Yuanren]

@weijiz 好的
