MerlinWRT - compile instructions?

[RMerlin]

How can we build for aarch64?

You cannot. All the userspace precompiled components are 32-bit.

You cannot. All the userspace precompiled components are 32-bit.

Thank you. Is the smaller size of the 32 bit binaries the only reason ASUS has chosen to use this mix (64 bit for the kernel and 32 bit for the programs)?

I don't know. I suspect memory usage might have been a factor. Broadcom might have had other technical reasons to stick to 32-bit userspace with their SDK. Switching 15+ years old code to a new 64-bit architecture would be a major undertaking requiring extensive QA - something Broadcom might have felt wasn't worth the effort.

Thank you.

Hi all.

Apologies to resurrect an old thread, but having issues building from source (master). Tried in both WSL2 and a standalone VM. Ubuntu 20.04. Rolled back to automake-1.15, as well.

AC68U (NG source):
Fails on:
release/src-rt-6.x.4708/router/aaews/prebuild/RT-AC68U/aae_ipc.o': No such file or directory
make[5]: *** [Makefile:516: aae_ipc.o] Error 1

Any ideas?

Thank you.

Thank you.

RT-AC68U cannot be built from master, only from 386_x.

Any ideas?

You should be able to get a good AC68U build using the amcfwm script on a fresh Ubuntu 20.04 VM.

Thank you. Went back to automake-1.16 and needed libltdl-dev. Looks good.

I tried to compile a firmware version with debug info,but i keep encounter this :
