## Switchroot
If you are running switchroot Linux on your Nintendo Switch, you can install
xemu from the PPA as described in in the [Download](download.md) page. However,
when running xemu you may see the following error:
```
dbus[12047]: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed in file ../../../dbus/dbus-message.c line 1362.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace
```
To fix this you can build and install SDL from source:
```bash
sudo apt install cmake build-essential
git clone https://github.com/libsdl-org/SDL && cd SDL
mkdir build && cd build
cmake ..
make -j4
sudo make install
```
Then launch xemu `LD_LIBRARY_PATH=/usr/local/lib xemu`
