9595 If you want to force a particular version of a recipe, 9595 Sometimes the <filename>PREFERRED_VERSION</filename>
9596 you can use "forcevariable" as follows: 9596 variable can be set by configuration files in a way that
9597 is hard to change.
9598 You can use
9599 <link linkend='var-OVERRIDES'><filename>OVERRIDES</filename></link>
9600 to set a machine-specific override.
9601 Here is an example:
9597 <literallayout class='monospaced'> 9602 <literallayout class='monospaced'>
9598 PREFERRED_VERSION_linux-yocto_forcevariable = "3.4%" 9603 PREFERRED_VERSION_linux-yocto_qemux86 = "3.4%"
9599 </literallayout> 9604 </literallayout>
9600 Another method is to use a machine override: 9605 Although not recommended, worst case, you can also use the
9606 "forcevariable" override, which is the strongest override
9607 possible.
9608 Here is an example:
9601 <literallayout class='monospaced'> 9609 <literallayout class='monospaced'>
9602 PREFERRED_VERSION_linux-yocto_qemux86 = "3.4%" 9610 PREFERRED_VERSION_linux-yocto_forcevariable = "3.4%"
