Editing WSL (section)

=== Ubuntu in WSL===
3) Updating Your Ubuntu System
Now that you can access internet, you can update your Ubuntu.

Follow "Update and upgrade packages" in Set up a WSL development environment | Microsoft Docs. 



4) Setup VS Code and everything else
Now it's time to setup your VS code and terminals so that you can access your files on the VM to do this follow

Set up a WSL development environment | Microsoft Docs sections:

Set up Windows Terminal

File storage

Use Visual Studio Code



5) Install what we need for building the desktop app
Run the following command to get your environment ready, these comments should be ran in WSL Ubuntu.

5.1) cmake
sudo apt install cmake

5.2) Clang as compiler:
sudo apt install clang-10 --install-suggests

After running this command a symbolic (type of file in Linux that points to another file or a folder) is created, when you use clang-10 and clang++-10, clang 10 C and C++ compilers are targeted respectively.

You can read more about this to understand it better by reading the answer by karel at How to set Clang 9 as the default C++ compiler on Ubuntu 19.10? - Ask Ubuntu (do not follow this as instruction but read to understand what is going on, you can check your symbolic to understand it better)

6) Update CMakeList.txt (if we did not push changes by the time you use this document)
Add the following lines to CMakeList.txt (at /firmware/Desktop) before the line containing "project(XXXXXX)", this would set the compilers for project, if you set them after this line it will not work correctly.

set(CMAKE_C_COMPILER "clang-10")
set(CMAKE_CXX_COMPILER "clang++-10")

7) Build the Project (to be updated)
cd firmware/Breathing

rm -rf build

cmake -B build .

cd build

make

7.1) Troubleshooting
7.1.1) If CMake Does Not Apply Your Changes

rm -f CMakeCache.txt

Then redo build 

8) Run the Tests
cd /OS-firmware/

source run_small_window.sh

You may need to change the access to the run_small_window.sh by "sudo chmod 777 run_small_window.sh" (on WSL this is not needed)
