Re: A beginner's question

Hi Michael,

yes, you're right, a pre-compiled package is simpler to use!

I first started with the instructions I found here:

https://www.nongnu.org/gm2/12/development.html

Compilation with bootstrapping the default and m2 finally went fine
but with the resulting gm2 I could not compile any MODULA program
beyond hello.mod.

I then switched to Debian with a pre-compiled package. I now use
Debian sid which I think is the same as unstable. A gm2 --version shows:

gm2 (Debian 12.2.0-14) 12.2.0

With this gm2 everything is working fine except the few 'findings' I'm
trying to report.

Compiling C programs is also working fine, both on my Debian sid and
on my Arch Linux (wich is running 'on the bare metal'). Debian sid is
in a VMware box.
