[Ltib] LTIB-11-4-1-SV Kernel Headers is not Installed

[Daniel Widyanto]

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.
