           Summary: build failure for angstrom-2008.1 with eglibc
           Product: Openembedded
           Version: Angstrom 2008.x
          Platform: ARM
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: org.openembedded.dev
        AssignedTo: openembedded-commits at lists.openembedded.org

Build fails for angstrom-2008.1 distribution with eglibc instead of glibc. 
Build fails during the eglibc linking stage - many undefined symbols related to
floating point operation. 

I tried two machines: at91sam9260ek and at91sam9g29ek. The following additional
options were specified in local.conf:

ANGSTROMLIBC = "eglibc"
ANGSTROM_MODE = “eglibc”
ANGSTROM_GCC_VERSION = "4.4.1"
ANGSTROM_BINUTILS_VERSION = "2.19.1"
PREFERRED_VERSION_glibc = "2.9"
PREFERRED_VERSION_eglibc = "2.9"


During investigation it turned out that target architecture for gcc was
incorrect: arm-angstrom-linux instead of arm-angstrom-linux-gnueabi. It looks
that the problem is in file conf/distro/include/angstrom-eglibc.inc. There are
two lines on top of this file:

TARGET_OS = "linux${@['','-gnueabi'][bb.data.getVar('TARGET_ARCH',d,1) in
['arm', 'armeb'] and bb.data.getVar('MACHINE',d) not in ['collie','h3600',
'h3800', 'simpad', 'htcwallaby']]}"

TARGET_OS = "linux${@['','-gnuspe'][bb.data.getVar('TARGET_ARCH',d,1) in
['ppc', 'powerpc'] and bb.data.getVar('MACHINE',d) in ['calamari']]}"

The first line sets the correct TARGET_OS="linux-gnueabi", but the second line
unconditionally overrides it with TARGET_OS="linux".

I tried to comment second line and build succeded.
