[OE-core] [PATCH 1/8] multilib: Add support for compiling recipes against multiple ABIs
Richard Purdie
richard.purdie at linuxfoundation.org
Tue Jul 26 21:53:08 UTC 2011
This patch adds the core multilib class which can be used along with a
parameter specifying the mutlilib to use in BBCLASSEXTEND.
The MLPREFIX variable is added and can be used in cases where its too
difficult to dynmaically work out where a mutltilib prefix is needed
to be added to a variable.
This includes:
* SHLIBSDIR and PACKAGE_ARCH fixes from Lianhao Lu.
* PACKAGE_DYNAMIC mapping from Yu Ke
* PACKAGE_INSTALL mapping from Yu Ke
* RPROVIDES mapping from Yu Ke
* TARGET_VENDOR fix from Mark Hatle
* Ignorning *-native-runtime dependnecies as well as *-native from Yu Ke
