several recipes give a link error: libc.so, needed by libgcc_s.so, not found

[Jay Snyder]

I am getting the following warning (I assume it is a warning, because 
they all seem to produce working executables) for several recipes 
(rxvt-unicode shown):

./rxvt-unicode-7.9-r1/temp/log.do_compile.9530:44:/home/oe/build-2010-07-29/tmp/sysroots/x86_64-linux/usr/lib/gcc/i686-angstrom-linux/4.3.3/../../../../i686-angstrom-linux/bin/ld: 
warning: libc.so, needed by 
/home/oe/build-2010-07-29/tmp/sysroots/x86_64-linux/usr/lib/gcc/i686-angstrom-linux/4.3.3/../../../../i686-angstrom-linux/lib/libgcc_s.so, 
not found (try using -rpath or -rpath-link)

The following recipes all exhibit this error:

qt4-x11-free-4.6.3-r19.2
gs-8.64-r2
schroedinger-1.0.9-r0
gtk+-2.20.1-r8.1
libsndfile1-1.0.21-r1
mysql-4.1.22-r6
libmusicbrainz-3.0.2-r1
cups-1.4.3-r2
rxvt-unicode-7.9-r1
gnutls-2.8.6-r10.0

Also, anything I attempt to build with the above mentioned qt4-x11-free 
also produce the same warning.

There is a file, libc.so in the 
/home/oe/build-2010-07-29/tmp/sysroots/i686-angstrom-linux/usr/lib path, 
which IS in an -Wl,rpath= argument being passed to gcc (or g++) (and 
subsequently to the linker).

This problem didn't occur on a git-pull from December 4, 2009, but does 
on a July 29,2010 pull.

Thanks,
Jay

I have seen the same message for libusb both with gcc 4.4.4 and 4.3.3
Note that libc.so is in usr/lib while the lib.so.6 file is in lib.
No idea if that is relevant.

libc.so contains:
frans@linux-suse:~/oe/tmp_angstrom/sysroots> cat
./armv7a-angstrom-linux-gnueabi/usr/lib/libc.so
/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a  AS_NEEDED (
/lib/ld-linux.so.3 ) )

No idea if these should be paths in sysroots (I'm not a dynamic linking expert).

is there a problem you run into because of this warning ?

If I remember correctly, you need to put the

TARGET_CC_ARCH += "${LDFLAGS}"

in the offending bb.

Hope this helps,

Any progress on this issue?

Meanwhile, adding "-L${STAGING_DIR_TARGET}${base_libdir}" (and perhaps
also a rpath-link directive) to TARGET_LDFLAGS in conf/bitbake.conf
could serve as a work-around.

I have
http://sourceware.org/bugzilla/show_bug.cgi?id=10340
applied locally to binutils, and it works.
