Summary: Use BR toolchain externally results a non-bootable
root filesystem
Product: buildroot
Version: 2014.05
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P5
Component: Other
AssignedTo: unassigned at buildroot.uclibc.org
ReportedBy: xxiao8 at fosiao.com
CC: buildroot at uclibc.org
Estimated Hours: 0.0
To reproduce(I used IMX6 board)
1. set HOST_DIR to wherever you want to relocate the toolchain.
2. make toolchain
3. build a rootfs using the above-built toolchain _externally_.
4. boot it up, you will find error saying "no init is found"
To fix it manually we need add a ld-linux.so.3 symlink under /lib on the rootfs
1. cd output/target/lib
2. ln -s ld-linux-armhf.so.3 ld-linux.so.3
3. boot with the modified rootfs
If we use internal buildroot toolchain directly, the ld-linux.so.3 is there. If
we use external buildroot toolchain, the ld-linux.so.3 was not created somehow.
