The QEMU recipe now uses a number of
|
||||
<link linkend='var-PACKAGECONFIG'><filename>PACKAGECONFIG</filename></link>
|
||||
options to enable various optional features.
|
||||
The method used to set defaults for these options means that
|
||||
existing
|
||||
<filename>local.conf</filename> files will need to be be
|
||||
modified to append to <filename>PACKAGECONFIG</filename> for
|
||||
<filename>qemu-native</filename> and
|
||||
<filename>nativesdk-qemu</filename> instead of setting it.
|
||||
In other words, to enable graphical output for QEMU, you should
|
||||
now have these lines in <filename>local.conf</filename>:
|
||||
<literallayout class='monospaced'>
|
||||
PACKAGECONFIG_append_pn-qemu-native = " sdl"
