Problems with distcc on earmv4

[John Klos <john%ziaspace.com@localhost>]

Hi,

I run distcc for pkgsrc on many architectures: VAX, m68k sparc, sparc64, 
SuperH, mipsel, mips64eb, earm (v5), aarch64eb. I've only ever had a 
problem trying to run it on Alpha, but that appeared to be a distcc 
problem, not anything related to pkgsrc.

For some reason I'm seeing issues with earmv4 specifically. I'm using the 
exact same setup as other machines (just changing the port number for 
the corresponding distcc for earmv4), on a new system with no local 
changes.

Here, as an example, I'm trying to build benchmark/flops. This doesn't 
even use distcc because it compiles and links at the same time (which 
distcc doesn't handle), so there's no reson this shouldn't work:

Where is "gcc: error: c: No such file or directory" coming from? 
Any ideas, or any thoughts about what to check? Why would earmv4 be any 
different?

This is a system running NetBSD 10.0_BETA from 4-March-2023 sources. I 
didn't get details then, but when I tried getting distcc working on the 
NetBSD-9 earmv4 system I'm using to build pkgsrc binary packages, it 
didn't work there, either, and I'm imagining the reasoning is likely the 
same.

Thanks,
John
