[yocto] how to set LICENSE for llvm in .bb file

[Guo, Yejun]

Hi Randy,

See below for the .bb file that Juan and I created to build llvm+clang 3.3, one thing need to mention is that we do not put llvm-config under crossscripts (the .bb file in oe-core does so) since we want the same behavior between yocto build on host and direct build on target.

LICENSE = "NCSA"
DEPENDS = "libffi libxml2"

SRC_URI = "http://llvm.org/releases/${PV}/llvm-${PV}.src.tar.gz;name=llvm"
SRC_URI += "http://llvm.org/releases/${PV}/cfe-${PV}.src.tar.gz;apply=no;name=clang"
SRC_URI[llvm.md5sum] = "40564e1dc390f9844f1711c08b08e391"
SRC_URI[llvm.sha256sum] = "68766b1e70d05a25e2f502e997a3cb3937187a3296595cf6e0977d5cd6727578"
SRC_URI[clang.md5sum] = "8284891e3e311829b8e44ac813d0c9ef"
SRC_URI[clang.sha256sum] = "b1b55de4ab3a57d3e0331a83e0284610191c77d924e3446498d9113d08dfb996"

S = "${WORKDIR}/llvm-${PV}.src"
LIC_FILES_CHKSUM = "file://${S}/LICENSE.TXT;md5=d0a3ef0d3e0e8f5cf59e5ffc273ab1f8"

inherit cmake pkgconfig python-dir pythonnative

LLVM_BUILD_DIR = "${S}/build"

OECMAKE_SOURCEPATH = ".."
OECMAKE_BUILDPATH = "build"
do_unpack() {
    tar -xf ${DL_DIR}/llvm-${PV}.src.tar.gz -C ${WORKDIR}
    tar -xf ${DL_DIR}/cfe-${PV}.src.tar.gz -C ${S}/tools
    mv ${S}/tools/cfe-${PV}.src ${S}/tools/clang
}

do_configure() {
    mkdir -p ${LLVM_BUILD_DIR}
    cd ${LLVM_BUILD_DIR}
    cmake \
                .. \
                -DCMAKE_INSTALL_PREFIX:PATH=/usr \
                -DCMAKE_INSTALL_SO_NO_EXE=0 \
                -DCMAKE_TOOLCHAIN_FILE=${WORKDIR}/toolchain.cmake \
                -DCMAKE_VERBOSE_MAKEFILE=1 \
                -Wno-dev
}

do_compile() {
    cd ${LLVM_BUILD_DIR}
    oe_runmake llvm-tblgen
    oe_runmake clang-tblgen
    oe_runmake
}

SYSROOT_PREPROCESS_FUNCS += "llvm_sysroot_preprocess"

llvm_sysroot_preprocess() {
    install -d ${SYSROOT_DESTDIR}${bindir}
    install -m 0755 ${LLVM_BUILD_DIR}/bin/llvm-config ${SYSROOT_DESTDIR}${bindir}/llvm-config
    install -m 0755 ${LLVM_BUILD_DIR}/bin/llvm-as ${SYSROOT_DESTDIR}${bindir}/llvm-as
    install -m 0755 ${LLVM_BUILD_DIR}/bin/llvm-link ${SYSROOT_DESTDIR}${bindir}/llvm-link
    install -m 0755 ${LLVM_BUILD_DIR}/bin/clang ${SYSROOT_DESTDIR}${bindir}/clang
}

FILES_${PN}-dev += " ${libdir}/BugpointPasses.so \
                     ${libdir}/LLVMHello.so \
                     ${libdir}/clang  \
                   "

Thanks
Yejun

Yejun,

Did you ever produce a recipe to build clang?

Are you also trying to build all of YP with it?

A student that worked with me did some work to use clang to build yocto packages:

http://lists.openembedded.org/pipermail/openembedded-core/2013-November/086275.html

so I'd be interested in hearing about your work.
