DS918+ DSM7.1 Compiling issue

[lowrisk75]

Description
I cant successfully compile on a DS918+ running DSM7.1
It's seems that I have some DNS issue as there is a lot of Temporary failure resolving

when I manually ping the same host it's seems to be fine though

sudo ping archive.ubuntu.com

running the docker run command also give me some issues

Any luck on this @lowrisk75 ? I've been trying to compile for my DS918+ since earlier this year and given up a few times. Curious if anything has changed and anyone got this working.

I suggest to compile the package in a different environment. Running the process on your NAS may suffer from some specific limitation in the configuration of the Linux platform. The compilation process do not require the same environment as the target platform: it is possible to compile for Armada platform using an Intel PC.
For instance, I'm compiling on a MacBook M1 (after installing Docker Desktop) and it works well. I think the result could be the same on Windows or Linux.

Works well for DS918+ (apollolake) on both DSM 7.1 and DSM 7.2 when compiling on macOS Ventura (Apple Silicon).
