Stefan,
I did installed with ARCH=openrisc make INSTALL_HDR_PATH=${SYSROOT}/usr
headers_install
and have $SYSROOT set to /opt/or1k-toolchain/or1k-linux-uclibc/sys-root as
suggested by the instruction.
And I did installed the headers from git://
git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
I double checked everything again, and rebuild after make distclean, sill
getting the same error. Is it possible that the upstream linux version is
not compatible with the upstream uclibc version ? Or is there anything else
I can check to know if I did anything wrong ?
Thanks
Patrick
