built and installed an image on a T4240RDB, g++ is misconfigured.

[nickcaruso]

I think this is a bug in the 1.9 SDK:  I added some things to the local.conf file

MACHINE ??= 't4240rdb-64b'

DISTRO ?= 'fsl-qoriq'

#PACKAGE_CLASSES ?= "package_rpm"

    ABORT,${SSTATE_DIR},100M,1K"

PACKAGECONFIG_append_pn-qemu-native = " sdl"

PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

ASSUME_PROVIDED += "libsdl-native"

CONF_VERSION = "1"

BB_NUMBER_THREADS = "2"

PARALLEL_MAKE = "-j 2"

DL_DIR = "/home/nxp/SDK/QorIQ-SDK-V1.9-20151210-yocto/downloads"

SSTATE_DIR = "/home/nxp/SDK/QorIQ-SDK-V1.9-20151210-yocto/sstate-cache"

INHERIT += "own-mirrors"

SOURCE_MIRROR_URL ?= "http://git.freescale.com/source/"

##SSTATE_MIRRORS = "file://.*/(.*)/(.*) file://${SSTATE_DIR}/native/\1/\2 \n"

SSTATE_PKG_SUFFIX = "txz"

SSTATE_PKG_TARZIPPROG = "xz"

ACCEPT_FSL_EULA = ""

# Parallelism Options

BB_NUMBER_THREADS = "3"

PARALLEL_MAKE = "-j 3"

DL_DIR = "/home/nxp/SDK/QorIQ-SDK-V1.9-20151210-yocto/downloads"

SSTATE_DIR = "/home/nxp/SDK/QorIQ-SDK-V1.9-20151210-yocto/sstate-cache"

INHERIT += "own-mirrors"

SOURCE_MIRROR_URL ?= "http://git.freescale.com/source/"

##SSTATE_MIRRORS = "file://.*/(.*)/(.*) file://${SSTATE_DIR}/native/\1/\2 \n"

# use xz to compress sstate

SSTATE_PKG_SUFFIX = "txz"

SSTATE_PKG_TARZIPPROG = "xz"

and ran "bitbake fsl-image-full", then installed the resulting image on a sata hard drive, booted my T4240RDB from it, and tried to compile the following source:

(file name tc.cpp):

#include <cmath>

#include <iostream>

using namespace std;

int main(){

  cout<<"hello"<<endl;

  return 0;

}

Here is the output of g++ -v tc.cpp:

imagenav@t4240rdb:~$ g++ -v tc.cpp

Using built-in specs.

You can see it's got some sort of misconfiguration in the search paths for the includes.  Is this a bug?  I don't see how I did anything that could cause this problem.

Quick workaround: use double slash for sysroot.

g++ --sysroot=// -v -o tc tc.cpp

Issue of broken sysroot for toolchains that have been configured with sysroot of / was discussed here:

Re: [patch] avoid '//' prefixes when sysroot is set to '/'

But that patch was not applied for gcc recipes in meta-freescale (sources/meta-freescale/recipes-devtools/gcc)

I see that one part of that patch is applied in poky upstream, though (sources/poky/meta/recipes-devtools/gcc/gcc-4.9/0040-fix-g++-sysroot.patch).

[nickcaruso]

I eventually managed to apply the patch to the compiler and rebuild the system image for my development machine. Seems like this patch ought to eventually be applied by default - perhaps in the next SDK rev?

[esoule]

In the meantime, to avoid patching and rebuilding the toolchain, I created a wrapper script on the target. The script below automates the process:

#!/bin/sh

set -x

set -e

if [ -e "/usr/bin/powerpc64-fsl-linux-g++.real" ] ; then

    exit 0

fi

if [ ! -e "/usr/bin/powerpc64-fsl-linux-g++" ] ; then

    exit 1

fi

cat <<"__EOF__" >"/usr/bin/powerpc64-fsl-linux-g++.wrapper"

#!/bin/sh

exec "/usr/bin/powerpc64-fsl-linux-g++.real" --sysroot=//// "$@"

__EOF__

chmod a+x "/usr/bin/powerpc64-fsl-linux-g++.wrapper"

mv "/usr/bin/powerpc64-fsl-linux-g++" "/usr/bin/powerpc64-fsl-linux-g++.real"

mv "/usr/bin/powerpc64-fsl-linux-g++.wrapper" "/usr/bin/powerpc64-fsl-linux-g++"

This allows me to compile with C++ compiler without passing the sysroot parameter to the CXX variable for the build system.

Trying to re-install gcc using smart.  I have lighttpd serving the rpms, configured smart to see the channels, but when I ask smart to commit the re-install, it says "rpm unavailable for download".

On a whim, tried "smart --shell" and used the "check" command as "check gcc" and got the following:

smart> check gcc

Do I need to install this lib32_ppce6500 stuff?
