Some users will be wanting to compile pico projects from their raspberry pis, some of which are 32bit only. And even on 64bit devices 32bit Raspbian is the default install by the r-pi foundation - https://www.raspberrypi.com/software/operating-systems/.

As such it would be great to have a 32bit version of the toolchain.

I too would really appreciate a compile for 32 bit - arm7l

Can you run gcc -dumpmachine; gcc -v on your system and paste the output? It should be trivial to add, but I need to know the tuple...

This is already there in the Makefile, and the existing binary will work (but P.Io won't install until I re-upload the entire chain.)

See https://github.com/earlephilhower/pico-quick-toolchain/pull/17

It'll be in the next toolchain build, no actual compilation changes/etc. required...

HarvsG commented 1 year ago

Great that is good news. When is the next build likely to be?

maxgerhardt commented 1 year ago

@earlephilhower sorry to ping you directly, are the packages already uploaded and are just waiting for manual review by the PIO team, or has the push not happened yet? There seem to be quite a few people wanting to run this on a Pi with 32-bit OS :/

earlephilhower commented 1 year ago

Running the Arduino toolchain on a RPi 32bit (I assume only RPi3) must really be a test of patience, ouch.

@maxgerhardt it's not been rebuilt yet. Since it's a big D/L for folks I wanted to also get https://github.com/earlephilhower/pico-quick-toolchain/issues/23 and maybe https://github.com/earlephilhower/pico-quick-toolchain/issues/8 in as far as changes before the update.

Worst case I'll do a build by year's end...
