Hi all,
If link library of distribution which built by Yocto-1.4.x,
the following error will be caught.
#
/opt/poky-lsb/1.4.1/sysroots/x86_64-pokysdk-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gcc

collect2: error: ld returned 1 exit status
It can be avoid by changing the sysroot to "/opt/mydistro".

/opt/poky-lsb/1.4.1/sysroots/x86_64-pokysdk-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gcc
\
-o helloworld helloworld.c -L /usr/lib -l xxx --sysroot /opt/mydistro
The default sysroot is "/opt/poky-lsb/1.4.1/sysroots/x86_64-poky-linux",
but why cross gcc finds libc.so.6 from /opt/mydistro/
# cat /opt/poky-lsb/1.4.1/environment-setup-x86_64-poky-linux | grep sysroot
... ...
CC="x86_64-poky-linux-gcc -m64
--sysroot=/opt/poky-lsb/1.4.1/sysroots/x86_64-poky-linux"
... ...
Any suggestion?
Thanks
Bian
