Aw: Re: building x86-32

ok thanks
but I still have a Linker-Error:

ld: i386:x86-64 architecture of input file `/usr/lib/gcc/x86_64-linux-gnu/9/crtbeginS.o' is incompatible with i386 output
ld: i386:x86-64 architecture of input file `/usr/lib/gcc/x86_64-linux-gnu/9/crtendS.o' is incompatible with i386 output

I did 'apt-get install lib32gcc-10-dev' previously.
So maybe a -m32 flag missing somewhere?

Greets,
B.

This is correct. The output you mentioned here is from building some host
tools that are needed by the L4Re build system.

Best,
Matthias.
