the toolchain setting in micro.conf is incompatible, which caused this
problem. For the preferred version of glibc is 2.6.1 which is set in
conf/distro/include/sane-toolchain.inc,
Isn't micro using eglibc? I wouldn't have expected that you should be
seeing glibc built at all for that DISTRO.
I set LIBC=glibc in shell environment.
I think it is better to change the
binutils preferred version which is set in conf/distro/micro.conf.
As I said before, binutils 2.18 is not acceptable in general because
this version cannot do Thumb code. Glibc 2.6.1 is pretty old and, if it
is incompatible with newer toolchains, I would suggest updating to a
newer version of glibc (e.g. 2.10) rather than trying to wind the
toolchain backwards.
Yes, I think so. Several days ago, I submitted a patch to update glibc to
2.10 in conf/distro/include/sane-toolchain.inc, but was rejected and the
reason was that it may break other buildings and had not full tested.
As a last resort we could make the binutils version be
architecture-specific, and select 2.18 for i386, but I really don't
think this ought to be necessary.
I agree with you
