I added following to my local.conf: LINUX_LIBC_HEADERS_VERSION = "2.6.37" and then rebuilt the whole packages (after "rm -rf tmp/"). Unfortunately result is same. Either I'm doing something wrong somewhere or eglibc + gcc 4.5 + 2.6.37 config is broken. Now I'm building all with following in my config: ANGSTROMLIBC = "glibc" ANGSTROM_GCC_VERSION = "4.4" I'll report the results.
