Build Error! /usr/bin/ld: /lib/x86_64-linux-gnu/libcaca.so.0: undefined reference to mousemask@NCURSESW6_5.1.20000708'

[Summer2474]

ORB-SLAM3 works well in my computer, however, when I try to build ORB-SLAM2, I get some strange errors that I fail to solve! If someone encounters a mistake similar to mine, please tell me how to fix it, and I don't find any effective solution now.

Hello, did you solve this issue, I got the same problem. Any help would be appreciated.

[pramitd]

Same problem. Do you have the solution. Kindly give a reply, thanks.

[musalmaz]

I don't understand which way solved my problem but it possible solutions are: 1 - if you use conda, run your command without a conda environment, even base., 2 - the reason for the problem may is opencv, resolve this.
