Adding libstdc++-dev path?

Adding libstdc++-dev path?

[Mauro Ziliani]

[-- Attachment #1: Type: text/plain, Size: 354 bytes --]

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?

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

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

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`)

Sorry. I sleep over the keyboard.

The solution is adding manually the location of /usr/include/c++/5.3.0 
/usr/include/c++/5.3.0/arm-poky-linux-gnueabi where library foldes.


Your recipe is usefull to test my problem


Thans.
