permission denied problem at linking #148

Open arifle opened 6 years ago

Hi guys,

I got a problem when compiling ROS build. It seems to be a problem of generating executable files which said that there is no permission to write disk ?? Actually, I got a similar error before this and it was relatively clear to know where (which directory) I lost the permission and it was fixed via a chown -R uName Directory. I don't know how I can fix this error cause I don't know very much about Linux Makefile and hence don't know what exactly the directory is. 

$ buils_ros.sh

I solved it few minutes ago. chown -R uName ./ORB_SLAM2
