[M3devel] building CM3 on a Raspberry Pi?

[Jay K]

 > Fatal Error: unrecognized backend mode: C


Make sure you ./update.py your main toolset first.
Also, while the C backend was working a year ago, for quite
a while I did not change the builder to know about it directly.
I was going via m3cgcat.
So you need to be fairly current, or else modify the
config files a different way, and have it be slower.
