The background here is that we encountered many painful build problems with qt-4.7 on mips64 in oe-core-1.2. We tried to fix them initially but investigations from 6 months ago indicated that the qt upstream did not support mips64. Kai will dig into the current situation but I expect that little will have changed. We ended up with horrid bbapends such as: --- #Valid for all arches except mips64 with 64bit userspace # mips64 with n32 has host: mips64-wrs-linux-gnun32 # mips64 with n64 has host: mips64-wrsmllib64-linux # qemumips has host: mips-wrs-linux # qemumips-64 has host: mips64-wrs-linux COMPATIBLE_HOST = '((x86_64.*|i.86.*|powerpc.*|arm.*|mips-.*|mips32.*)-linux|mips64.*-linux-gnun32)' --- so we'll likely need a clue on how to declare a host as incompatible or introduce an INCOMPATIBLE_HOST variable. // Randy > > Regards, > Kai > >> >> Cheers, >> Paul >> > > -- # Randy MacLeod.
