[yocto] yocto build cross toolchain issue

[Chandra Mishra (chanmish)]

Hi,

I build cross toolchain for corei7-64 arch based processor and getting build issue with the toolchain. Toolchain reports below error while linking static libraries,

  -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -static -lnsl -lpthread -lm -lrt

<TOOLCHAIN_PATH>/sysroots/corei7-64-poky-linux/usr/lib/../lib/librt.a(shm_open.o): In function `shm_open':

<SDK BUILD PATH>/build/tmp/work/corei7-64-poky-linux/glibc/2.22-r0/git/rt/../sysdeps/posix/shm_open.c:35: undefined reference to `__shm_directory'

<TOOLCHAIN_PATH>/sysroots/corei7-64-poky-linux/usr/lib/../lib/librt.a(shm_unlink.o): In function `shm_unlink':

<SDK BUILD PATH>/build/tmp/work/corei7-64-poky-linux/glibc/2.22-r0/git/rt/../sysdeps/posix/shm_unlink.c:35: undefined reference to `__shm_directory'

collect2: error: ld returned 1 exit status

 What could be the possible reason for above errors ?
