## cutearm
To compile Qt for Raspberry, there are generally two ways:
1. compile on device
2. use cross-compilation
First solution might be slow: have you ever tried to compile Qt on Raspberry 1? It takes more than 24 hours and you're not really satisfied when compilation breaks 1 hour after you started it while you're in your bed dreaming to get those `.so` files.
Second solution works well but is not easy to setup and maintained.
Here is a third solution which takes advantage of docker ARM images in order to work directly on Raspbian like on your Raspberry but within a container.
## Overall steps
* Create a Raspbian docker image
* Build a container based on this image with Qt compilation deps
* SSH on this container and perform compilation steps of Qt
## Steps
* `./build-raspbian-docker-image`: create a raspbian docker image
* `./build-raspbian-docker-container`: create the container able to compile Qt
* `./start-raspbian-docker-container`: start the container with volumes mounted
User is `worker`, password too.
* `docker inspect` to get the container IP
* `ssh worker@ip`
* Then:

```
This takes around 10h to compile Qt on an average machine.
## Test
```bash
mkdir qt-sample-app-build
cd qt-sample-app-build
../Qt5.12.0/bin/qmake -recursive ../qt-sample-app/qt-sample-app.pro
make
./qt-sample-app
```
