I try,

But libstdc++-dev is procudes by gcc-runtime recipe.

I try to put gcc-runtime in DEPENDS e RDEPENDS_${PN} but this doesn't.

Finally I put manually the -I${STAGING_INCDIR}/c++/5.3.0 -I${STAGING_INCDIR}/c++/5.3.0/${CC_PREFIX} in the Makefile.

CC_PREFIX=arm-poky-linux-gnueabi

Hi,

have you tried adding libstdc++-dev to the recipe dependencies?

DEPENDS += " libstdc++-dev"

This will bring libstdc++ package into recipe sysroot and no extra actions will be needed on compilation flags.

Regards,
Gabriele

    Hi all

    I'm trying to compile a library which need cstdio.

    The file is in ${STAGING_INCDIR}/c++/5.3.0 and in
    ${STAGING_INCDIR}/c++/5.3.0/tr1

    I think I need to "include" in my recipe all libstdc++dev package

    Looking on ${CXX} -v I get
    --with-gxx-include-dir=/not/exist/usr/include/c++/5.3.0


    How can I use stdc by recipe?
