Error: PATH contains '.' or '', which will break the build, please remove this.

Error: PATH contains '.' or '', which will break the build, please remove this.

[Axel Beierlein]

Hello,

when i start bitbake core-image-minimal i get the Error
"PATH contains '.' or '', which will break the build, please remove this."

But there is definitly no '' a whitespace or a point in my PATH.

What could be the reason for this Error?

Regards

Axel

That error could be phrased better...

If you don't have a . element, you probably have an empty element
(which is what the '' is trying to say).  For example:

/usr/bin:/bin::/home/ross/bin

The :: after /bin is bad, and it's this which needs to be removed.
This is normally due to bad concatenation when extending $PATH.

Actually it's probably worth printing out the parsed PATH when this
warning fires to help solve the problem, I've seen a few people hit
this recently and it's not obvious what the problem is sometimes.

Hello,

i've solved the Problem.
A few posts ago there was a hint with a trailing : in a PATH Var.
This was my Problem. Deleting the last : an it works!

This hint could be also integrated in the error message.

I'm working on a patch to display the parsed PATH so you'll see the
trailing empty element in that case.

How's this?

$ PATH=$PATH:
$ bitbake core-image-sato

It's still slightly hard to spot there. I wonder if something like
this would be easier for the user?

ERROR: Invalid PATH entry at character N: /usr/bin:/bin:

         ^

In other words, formatted like a syntax error.

That would be easier for the user, but harder to implement. :)

It'd be something like https://gist.github.com/3136618, no doubt.

But the problem is the assumption of the length of the prefix, that
is, assumption of the final formatting to the user, which isn't ideal.
What we should do, I think, is teach the UI log formatter to indent
subsequent lines based on its own prefix, so that "foo\nbar" would
show up like this:

ERROR: foo
             bar

Rather than:

ERROR: foo
bar
