4. Run the CMake configuration to create the build system in a `Debug` folder.
Navigate into the `eive_obsw` folder first.
4. Run the CMake configuration to create the build system in a `build-Debug-Q7S` folder.
Add `-G "MinGW Makefiles` in MinGW64 on Windows.
```sh
mkdir build-Debug-Q7S && cd build-Debug-Q7S
cmake -DTGT_BSP="arm/q7s" -DCMAKE_BUILD_TYPE=Debug -DOS_FSFW=linux ..
cmake --build . -j
```
You can also use provided shell scripts to perform these commands
```sh
cd cmake/scripts/Q7S
./create_cmake_debug.sh
cd ../../..
```
This will invoke a Python script which in turn invokes CMake with the correct
arguments to configure CMake for Q7S cross-compilation.
You can build the hosted variant of the OBSW by replacing `-DOS_FSFW=linux` with
`-DOS_FSFW=host`. There are also different values for `-DTGT_BSP` to build for the Raspberry Pi
or the Beagle Bone Black: `arm/raspberrypi` and `arm/beagleboneblack`.

## Running cppcheck on the Software
Static code analysis can be useful to find bugs.
`cppcheck` can be used for this purpose. On Windows you can use MinGW64 to do this.
```sh
pacman -S mingw-w64-x86_64-cppcheck
```
On Ubuntu, install with
```sh
sudo apt-get install cppcheck
```
You can use the Eclipse integration or you can perform the scanning manually from the command line.
CMake will be used for this.
Run the CMake build generation commands specified above but supply
`-DCMAKE_EXPORT_COMPILE_COMMANDS=ON` to the build generation. Invoking the build command will
generate a `compile_commands.json` file which can be used by cppcheck.
```sh
cppcheck --project=compile_commands.json --xml 2> report.xml
```
Finally, you can convert the generated `.xml` file to HTML with the following command
```sh
cppcheck-htmlreport --file=report.xml --report-dir=cppcheck --source-dir=..
```
