# AppImage crashes


If the linux AppImage binary crashes upon startup, make sure your `LD_LIBRARY_PATH` environment variable is empty. [#579](https://github.com/radareorg/cutter/issues/579)

# Compilation error
> r_core development package not found

If you installed radare2 and still encounter this error, could be your `PATH` environment variable is set improperly (doesn't contain `/usr/local/bin`). That can be, for example, due to `Qt Creator.app` being copied over to `/Applications`.
To fix this, append `:/usr/local/bin` to the `PATH` variable within the *Build Environment* section in Qt Creator. See the screenshot below should you encounter any problems.

On OS X you can also try:

- `PKG_CONFIG_PATH=$HOME/bin/prefix/radare2/lib/pkgconfig qmake`
- `PKG_CONFIG_PATH=$HOME/cutter/radare2/pkgcfg qmake` (for modern version and if radare2 was installed like the submodule)

Or radare2 libs could be installed to `/usr/lib/pkgconfig/`, so you can add variable `PKG_CONFIG_PATH` with value `/usr/lib/pkgconfig/`

> OS X libjpeg error

On Mac, QT5 apps fail to build on QtCreator if you have the libjpeg lib installed with brew. Run this command to workaround the issue:
```
sudo mv /usr/local/lib/libjpeg.dylib /usr/local/lib/libjpeg.dylib.not-found
```

# Keyboard layout issue
Some people report that they have keyboard issues. Usually it is because the Xorg layout is wrong. You can check it with:
```setxkbmap -query``` Most of the time using ```setxkbmap us``` solves the issue, but it might not be enough and require some more advanced Xorg configuration.
