shouldn't extend to different multilibs, the kernel is one of them... 15404 2 mark.hatle 2011-08-11 09:14:15 +0000 This isn't a bug in the multilib system. The linux kernel can only be built with the "largest" endian available to the system. I.e. on x86_64, it must be built as x86_64. The remaining bug, if any, is simply a way to prevent certain packages from working in a multilib config. 15405 3 richard.purdie 2011-08-11 09:58:56 +0000 Simply raising SkipPackage in appropriate cases is likely the best solution. The kernel is specific enough that I'm happy for it to be coded against testing for inherit kernel or module-base and then picking the "larger" one. We'd probably have to code that 64 bit wins over 32 bit. 15483 4 ke.yu 2011-08-16 01:45:39 +0000 I've done a POC patch as below. then the bitbake lib32-core-image-sato will fail in parsing as expected, since virtual/lib32-kernel is not available. so i wonder if it is acceptable? If so, how should we test the lib32-core-image-sato?

The patch above is a work in progress though and I was only half way through writing it before travel interrupted the work. 15979 6 richard.purdie 2011-09-02 14:29:52 +0000 Fixed in master, http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=f9c3639238c2a9f1072e39ba26d0e521c5951b95
