From 42545ffbb37f2646a2a8c20999c21d3300e24f59 Mon Sep 17 00:00:00 2001 From: Mark Hatle Date: Fri, 22 Jun 2012 18:44:06 -0500 Subject: populate_sdk: enable basic multilib support In order to enable basic multilib support for the export of an SDK image, a number of minor changes had to be made: The value of MULTIMACH_TARGET_SYS needs to be variable. This way we can define the value to the appropriate multilib. (Also in some cases the default PACKAGE_ARCH is set to MACHINE_ARCH which is incorrect for the SDK.) Add a companion REAL_MULTIMACH_TARGET_SYS, based on code from meta-environment, to allow for this. We have to convert the do_populate_sdk into a python call, and then break up the previous items into three parts. * Image construction * Setup of environment files * Generation of the tarball Then we can iterate over the multilibs to populate the environment files. Finally, matching changes were needed in the toolchain-scripts file. And what I presume is an optimization of immediate evaluation for TOOLCHAIN_CONFIGSITE_NOCACHE and ..._SYSROOTCACHE needed to be done at runtime, otherwise the wrong values may be used.
