Hi guys,
I tried to use eglibc as system library for my x86 box, so I modified
the conf/distro/minimal-eglibc.conf (see below for my changes). But
compiling eglibc failed with the message "undefined reference to
`__i686.get_pc_thunk.bx", The following is the raw error information. Who
can give me some hint.
ccache i586-oe-linux-gcc -march=i586 -nostdlib -nostartfiles -shared \
-Wl,-z,combreloc -Wl,-z,relro -Wl,--hash-style=both
-Wl,-z,defs -Wl,--verbose 2>&1 | \
LC_ALL=C \
sed -e '/^=========/,/^=========/!d;/^=========/d' \
-e 's/\. = 0 + SIZEOF_HEADERS;/& _begin = . -
SIZEOF_HEADERS;/' \
