Re: [Ltib] Dynamically setting which toolchain to use?

[Stuart Hughes]

Hi Mattias,

For toolchains outside LTIB it is right to use "custom" for the
toolchain selection.

The best thing to do is (once):

$ ./ltib -m config
# setup the custom toolchain to use your cross tools
# setup any other configuration points you want (packages etc)

# optionally build it to check it works
$ ./ltib

You now have a configuration file that you can use.  Save this off to a
handy name:

cp config/platform/<target>/defconfig.dev config/platform/<target>/<myname>

>From your makefile call:
<path>/ltib --preconfig <path>/config/platform/<target>/<myname> --batch

Regards, Stuart
