Hi,
While I know it has not been explicitly discouraged, is there some reason crosstool-ng is not recommended for building a cross-compiler? The web site is:
http://crosstool-ng.github.io/

my experience has been that I have specific work flow requirements for the order in which I build the cross compilers and libraries. When I tried to integrate crosstool-ng it just became a pain trying to get my requirements met... literally was easier to just use cmake.
others will probably disagree but there you have it.

Well, the instructions in the OSDev Wiki predate crosstool-ng (v0.0.1 released Apr 10, 2007) by a comfortable margin, and are known to work.

I think it is an excellent toolchain and Ive used it to compile my os for a long time.

Not as long as I have been using the wiki instructions.
The other point is, while it would be OK to
mention crosstool-ng in the Wiki, or even write an introduction on its use,
replacing the existing instructions with those for a third-party tool would be suboptimal IMHO. It would mean that we would have to handle any issues encountered with present
and future versions of crosstool-ng here in the forum. By
not relying on crosstool-ng, we
only have to handle problems with the cross-building process itself, and the occassional "why do I need a crosscompiler in the first place" question. I also think that the current way is more... instructive (no pun intended) as to what's really going on.
I don't say that these are "killer arguments", just that there are benefits to describing the "manual" path.

I'm pretty sure that if you're able to undestand and execute manual instructions in the wiki you will be qualified to check and even perhaps fix any crosstool-ng issues.
The opposite is not true.

I never intended to suggest that.

I can also see the value of the "weed-out" instructions. That answer is good enough for me for why not to mention it.
