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.

[Axel Beierlein]

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?

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

Hi,
     I just updated my yocto repos and tried a fresh build.

My bblayers.conf file looks like this:

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "4"

BBFILES ?= ""

  /tool/yocto/meta-openembedded/meta-oe \
  /tool/yocto/meta-xilinx \
  "

And when I run the bitake core-image-minimal;bitbake meta-toolchain  I get the following errors:

The above is a warning, it is a configuration problem with one or more 
layer.conf file within a layer.  But it's a warning, the build will continue.

The above is an error.  Your shell environment's "PATH" is broken.  You have 
either '' (blank) or '.' within your path.

Run the following in your shell: echo "${PATH}"

If you see something like:

/usr/bin:/bin:~/bin:.

It's the '.' that is the problem.  Rewrite your path by removing the '.' item.. 
(similarly if it contains '::' or ends with ':' that is the blank problem)

I also started receiving this error about a week ago, my path is as follows:

[jack@archHP r0005]$ echo "${PATH}"
/home/jack/Projects/poky-denzil.git/scripts:/home/jack/Projects/poky-denzil.git/bitbake/bin/:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/bin/core_perl

However (from what I can see) this doesn't feature the issue mentioned?

It shows the following:

BBPATH="/tool/yocto/poky/meta-yocto::/tool/yocto/poky/meta:/tool/yocto/meta-openembedded/meta-oe:/tool/yocto/meta-xilinx"

There is an extra colon : , how can I remove it?

BBLAYERS above meta appears before meta-yocto but in BBPATH meta-yocto
appears before meta. I think meta-yocto/conf/layer.conf has

BBPATH := "${LAYERDIR}:${BBPATH}"

change it to

BBPATH .= ":${LAYERDIR}"

and if you want meta-yocto to appear before meta then rearrange
BBLAYERS above to

BBLAYERS ?= " \
 /tool/yocto/poky/meta-yocto \
 /tool/yocto/poky/meta \
 /tool/yocto/meta-openembedded/meta-oe \
 /tool/yocto/meta-xilinx \
 "

but that may not solve the problem too since now you will get

BBPATH=":/tool/yocto/poky/meta-yocto:/tool/yocto/poky/meta:/tool/yocto/meta-openembedded/meta-oe:/tool/yocto/meta-xilinx"

and it will whine about : at the beginning since that will present and
empty BBPATH when it separates them out for sanity checks.

The fix would be to see if you have : at beginning or end of BBPATH
(_after_ it has been populated) and strip it out.

Hi Khem,
                   I noticed that my PATH variable had an extra colon :  , once I fixed that, bitbake starts to work.

However, I still get the following warnings:

WARNING: BBPATH references the current directory, either through an empty entry, or a '.'.
	 This is unsafe and means your layer configuration is adding empty elements to BBPATH.
	 Please check your layer.conf files and other BBPATH settings to remove the current working directory references.

How can I fix this?

The output of the following command is empty

$ bitbake -e core-image-minimal | grep -e "^BBPATH="

$

I don't know what to do, to diagnose the problem and get rid of the warning.

Best regards,
