I’m trying to following the instructions found here: cardano-node/install.md at master · input-output-hk/cardano-node · GitHub
When running cabal I get the following error:
/lib/ld-linux-aarch64.so.1: No such file or directory
Doing this on a clean ubuntu 18.04 image (in docker)
Can’t seem to figure out how to resolve this.
Well, are you using an ARM architecture ?
I’m doing this inside a Docker images on a Macbook Pro
sysctl -a | grep brand
machdep.cpu.brand_string: Intel(R) Core™ i9-9980HK CPU @ 2.40GHz
machdep.cpu.brand: 0
Sorry this probably seems obvious to someone who as experience building on various architectures, but I’m rather new to that space.
Ah, I see the problem. The binary that I’m downloading is “Binary download for Ubuntu Linux 18.04 (aarch64, requires glibc 2.12 or later)” … the “aarch64” = arm and not the architecture I’m on.
The other option “Binary download for Ubuntu Linux 16.04 (x86-64, requires glibc 2.12 or later)” seems to be the one I want 'x86-64" …
I was paying more attention to the 18.04 vs 16.04
Yes, that’s it. 
When you want to know the architecture of any machine you have access to then you can use
$ uname -m
And on Ubuntu there is also arch command from coreutils package.
