产生问题:没有规则可以建立目标/usr/lib/x86_64-linux-gnu/libpcl_common.so


8

我正在按照本教程来运行PCL(点云库)提供的示例之一:https : //www.youtube.com/watch?v=CXK95Hi4M7I

但是当执行make命令(https://youtu.be/CXK95Hi4M7I?t=243)时,我得到以下输出:

yalishanda@yalishanda-thinkpad-x200:~/PCL/visualRangeExample/build$ make
make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libpcl_common.so', needed by 'range_image_visualization'.  Stop.
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/range_image_visualization.dir/all' failed
make[1]: *** [CMakeFiles/range_image_visualization.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

有人可以告诉我问题是什么以及如何解决?

谢谢

你已经libproj-dev安装好了吗?安装它,然后重试。

@Seth是的,它已经被安装。我用Makefile更新了我的帖子

错误:

make [2]:***没有规则来创建目标'/usr/lib/x86_64-linux-gnu/libpcl_common.so',这是'range_image_visualization'所需要的。停止。

表示make无法找到/usr/lib/x86_64-linux-gnu/libpcl_common.so完成编译所需的文件。

首先检查文件是否存在:

$ stat /usr/lib/x86_64-linux-gnu/libpcl_common.so  
stat: cannot stat '/usr/lib/x86_64-linux-gnu/libpcl_common.so': No such file or directory  

好的,所以我们需要安装它。找出软件包提供什么的最简单方法libpcl_common.so是使用名为的工具apt-file。安装并设置:

sudo apt-get install apt-file
apt-file update

完成后,您可以运行:

$ apt-file search /usr/lib/x86_64-linux-gnu/libpcl_common.so  
libpcl-common1.8: /usr/lib/x86_64-linux-gnu/libpcl_common.so.1.8
libpcl-common1.8: /usr/lib/x86_64-linux-gnu/libpcl_common.so.1.8.0
libpcl-dev: /usr/lib/x86_64-linux-gnu/libpcl_common.so

然后你走了!安装后libpcl-dev,您应该会很高兴。

还值得注意的是,通常,在源目录中,应该有一个README文件,其中列出了需要安装的依赖项,这将有助于消除这种猜测并节省一些时间。


顺便说一句,通常我会使用apt-cache寻找软件包。换句话说,我在这里尝试了“ sudo apt-cache pkgnames libpcl”,它给出了更多的选择。但是我根本不知道要安装哪一个。总是使用您的替代文件(即apt-file)更好吗?它们有何不同?

@trilolil apt-cache search仅搜索软件包名称和简短描述。apt-file search正在查看软件包内部,以查看其中一个包含您要搜索的文件。
