Hi,

BoUML for architecture armhf, to use with raspberry pi debian?

I currently have bouml 4.22.2 compiled for it.

Hello,

I never used raspberry pi

Which raspberry pi do you have ?

Which debian release do you use on ?

Regards,
Bruno

Hi,

I use a Raspberry Pi 2, currently Raspbian is Debian Stretch based. I had BoUML 4.22 compiled directly on the raspberry, I didn't cross compile it. When I try to install it from bouml repository it says it doesn't support "armhf" architecture.

Regards,
Federico.

Ok, I ordered one to produce the Raspbian deb

Yes I do not yet manage that case

Bouml 7.1.2 is available for Debian Stretch under armhf, this means for Raspberry Pi 2

P.S. Because I forgot to command a fan and a radiator I compiled Bouml without parallelism ("-j 1") to limit CPU temperature, because of that the build taken more than 6 hours to be made :shock: :?

Haha, yes they take some time, I only use a radiator, for bouml 4.22 I used -j3, and wrap it around on a .deb

Not many end user software is prepared to be fast by design, and bouml runs great on this low power, low memory, low cpu, low cost boards.

A radiator in pure copper is surprisingly very efficient and allows to compile in "-j 4" with the CPU at 62° (centigrade) while the ambient temperature is 20°

Adding the fan the temperature is 15° less

So I am ready to compile a new version of Bouml as fast as possible in any condition :D

:lol:

From 900 Mhz to 1050 Mhz is not a big change, I don't use the GPU whose speed can be doubled (Overclocking and Stability Testing the Raspberry Pi 2)
