Hi all,
I'm using ltib-11-4-1-sv to build linux-2.6.33 for EA3131 (Embedded Artist -
LPC3131) board, and I found out that the kernel headers are not installed
properly in rootfs/usr/src/linux/include. The LTIB kernel headers missed the
Makefile to build external modules. So the header files cannot be used to
compile external module / device drivers.
The common practice to install Linux-2.6 headers is to use 'make ARCH=arm
INSTALL_HDR_PATH=${header_dir} headers_install'. I've updated
'dist/lfs-5.1/kernel/kernel-common.tmpl' to include it:
----------------------------------
if [ -n "$PKG_KERNEL_WANT_HEADERS" ]
then
make ARCH=$LINTARCH HOSTCC="$BUILDCC"
INSTALL_HDR_PATH=$RPM_BUILD_ROOT/%{pfx}/usr/src/linux headers_install
# mkdir -p $RPM_BUILD_ROOT/%{pfx}/usr/src/linux/include
# for i in asm-${LINTARCH} asm-generic config linux math-emu media mtd net
pcmcia rxrpc scsi sound video
# do
# if [ -d include/$i ]
# then
# cp -a include/$i $RPM_BUILD_ROOT/%{pfx}/usr/src/linux/include
# fi
# done
#
# for i in asm config linux
# do
# if [ -d $KBOUT/include/$i ]
# then
# cp -a $KBOUT/include/$i
$RPM_BUILD_ROOT/%{pfx}/usr/src/linux/include
# fi
# done
#
# if [ "${LINTARCH}" = "arm" ]
# then
# if [ -d "$KBOUT/include/asm/arch" ]
# then
# mkdir -p $RPM_BUILD_ROOT/%{pfx}/usr/src/linux/include/asm/arch
# cp -a $KBOUT/include/asm/arch/*
$RPM_BUILD_ROOT/%{pfx}/usr/src/linux/include/asm/arch
# else
# echo "Don't know how to copy asm headers for this kernel"
# fi
# fi
fi
----------------------------------
However, in the rootfs/usr/src/linux/include, I still didn't see the Linux
Makefile that can be used to compile external modules.
