Go golang on MIPS CPU

[ROuNIN]

Hello,
How are the efforts for porting golang onto MIPS progressing? Will
this ever happen?

I was wanting to run golang code on a MIPS CPU powered WD My Book Live
as it is a
low power NAS which can be configured by modifying the Debian running
on it.

I don't know about efforts to port the gc compiler to MIPS, but gccgo
does work on MIPS GNU/Linux targets.

Found out that the WD My Book Live is not a MIPS CPU but a PowerPC

rounin@MyBookLive:~$ more /proc/cpuinfo

The bogomips rating of 1600.00 seems higher than what I have seen for
ARM CPUs?

How are the efforts for porting golang onto PowerPC progressing? Will
this ever happen?

The gccgo compiler already supports PowerPC.

To use gccgo for MIPS you need to build GCC 4.7.1 as a cross-compiler
for a MIPS target. Saying more than that involves many details about
what exactly you want to do. My general notes on the topic are at
http://www.airs.com/blog/archives/492 . For specific questions about
building GCC as a cross-compiler I would recommend the mailing list
gcc-...@gcc.gnu.org. Note that you will not get a useful answer to a
general question like "how do I build a MIPS cross-compiler" but you
may get one for a specific question about a specific problem that you
encountered while trying to build.
