Problems building pico examples

[seamusdemora]

Apparently I have bodged something... but I don't know what it is exactly.

I did an install of the pico sdk back in February of this year. I've not "pulled" any updates since then - until today. Since the git pull(s), I cannot even build the blink example. Can someone tell me where I've "gone wrong"?

As part of the RP2350 release there have been big updates to both pico-sdk and pico-examples.

My assumption is that you missed the bit where it says "You should delete/recreate all build directories when upgrading from previous versions of the Raspberry Pi Pico SDK" ?

@lurch : In fact I did miss that completely! I guess that was a post on the GitHub site?... didn't see anything about it in my git output.

Thanks!

I guess that was a post on the GitHub site?

Yes, there's a link to it in my previous comment... :slightly_smiling_face:

[seamusdemora]

Yes - I got it, and thanks again.
