Working Guix on 64 bit PowerPC.

Working Guix on 64 bit PowerPC.

[Tobias Platen]

Hello,

I've got the wip-ppc branch of Guix compiling unmodified on my Talos II.
Since the POWER9 is backwards compatible with the PowerPC G4, it can run
the existing bootstrap binaries for powerpc-linux. The binaries from
http://flashner.co.il/guix/bootstrap/powerpc-linux/ have been verified
working on my Talos II. I also plan to setup a mirror of those binaries.

[user@staticvoid guix]$ arch
ppc64
[user@staticvoid guix]$ ps -A | grep guix
 1104 pts/1    00:00:00 guix-daemon
[user@staticvoid guix]$ ./pre-inst-env guix build hello
guix build: error: could not find bootstrap binary 'tar' for system 'powerpc64-linux'
[user@staticvoid guix]$ cat /proc/cpuinfo 
processor	: 0
cpu		: POWER9, altivec supported
clock		: 2154.000000MHz
revision	: 2.2 (pvr 004e 1202)

I found that once I rebased on core-updates it stopped building as
nicely. I don't remember where the failure was, but it was somewhere in
commencement.scm.

I am really glad to hear that it worked :)

To address that, you can hack ‘bootstrap-executable’ in
gnu/packages/bootstrap.scm so that it uses “powerpc-linux” when it’s on
“powerpc64-linux” (similar to what’s done for x86_64-linux).

HTH!

In the mean time you could use './pre-inst-env guix build
--system=powerpc-linux hello'. I'm especially interested if you can
build guile-final since I get some Segfault while compiling
ice-9/boot-9.go.

./pre-inst-env guix build --system=powerpc-linux -e '(@@ (gnu packages
commencement) guile-final)'
