Re: [Pharo-users] Pharo for Raspberry Pi

As I remember, last time I used the standard squeak vm that is shipped with the rpi3, and it worked fine with Pharo. I don't remember whether it was a spur image or not, but it worth trying out. -- View this message in context: http://forum.world.st/Pharo-for-Raspberry-Pi-tp4945740p4946015.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Smalltalkers will, eventually, win. So says this old C++ programmer.

Re: [Pharo-users] Pharo Audio?

by J.F. Rick

Yes, sound support on Linux is not great and probably won't be good until 64-bit. If you are just looking to play an MP3 based on some user action, you could just try using a command-line MP3 player and then using an OSProcess to launch it, stop it, etc. It's a bit ugly code but might need your needs.
