## Usage
|
|
|
|
First edit your `alire.toml` file and add the following elements:
|
|
- Add `light_rp2040` in the dependency list:
|
|
```toml
|
|
[[depends-on]]
|
|
light_rp2040 = "*"
|
|
```
|
|
|
|
Then edit your project file to add the following elements:
|
|
- "with" the run-time project files. With this, gprbuild will compile the run-time before your application
|
|
```ada
|
|
with "runtime_build.gpr";
|
|
```
|
|
- Specify the `Target` and `Runtime` attributes:
|
|
```ada
|
|
for Target use runtime_build'Target;
|
|
for Runtime ("Ada") use runtime_build'Runtime ("Ada");
|
|
```
|
|
- specify the `Linker` switches:
|
|
```ada
|
|
package Linker is
|
|
for Switches ("Ada") use Runtime_Build.Linker_Switches & ("-Wl,--gc-sections");
|
|
end Linker;
|
|
```
|
|
Note that `--gc-switches` is recommended as it reduces flash and RAM usage
|
|
by removing unused code and data, but it is not mandatory.
|
|
|
|
See the project website for details on configuring the runtime.
