Hi,

I just tried to install your gem on an Raspberry Pi 2 Model B Rev 1.1 - but got this error message:

root@loxberry:/opt/loxberry# gem install balboa_worldwide_app
Building native extensions. This could take a while...
ERROR:  Error installing balboa_worldwide_app:

Do you have any advice what to do? It's a Raspbian distribution: PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Thanks for your help!

I investigated a bit more and installed "rake" separately - then I get this error message:

I found the solution on my own :-) To be able to build the gem native extensions an additional package "ruby-dev" has to be installed:

sudo apt-get install ruby-dev.

With this installed, the installation of balboa_worldwide_app worked fine.

Thanks

This is great to know! I too have had a terrible time trying to get this to work on a Pi. I will have to try this myself. Thanks @JochenKoehler69
