Forget about the DEPENDS, I used that in another scenario.

I tried the following recipe:

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI = "file://main.cpp"
do_compile() {

    # For example purpose use only

    ${CXX} ${CXXFLAGS} ${WORKDIR}/main.cpp -o ${B}/${PN}
}

With a simple main:

#include <iostream>
#include <cstdio>
int main(void) {
    printf("Hello from %s\n", __func__);
    return 0;
}

And it get built just fine (`bitbake libstdtest`)

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,

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?

Mauro
