pcl 1.7.2 make errors

Posted 2021-03-20 williamc17

A dependency was removed accidentally

Several weeks ago, a dependency was removed by apt remove libc6. After I reinstalled ROS, everything seems to work well.

But when compiling PCL, some share lib may be removed with the previous dependency.

So error occured:

Problem solved

Since just some lib missing, it is easy to solve the problem by download the file to where they belong to.

In my machine missing files

~$ locate libpcap

Focus on the lib, which means we need is some file has .a or .so.

/usr/lib/x86_64-linux-gnu/libpcap.a
/usr/lib/x86_64-linux-gnu/libpcap.so

Download the libpacp.a and libpcap.so. Copy them to the directory

sudo cp ~/Downloads/libpcap.a /usr/lib/x86_64-linux-gnu/
sudo cp ~/Downloads/libpcap.so /usr/lib/x86_64-linux-gnu/
