<title>QA Error and Warning Messages</title>
<section id='qa-introduction'>
<title>Introduction</title>
<para>
When building a recipe, the OpenEmbedded build system performs
various QA checks on the output to ensure that common issues are
detected and reported.
Sometimes when you create a new recipe to build new software,
it will build with no problems.
When this is not the case, or when you have QA issues building any
software, it could take a little time to resolve them.
</para>
<para>
While it is tempting to ignore a QA message or even to
disable QA checks, it is best to try and resolve any
reported QA issues.
This chapter provides a list of the QA messages and brief explanations
of the issues you could encounter so that you can properly resolve
problems.
</para>
<para>
The next section provides a list of all QA error and warning
messages based on a default configuration.
Each entry provides the message or error form along with an
explanation.

<title>Errors and Warnings</title>
<!--
This section uses the <para><code> construct to enable permalinks for the
various QA issue and warning messages. The file templates/qa-code-permalinks.xsl
is used to locate the construct and generate the permalink. This solution
leverages the fact that right now this section in the ref-manual is the only
place is all the YP docs that uses the <para><code> construct. If, in the
future, that construct were to appear in the ref-manual, a generic permalink
would be generated for the text between <code></code>. If a better solution
can be found then it should be implemented. I can't find one at the moment.

space and are unnecessary.

<para>
A runtime dependency exists between the two specified
packages, but there is nothing explicit within the recipe
to enable the OpenEmbedded build system to ensure that
dependency is satisfied.
This condition is usually triggered by an
<link linkend='var-RDEPENDS'><filename>RDEPENDS</filename></link>
value being added at the packaging stage rather than up
front, which is usually automatic based on the contents of
the package.
In most cases, you should change the recipe to add an
explicit <filename>RDEPENDS</filename> for the dependency.

Architecture did not match (&lt;machine_arch&gt; to &lt;file_arch&gt;) on &lt;file&gt; [arch]

<para>
By default, the OpenEmbedded build system checks the
Executable and Linkable Format (ELF) type, bit size, and
endianness of any binaries to ensure they match the
target architecture.
This test fails if any binaries do not match the type since
there would be an incompatibility.
The test could indicate that the wrong compiler or compiler
options have been used.
Sometimes software, like bootloaders, might need to
bypass this check.
If the file you receive the error for is firmware
that is not intended to be executed within the target
operating system or is intended to run on a separate
processor within the device, you can add "arch" to
<link linkend='var-INSANE_SKIP'><filename>INSANE_SKIP</filename></link>

The specified ELF binary contains relocations in its

This situation can result in a performance impact
at runtime.
</para>

Typically, the way to solve this performance issue is to
add "-fPIC" or "-fpic" to the compiler command-line
options.
For example, given software that reads
<link linkend='var-CFLAGS'><filename>CFLAGS</filename></link>
when you build it, you could add the following to your
recipe:
<literallayout class='monospaced'>
CFLAGS_append = " -fPIC "

A common workaround for this situation is to pass in

The specified package contains an Xorg driver, but does not

The xserver-xorg recipe provides driver ABI names.
All drivers should depend on the ABI versions that they have

Driver recipes that include

If you are unsure, consult the upstream build
documentation, the
<filename>./configure --help</filename> output,
and the upstream change log or release notes.

change is, you can update
<link linkend='var-EXTRA_OECONF'><filename>EXTRA_OECONF</filename></link>
or the individual

<para>
The specified recipe has a name
(<link linkend='var-PN'><filename>PN</filename></link>)
value that appears in
<link linkend='var-OVERRIDES'><filename>OVERRIDES</filename></link>.
If a recipe is named such that its <filename>PN</filename>
value matches something already in
<filename>OVERRIDES</filename> (e.g. <filename>PN</filename>
happens to be the same as
<link linkend='var-MACHINE'><filename>MACHINE</filename></link>
or
<link linkend='var-DISTRO'><filename>DISTRO</filename></link>),
it can have unexpected consequences.
For example, assignments such as
<filename>FILES_${PN} = "xyz"</filename> effectively
turn into <filename>FILES = "xyz"</filename>.
Rename your recipe (or if <filename>PN</filename> is being
set explicitly, change the <filename>PN</filename> value) so
that the conflict does not occur.

<link linkend='var-FILES'><filename>FILES</filename></link>

<code>
File '&lt;file&gt;' from &lt;recipename&gt; was already stripped, this will prevent future debugging! [already-stripped]
</code>
</para>
<para>
Produced binaries have already been stripped prior to the
build system extracting debug symbols.
It is common for upstream software projects to default to
stripping debug symbols for output binaries.
In order for debugging to work on the target using
<filename>-dbg</filename> packages, this stripping must be
disabled.
</para>
<para>
Depending on the build system used by the software being
built, disabling this stripping could be as easy as
specifying an additional configure option.
If not, disabling stripping might involve patching
the build scripts.
In the latter case, look for references to "strip" or
"STRIP", or the "-s" or "-S" command-line options being
specified on the linker command line (possibly
through the compiler command line if preceded with "-Wl,").
<note>
Disabling stripping here does not mean that the final
packaged binaries will be unstripped.
Once the OpenEmbedded build system splits out debug
symbols to the <filename>-dbg</filename> package,
it will then strip the symbols from the binaries.

This message means that both

You can expect this message when a recipe has been renamed.
However, if that is not the case, the message might indicate
that a private version of a library is being erroneously
picked up as the provider for a common library.
If that is the case, you should add the library's
<filename>.so</filename> file name to
<link linkend='var-PRIVATE_LIBS'><filename>PRIVATE_LIBS</filename></link>
in the recipe that provides
the private version of the library.

You can configure the QA checks globally so that specific check
failures either raise a warning or an error message, using the
<link linkend='var-WARN_QA'><filename>WARN_QA</filename></link> and
<link linkend='var-ERROR_QA'><filename>ERROR_QA</filename></link>

You can also disable checks within a particular recipe using

For information on how to work with the QA checks, see the
"<link linkend='ref-classes-insane'><filename>insane.bbclass</filename></link>"

Please keep in mind that the QA checks exist in order to
detect real or potential problems in the packaged output.
So exercise caution when disabling these checks.
