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

    <title>Introduction</title>

    <para>
        Fixing QA issues in your recipes can take significant time and effort
        when writing new recipes.
        Sometimes you might be tempted to ignore a QA message or even to
        disable these QA checks.
        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.
        <note>

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

                Thus, installing to <filename>/usr/libexec</filename>
                is likely not desirable.

                </literallayout>
                The specified binary produced by the recipe contains dynamic
                library load paths (rpaths) that contain build system paths
                such as
                <link linkend='var-TMPDIR'><filename>TMPDIR</filename></link>,
                which could potentially be a security issue.
                Check for bad <filename>-rpath</filename> options being passed

                Depending on the build system used by the software being built,

                The specified binary produced by the recipe contains dynamic
                library load paths (rpaths) that on a standard system are
                searched by default by the linker (e.g.
                <filename>/lib</filename> and <filename>/usr/lib</filename>).
                While these paths will not cause any breakage, they do waste
                space and are unnecessary.
                Depending on the build system used by the software being built,
                there might be a configure option to disable rpath usage
                completely within the build of the software.

                Symlink <filename>.so</filename> files are for development
                only, and should therefore go into the
                <filename>-dev</filename> package.
                This situation might occur if you add
                <filename>*.so*</filename> rather than
                <filename>*.so.*</filename> to a non-dev package.

     &lt;packagename&gt;: found library in wrong location [libdir]

                The specified file may have been installed into an incorrect
                (possibly hardcoded) installation path.
                For example, this test will catch recipes that install
                <filename>/lib/bar.so</filename> when
                <filename>${base_libdir}</filename> is "lib32".
                Another example is when recipes install
                <filename>/usr/lib64/foo.so</filename> when
                <filename>${libdir}</filename> is "/usr/lib".
                False positives occasionally exist.
                For these cases add "libdir" to
                <link linkend='var-INSANE_SKIP'><filename>INSANE_SKIP</filename></link>
                for the package.

                The convention within the OpenEmbedded build system is for
                package names (sometimes enforced by the package manager itself)
                to require that package names are all lower case and to
                allow a restricted set of characters.
                If your recipe name does not match this, or you add packages
                to
                <link linkend='var-PACKAGES'><filename>PACKAGES</filename></link>
                that do not conform to the convention, then you will receive
                this error.
                Rename your recipe.
                Or, if you have added a non-conforming package name to
                <filename>PACKAGES</filename>, change the package name
                appropriately.

     File '&lt;file&gt;' from &lt;recipename&gt; was already stripped, this will prevent future debugging! [already-stripped]
                </literallayout>
                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.
                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.
