今天安装PCL-1.8和VTK-7.1.1后,运行测试代码已经出现画面了,说明pcl是好的,
但是编译LVI-SAM和LIO-SAM代码还是报错:
CMake Error at /opt/ros/melodic/share/pcl_conversions/cmake/pcl_conversionsConfig.cmake:113 (message): Project ‘pcl_conversions’ specifies ‘/usr/include/pcl-1.8’ as an include dir, which is not found. It does neither exist as an absolute directory nor in ‘${
{prefix}}//usr/include/pcl-1.8’. Check the issue tracker ‘https://github.com/ros-perception/perception_pcl/issues’ and consider creating a ticket if the problem has not been reported yet.
或者是
CMake Error at /home/moro/work_ws/devel/share/pcl_ros/cmake/pcl_rosConfig.cmake:106 (message): Project ‘pcl_ros’ specifies ‘/usr/include/pcl-1.8’ as an include dir, which is no found. It does neither exist as an absolute directory nor in ‘/opt/ros/kinetic//usr/include/pcl-1.8’
解决过程
然后执行
locate pcl-1.8
返回
/usr/include/pcl-1.8
执行
cd /usr/include/pcl-1.8
却进不去那个文件夹.
然后再回看报错内容,该错误的意思是说在/usr/include/下并没有/pcl-1.8文件夹，同时/pcl-1.8文件里应该要有pcl_conversions和pcl_ros包，
所以
执行
locate pcl_conversions
locate pcl_ros
返回 可以看到这些包都在/opt/ros/melodic/share目录下
pcl_conversions/ pcl_msgs/ pcl_ros/
我们可以
cd /usr/include
然后
mkdir pcl-1.8
然后
cd /opt/ros/melodic/share/pcl_conversions
把这三个包全部复制过去:
sudo cp pcl_* /usr/include/pcl-1.8/
再编译就通过啦,这个问题搞了我好久,记录下.
如果你的电脑上没有这几个包,去对应的网站下载再复制过去也可以.
