Re: Cannot build a gcc cross-compiler

Hello all!

BTW, the canonical url for the mailing list is:

automake is needed to build some of the components of the toolchain.
So crosstool-NG checks for it.

If you don't have it, you'll have to install it anyway, even if you do
not use crosstool-NG.

I agree with you: there really is a lack of documentation on how to
properly build cross toolchains with the GNU tools.

That's why I tried to write crosstool-NG so that is is easy to follow
what is going on.

First, run: ct-ng list-steps

This will give you the list of steps that crosstool-NG follows to build
a toolchain. Then you can look at each step's build procedure to see how
that specific component is built. crosstool-NG is written as a collection
of bash scripts, so the code is directly readable.

Eventually, you'll end up learning the build procedure for a complete
toolchain, *and* you'll have it auto-generated for you.

PS. Of course, you might be able to learn as well with OSELAS.Toolchain,
    but I don't know that project, and it's much more complex as it also
    builds a complete system.
