<title>QA Error and Warning Messages</title>

    <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.

                    As mentioned, this list of error and warning messages is for
                    QA checks only.
                    The list does not cover all possible build errors or
                    warnings you could encounter.

                <listitem><para>
                    Because some QA checks are disabled by default, this list
                    does not include all possible QA check errors and warnings.

    <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.

                    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.

                    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>
                    for the package.
                    Another option is to check the
                    <link linkend='ref-tasks-compile'><filename>do_compile</filename></link>
                    log and verify that the compiler options being used

                    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

                    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.

                    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>

                    the private version of the library.

    <title>Configuring and Disabling QA Checks</title>

    <para>
        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>
        variables, respectively.
        You can also disable checks within a particular recipe using
        <link linkend='var-INSANE_SKIP'><filename>INSANE_SKIP</filename></link>.
        For information on how to work with the QA checks, see the
        "<link linkend='ref-classes-insane'><filename>insane.bbclass</filename></link>"
        section.
        <note><title>Tip</title>
            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.
