I tried ldd-ing my binary on my build machine since it doesn't work on my image and it was built on glibc indeed. Since yocto is based on ulibc so it won't work even my target platform is roughly the same as my build platform. I wonder what options should I specify to get llvm to build against the Yocto's libraries rather than my build machine's.
As I said in IRC yesterday I found https://lists.yoctoproject.org/pipermail/yocto/2014-June/020358.html which should suit my needs but I get stupid errors on uint32_t: /work/corei7-64-poky-linux/llvm/3.3-r0/llvm -3.3.src/include/llvm/Support/BranchProbability.h:27:3: error: 'uint32_t' does not name a type uint32_t N; I tried adding #include <cstdint> to that header but no luck. -----Original Message----- From: Paul Eggleton [mailto:paul.eggle...@linux.intel.com] Sent: Monday, December 22, 2014 7:22 PM To: Yu, Chan KitX Cc: 'Liviu Gheorghisan'; 'Jim Rafert'; yocto@yoctoproject.org Subject: Re: [yocto] Building clang with Yocto Hi Chan Kit, On Monday 22 December 2014 03:33:17 Yu, Chan KitX wrote: > Here's an update FYI.

That sounds a bit like the binary has been linked to libraries in the host libdir rather than the correct one for the target. You may be able to verify that using ldd.
