Can't compile flutter-pi

[goncalo-almeida-mc]

I am using a Raspberry Pi Model 3 B (2015).

I have installed:

• engine binaries,
• cmake, graphics, system libraries and fonts;

Updated system fonts;

During the compiling process:

• $(cmake ..) command didn't raise any errors;
• $(make -jnproc) this is where the trouble began with several errors showing up regarding DRM variables.

What should I try to do?
I have no idea what I did wrong. At first, cmake was raising a version error (3.7 when >3.10 was required) so I used snap's cmake (3.20))

Fixed some problems but still fails linking

what distro are you using? if you run raspbian, is it possible you have a really old version of it?

[goncalo-almeida-mc]

Kernel version is 4.19.57-v7+

[goncalo-almeida-mc]

Just updated to 5.10.46-v7+ (and rebooted), the problem keeps being the same

[ardera]

thx, but what distro are you using? kernel version is good to know too, but distro is really what matters here.

Maybe this helps?

you're running raspbian stretch, which is pretty old and EOL since mid 2020. You can upgrade to Raspbian buster like this: https://www.raspberrypi.org/documentation/raspbian/updating.md (See the Upgrading from Stretch to Buster section)
