Subject: [musl] friendly errors for ABI mismatch
Date: Mon, 27 Jul 2020 09:27:28 -0600	[thread overview]
Message-ID: <1667998.jfqktxE8f0@localhost> (raw)

Hello,

On 32-bit systems, musl 1.2 has a new ABI (due to time64).  This results in 
programs built against musl 1.2 failing to run against musl 1.1.  That part is 
fine, but you get an error message about being unable to relocate symbols, 
which is not really insightful if you don't know about the ABI break.

glibc, on the other hand, has a minimum version specified in every binary, and 
prints an error message saying the glibc is too old if this situation is 
encountered.

I think we should add this feature to musl, so that in the future if we have 
another ABI break, users will be given useful advice about how to fix it.  Due 
to the relocation error message, a few Alpine contributors have been tripped 
up while trying to debug their work...

Ariadne
