To reproduce this with the bernard (binutils_2.21.bb) and OpenSuSe 11.4 which binutils-2.21-13.1.x86_64. The problem is when the sysinfo (host tool) is built within bintuils-2.21/build.blah/binutils directory, it gets an LD_LIBRARY_PATH that includes locally built libraries that are not compatible with the host system libraries. This command will reproduce the problem directly (clearly you need to modify the directories on for your system).

The build.blah/Makefile (which is generated from Makefile.in) has settings for a HOST_LIB_PATH which may not be correct, that a starting point for this bug. 17633 1 nitin.a.kamble 2011-12-13 16:45:26 +0000 Saul, Josh, I wonder why it does not hit non-suse x86-64 hosts. If you know any insight let me know. Thanks, Nitin 17634 2 nitin.a.kamble 2011-12-13 16:48:06 +0000 I guess it is coming from the matching binutils version on the host. Nitin 17642 3 sgw 2011-12-14 09:40:42 +0000 Correct, on other hosts, the binutils is either an older version or is installed using a different version or extension for example on ubuntu 2.21.53.20110810-0ubuntu5 had a date in the version string and therefore is not a match. 17776 4 nitin.a.kamble 2011-12-20 23:40:59 +0000 more findings: the problem is wrong LD_LIBRARIES_PATH while running distro gcc. poky sets : CC_FOR_BUILD = gcc which is correct, a distro gcc for compiling buildtime tools. And we have setup LD_LIBRARIES_PATH including build sysroots for do_compile, The solution is to not pass our LD_LIBRARIES_PATH while executing distro binaries.
