I’ve just updated my project to 2019.1.0f2 and I keep getting an error about the Burst Compiler package, even though I’m not using the burst compiler.
The errors are as follows:

and

I have tried the following to fix issue:

  • Installing Burst from package manager
  • Rebuilding Library folder

Both didn’t help. I have also opened this project on my Windows machine and the issue is no present.

Is anyone else having this issue, or any ideas on how I can fix this?
Thanks in advance for any help :slight_smile:

Reason: libtinfo.so.5: cannot open shared object file: No such file or directory

That looks to be the issue.

I was also having this issue and have fixed it by installing ncurses5-compat-libs

I was on Manjaro so could get it from the AUR: AUR (en) - ncurses5-compat-libs

If you using Ubuntu or Debian, install the libc6-dev package.

sudo apt install libc6-dev-amd64

At least it fixed it for me.

There is also a libncurses-dev package available, you may install this instead to be sure.

I had a new install and ran into this error again. Tried above options, but libncurses5 package is what seemed to have fixed it or maybe a combination of what you guys mentioned, I’m not actually sure, but its fixed now :slight_smile: Thanks for the help.

Same problem here on Mint. I’m using Unity 2020.2.7f1.

I had the same issue on MacOS and fixed it by installing ncurses using brew

brew install ncurses
