6534 2014-07-14 22:18:02 +0000 Does the Yocto Project toolchain support 'multilib' (within the toolchain)? 2014-12-11 16:29:50 +0000 1 1 7 Build System, Metadata & Runtime OE-Core devtools / tool chain 1.7 x86 Multiple RESOLVED INVALID Medium normal 1.7 1 pangbw mark.hatle meta.mr.watcher meta.watcher poky.bs.watcher poky.watcher richard.purdie --- --- Yes (doc changes required) oldest_to_newest 44477 0 pangbw 2014-07-14 22:18:02 +0000 I am trying to build gcc-cross in 'multilib' mode under Yocto, I have tried many methods but without luck, I looked into the code and feel the 'multilib' is NOT supported at all though we can find some receipt files in the Yocto source tree. Can someone tell me if 'multilib' is supported or not at this point? If it is, please give me a simple steps to show how to do that. Thanks, Baoshan 44538 1 mark.hatle 2014-07-17 14:54:32 +0000 There are two difference concepts of the multilib within the Yocto Project. The primary usage is multiple toolchains (one per multilib) and multilib sysroots (again one per multilib). 'gcc-cross' does not support multilib configuration from what I understand. The question should really be about gcc-cross-canadian (this is the toolchain that is located within the generated SDK.) I believe the question is -- how are multilibs, within GCC enabled and used? My understanding is that baoshan wants to generate an SDK that uses a single gcc binary with multilibs enabled. 47518 2 richard.purdie 2014-12-11 16:29:50 +0000 If the question is whether we plan to make gcc-cross support multilib, we do not, that isn't the way multilib support in OE works. This isn't something we plan to change and the bug resolution would be WONTFIX. On the other hand, our builds do support multilib, as do our SDK and gcc-cross-canadian and so on so that would be WORKSFORME. If there is a specific issue to address please open a new bug or reopen this with the details.
