# Exporter for the MightyOhm Geiger Counter [](https://ci.onders.org/finga/mightyohm-gc-exporter)
|
||||
A Prometheus exporter for the [MightyOhm Geiger Counter](https://mightyohm.com/blog/products/geiger-counter/).
|
||||
|
||||
## Build
|
||||
### Same architecture as system
|
||||
To compile it for the same architecture as the build system:
|
||||
```sh
|
||||
cargo build --release
|
||||
```
|
||||
|
||||
### Cross-compile for aarch64 (recent RaspberryPi)
|
||||
To cross-compile it for RaspberryPi:
|
||||
```sh
|
||||
PKG_CONFIG_SYSROOT_DIR=/usr/aarch64-linux-gnu cargo build --target aarch64-unknown-linux-gnu --release
|
||||
