# Kotlin MPP: Unable to compile C bridges

How to fix `e: Unable to compile C bridges` with Kotlin Multiplatform on Linux.

We’ve come across this problem several times, and for the first time, it was a bit problem to find what’s wrong.

Basically, it’s missing libncurses5 which you can simply install on Ubuntu/Debian:

```shell
apt-get install libncurses5
```

This problem usually hits us on CI/CD, when in a clean environment. The last time, it was with Github Actions after moving our runner to a new set of servers.

This one is just a quick tip that can save you nerves eventually 😃.
