Thanks, Richard. That's what I thought it is. Essentially, the includes are, as expected, resolved at parse time of the recipes, which makes entirely sense. The include files themselves conditionally set SRC_URI for patchsets which are evaluated when the recipes eventually is executed. While the conditional include is neat for keeping things separate, a solution might be to combine the two include files into one.On Tue, 2021-01-26 at 09:00 -0800, Rudolf J Streif wrote:I have been scratching my head over building openjdk-8 with multilib for an aarch64 system. Essentially, I want to use 32-bit OpenJDK on the 64-bit system.Theoretically adding to local.conf require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "armv7a" and then building lib32-openjdk-8 should do the trick. However, it does not: $ bitbake lib32-openjdk-8 <omitted> ERROR: Nothing PROVIDES 'lib32-openjdk-8' lib32-openjdk-8 was skipped: incompatible with host arm-fslcmllib32-linux-gnueabi (not in COMPATIBLE_HOST) The openjdk-8 recipe sets architecture dependency by selectively including an include file: INC_FILE_SUFFIX = "" INC_FILE_SUFFIX_aarch64 = "-aarch64" INC_FILE_SUFFIX_armv7a = "-aarch32" INC_FILE_SUFFIX_armv7ve = "-aarch32" require openjdk-8-release${INC_FILE_SUFFIX}.inc require openjdk-8-cross.incI suspect that at this point in the parse, the mulitlib code hasn't swizzled the bits around so it still looks like the main lib rather than the mutlilib. Including a variable in a require like that is an immediate expansion operation so it can't be "undone" when things get properly setup later. Offhand I'm not sure what you'd do to avoid this. The multilibs are all a bit ugly in some ways. It suggests they need to be setting up the overrides earlier. The assumption in the code is that people don't use immediate expansion for this reason.
