[yocto] Debugging a build issue in an isolated enviroment

[Alan Martinovic]

I'm just upgrading to pyro and have some issues with u-boot-fw-utils.

The error fails at do_compile stage which looks like this:

    do_compile () {
            oe_runmake ${UBOOT_MACHINE}
            oe_runmake env
    }


The error is:

Log data follows:

I would assume this is a to specific error to ask help about. It seems
that the compiler isn't being called correctly (it's called as cc,
which isn't the full compiler name).
Suggestions are welcome but that isn't the reason for my post.

Is there a way to run the above listed make command with the same
environment as it is run when the error is produced?

I have tried:

devtool modify  u-boot-fw-utils

but it doesn't bring me to an environment where I can reproduce the
error by executing the make call manually.
I get different non related errors:

make: invalid option -- 'a'
make: invalid option -- 'c'
make: invalid option -- '='
make: invalid option -- 'a'
make: invalid option -- '7'
make: invalid option -- 'c'
make: invalid option -- 'u'
make: invalid option -- '='

and the make I'm using comes from /usr/bin/make instead of somewhere from yocto.

Any ideas on how to approach?

Be Well,
Alan
