## <a id="sysroot"></a> Getting system root for Linux cross-compilation
Cross-compiling any program for an embedded Linux board generally required parts of the target root
file system on the development/host computer. For the Q7S, you can install the cross-compilation
root file system by simply installing the SDK. You can find the most recent SDK
[here](https://eive-cloud.irs.uni-stuttgart.de/index.php/apps/files/?dir=/EIVE_IRS/Software/xiphos-q7s-sdk).
If you are compiling for the Q7S or the TE7020, the `ZYNQ_7020_SYSROOT` environment variable
must be set to the location of the SDK compile sysroot. Here is an example on how to do this
in Ubuntu, assuming the SDK was installed in the default location
```sh
export ZYNQ_7020_SYSROOT="/opt/xiphos/sdk/ark/sysroots/cortexa9hf-neon-xiphos-linux-gnueabi"
```
If you are comiling for the Raspberry Pi, you have to set the `LINUX_ROOTFS` environmental
variable instead. You can find a base root filesystem for the Raspberry Pi
[here](https://eive-cloud.irs.uni-stuttgart.de/index.php/apps/files/?dir=/EIVE_IRS/Software/rootfs).

## <a id="q7s-sysroot"></a> Getting the Q7S system root
It is necessary to copy the Q7S system root to your local development machine for libraries
like `libgpio`. You can find the system root for the Q7S, the Raspberry Pi and the
Beagle Bone Black for download here
[here](https://eive-cloud.irs.uni-stuttgart.de/index.php/apps/files/?dir=/EIVE_IRS/Software/rootfs&fileid=831849).
Download it and unzip it somewhere in the Xilinx installation folder.
