1 First, basic definitions.
3 distcc ==> compile on machine A for machine B. No mention of whether
4 the processors are different architectures.
6 cross-compile ==> compile under architecture A for architecture B
8 I'm trying to run a distccserver in a 32-bit VM on a 64-bit host, for
9 the benefit of my ancient 32-bit-only netbook. Yeah, "it'll work" using
10 the native 64-bit host OS. But any stuff that links against 32-bit
11 libraries is going to be sent back to the netbook to compile locally.
12 That defeats the whole purpose of distcc. This is why I want the 32-bit
13 VM to compile for the 32-bit Atom. Here's the launch script for the
14 32-bit VM on the i3 machine...
16 #!/bin/bash
17 qemu-system-i386 -enable-kvm \
18 -cpu host -display gtk \
19 -drive file=gentoo32.img,format=raw \
20 -drive file=linuxswap.img,format=raw \
21 -net nic,model=virtio \
22 -rtc base=localtime,clock=host \
23 -net user,hostname=gentoovm,hostfwd=tcp::2022-:22,hostfwd=tcp::3632-:3632,hostfwd=udp::3632-:3632 \
24 -m 3G -name "Gentoo VM" \
25 -parallel none \
26 ${@}
28 Amongst other things, it forwards port 3632 destined for the host, to
29 the VM. "ssh -p 2022 root@" works from the Atom to the
30 VM. I get an ssh teminal. There's no iptables blocking things, and
31 distccd is running on the VM (it's in the default rc-update level). Yet
32 the Atom spits out stuff like...
34 distcc[8248] (dcc_pump_sendfile) ERROR: sendfile failed: Broken pipe
35 distcc[8248] (dcc_writex) ERROR: failed to write: Broken pipe
36 distcc[8248] Warning: failed to distribute shell.c to,lzo,cpp, running locally instead
38 ...when trying to outsource the compile. What am I doing wrong?
