[yocto] Using a native tool from another recipe

[Gabriele Zampieri]

Hi all,

I need to add a couple of tools to my build system (build2 and odb). The
second one depends on the first. Following a snippet of the build2 recipe:
--------------------------------------------------------------------------------------------
DEPENDS = "openssl-native"
SRC_URI = "https://download.build2.org/${PV}/build2-toolchain-${PV}.tar.gz"
SRC_URI[sha256sum] =
"42a254c46b59109b764afade0d50819b3d793a9167f46759fc6aa9d6d8a6ff37"

S = "${WORKDIR}/build2-toolchain-${PV}"

# build.sh located inside the tarball cannot be used to configure, compile
and
# install in different steps. This task is misleading, but I didn't find any
# other way to make it works
do_compile_prepend() {
    ./build.sh --timeout 600 --sudo false \
        --make ${MAKE} ${PARALLEL_MAKE} \
        --trust yes \
        --install-dir ${prefix} g++
}

FILES_${PN}_append_class-nativesdk = " ${SDKPATHNATIVE}"
FILES_${PN} = "${D}${prefix}/*"

BBCLASSEXTEND = "native nativesdk"
--------------------------------------------------------------------------------------------

Then the odb-compiler recipe

--------------------------------------------------------------------------------------------
SECTION = "devtools"
DEPENDS = "build2-native"
CONFIG_NAME = "odb-gcc-X"
do_configure() {
    cd ${B}
    bpkg create -d ${CONFIG_NAME} cc    \
        config.cxx=g++                  \
        config.cc.coptions=-O3          \
        config.bin.rpath=/usr/lib       \
        config.install.root=/usr        \
        config.install.sudo=false

}
BBCLASSEXTEND = "native nativesdk"
--------------------------------------------------------------------------------------------

When I try to build odb-compiler, bitbake complete the build2-native
recipe, but fails on do_configure due to 'bpkg command not found'.

Are my recipes correct?

Thanks,
Gabriele
