Hi Axel
Seems to work well but not tested exhaustively across different code and

Did exactly these steps and got this far at 4:30am this morning! :o}

This is where I got badly stuck, though I might have the answer - see below=
.
=20
I first tried about 10 RPMs from various places that are meant to be for
Redhat 8 on i386 (or i586 or i686 - I am guessing it shouldn=B9t matter?) and
whenever I try to install them with the recommended command, e.g. :
rpm -i --ignoreos --root /compat/linux --dbpath /var/lib/rpm
/mnt/Desktop/apt-0.5.5cnc6-fr0.rh80.1.i386.rpm
I get this message:
"package apt-0.5.5cnc6-fr0.rh80.1 is for a different architecture"
I then thought that the recently-installed linux rpm might be the right way
to deal with this, so:
/compat/linux/bin/rpm -i --ignoreos --root /compat/linux --dbpath
/var/lib/rpm /mnt/Desktop/apt-0.5.5cnc6-fr0.rh80.1.i386.rpm

Even though all of these executables and libraries are installed as standar=
d
in linux_base-8.
Then another thought; use '--ignorearch' with the FreeBSD rpm command. This
seems to install linux apt as required! :o) Maybe this is the right way t=
o
go? I will investigate further and let you know.

Will try these later today.

So I can't get to these steps until I have worked out how to install the GC=
C
tools for linux. As far as I can tell I have the following options:
1) Work out how to make RPMs work as discussed above. Would like this
anyway to be able to use more linux stuff.
2) Install linux_devtools from ports - but:
/usr/ports/devel/linux_devtools % make
=3D=3D=3D> linux_devtools-8.0_3 is only for i386, and you are running amd64.
3) Find a tarball of the GCC toolset for RH8 i*86 and extract it into
/compat/linux
4) ? Any others ?

I will just be happy to have 32-bit working for now!
Thanks for the input
