[Unattended-Dev] Error compiling linuxboot/busybox

[Вячеслав П. <spe...@ma...>]

Hello!

I have got the following linking error compiling linuxboot:

linuxboot/busybox-1.15.3
networking/udhcp/lib.a(dhcpc.o): In function `udhcpc_main':
dhcpc.c:(.text.udhcpc_main+0x5e3): undefined reference to `__fdelt_chk'
networking/udhcp/lib.a(signalpipe.o): In function `udhcp_sp_fd_set':
signalpipe.c:(.text.udhcp_sp_fd_set+0x1d): undefined reference to `__fdelt_chk'
signalpipe.c:(.text.udhcp_sp_fd_set+0x42): undefined reference to `__fdelt_chk'
networking/udhcp/lib.a(signalpipe.o): In function `udhcp_sp_read':
signalpipe.c:(.text.udhcp_sp_read+0x10): undefined reference to `__fdelt_chk'

The reason is busybox/Makefile does not respect passed CFLAGS_EXTRA
This results in using headers from installed system-wide glibc 2.15 in my case

Maybe you should modify busybox/Makefile?
