    <title>Using the SDK Toolchain Directly</title>

    <para>
        You can use the SDK toolchain directly with Makefile,
        Autotools, and <trademark class='trade'>Eclipse</trademark> based
        projects.
        This chapter covers information specific to each of these types of
        projects.

        <title>Autotools-Based Projects</title>

        <para>
            Once you have a suitable cross-toolchain installed, it is very easy
            to develop a project outside of the OpenEmbedded build system.
            This section presents a simple "Helloworld" example that shows how
            to set up, compile, and run the project.

                        As described earlier in the manual, installing the
                        cross-toolchain creates a cross-toolchain
                        environment setup script in the directory that the SDK
                        was installed.
                        Before you can use the tools to develop your project,
                        you must source this setup script.
                        The script begins with the string "environment-setup"
                        and contains the machine architecture, which is
                        followed by the string "poky-linux".
                        Here is an example that sources a script from the
                        default SDK installation directory that uses the
                        32-bit Intel x86 Architecture and the

                        Running the command prints the architecture on which

                        This architecture should be the same architecture that

            <title>Passing Host Options</title>

            <para>
                For an Autotools-based project, you can use the cross-toolchain
                by just passing the appropriate host option to
                <filename>configure.sh</filename>.
                The host option you use is derived from the name of the
                environment setup script found in the directory in which you
                installed the cross-toolchain.
                For example, the host option for an ARM-based target that uses
                the GNU EABI is <filename>armv5te-poky-linux-gnueabi</filename>.
                You will notice that the name of the script is
                <filename>environment-setup-armv5te-poky-linux-gnueabi</filename>.
                Thus, the following command works to update your project and
                rebuild it using the appropriate cross-toolchain tools:
                <literallayout class='monospaced'>
     $ ./configure --host=armv5te-poky-linux-gnueabi \
        --with-libtool-sysroot=<replaceable>sysroot_dir</replaceable>
                </literallayout>
                <note>
                    If the <filename>configure</filename> script results in
                    problems recognizing the
                    <filename>--with-libtool-sysroot=</filename><replaceable>sysroot-dir</replaceable>
                    option, regenerate the script to enable the support by
                    doing the following and then run the script again:
                    <literallayout class='monospaced'>
     $ libtoolize --automake
     $ aclocal -I ${OECORE_TARGET_SYSROOT}/usr/share/aclocal [-I <replaceable>dir_containing_your_project-specific_m4_macros</replaceable>]
     $ autoconf
     $ autoheader
     $ automake -a
                    </literallayout>
                </note>

        <title>Makefile-Based Projects</title>

        <para>
            For Makefile-based projects, the cross-toolchain environment
            variables established by running the cross-toolchain environment
            setup script are subject to general <filename>make</filename>
            rules.
        </para>

        <para>
            To illustrate this, consider the following four cross-toolchain
            environment variables:
            <literallayout class='monospaced'>
     <ulink url='&YOCTO_DOCS_REF_URL;#var-CC'>CC</ulink>=i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/&DISTRO;/sysroots/i586-poky-linux

            </literallayout>
            Now, consider the following three cases:

                    <emphasis>Case 1 - No Variables Set in the

                    Because these variables are not specifically set in the
                    <filename>Makefile</filename>, the variables retain their
                    values based on the environment.

                    Specifically setting variables in the
                    <filename>Makefile</filename> during the build results in
                    the environment settings of the variables being

                    Executing the <filename>Makefile</filename> from the
                    command-line results in the variables being overwritten
                    with command-line content regardless of what is being set
                    in the <filename>Makefile</filename>.
                    In this case, environment variables are not considered
                    unless you use the "-e" flag during the build:
                    <literallayout class='monospaced'>
     $ make -e <replaceable>file</replaceable>
                    </literallayout>
                    If you use this flag, then the environment values of the
                    variables override any variables specifically set in the

                When you install and configure the Eclipse Yocto Project
                Plug-in into the Eclipse IDE, you maximize your Yocto
                Project experience.
                Installing and configuring the Plug-in results in an
                environment that has extensions specifically designed to let
                you more easily develop software.
                These extensions allow for cross-compilation, deployment, and
                execution of your output into a QEMU emulation session as well
                as actual target hardware.
                You can also perform cross-debugging and profiling.
                The environment also supports performance enhancing
                <ulink url='http://www.eclipse.org/linuxtools/'>tools</ulink>
                that allow you to perform remote profiling, tracing,
                collection of power data, collection of latency data, and
                collection of performance data.

                            Cross Compiler options enable Eclipse to use your

                            To configure these options, you must select
                            the type of toolchain, point to the toolchain,
                            specify the sysroot location, and select the target

                                            a stand-alone cross-toolchain.
                                            For example, suppose you are an
                                            application developer and do not
                                            need to build a target image.
                                            Instead, you just want to use an
                                            architecture-specific toolchain on

                                            In other words, you have downloaded
                                            and installed a pre-built toolchain
                                            for an existing image.

                    You can create two types of projects:  Autotools-based, or
                    Makefile-based.
                    This section describes how to create Autotools-based
                    projects from within the Eclipse IDE.
                    For information on creating Makefile-based projects in a
                    terminal window, see the
                    "<link linkend='makefile-based-projects'>Makefile-Based Projects</link>"

                        Do not use special characters in project names
                        (e.g. spaces, underscores, etc.).  Doing so can
                        cause configuration to fail.

                        When building "Yocto Project SDK Autotools" projects,
                        the Eclipse IDE might display error messages for
                        Functions/Symbols/Types that cannot be "resolved",
                        even when the related include file is listed at the
                        project navigator and when the project is able to
                        build.
                        For these cases only, it is recommended to add a new

                                The host on which you are running QEMU must
                                have the <filename>rpcbind</filename> utility
                                running to be able to make RPC calls on a
                                server on that machine.
                                If QEMU does not invoke and you receive error
                                messages involving
                                <filename>rpcbind</filename>, follow the
                                suggestions to get the service running.
                                As an example, on a new Ubuntu 16.04 LTS
                                installation, you must do the following in
                                order to get QEMU to launch:
                                <literallayout class='monospaced'>
     $ sudo apt-get install rpcbind
                                </literallayout>
                                After installing <filename>rpcbind</filename>,
                                you need to edit the
                                <filename>/etc/init.d/rpcbind</filename> file
                                to include the following line:
                                <literallayout class='monospaced'>
     OPTIONS="-i -w"
                                </literallayout>
                                After modifying the file, you need to start the
                                service:
                                <literallayout class='monospaced'>
     $ sudo service portmap restart
                                </literallayout>

                            Once QEMU launches, you can begin operating
                            within that environment.
                            One useful task at this point would be to determine
                            the IP Address for the user-space NFS by using the
                            <filename>ifconfig</filename> command.
                            The IP address of the QEMU machine appears in the
                            xterm window.
                            You can use this address to help you see which
                            particular
                            IP address the instance of QEMU is using.

                <para>
                    Once the QEMU emulator is running the image, you can deploy
                    your application using the Eclipse IDE and then use
                    the emulator to perform debugging.
                    Follow these steps to deploy the application.
                    <note>
                        Currently, Eclipse does not support SSH port
                        forwarding.
                        Consequently, if you need to run or debug a remote
                        application using the host display, you must create a
                        tunneling connection from outside Eclipse and keep
                        that connection alive during your work.
                        For example, in a new terminal, run the following:
                        <literallayout class='monospaced'>
     $ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable>
                        </literallayout>
                        Using the above form, here is an example:
                        <literallayout class='monospaced'>
     $ ssh -XY root@192.168.7.2
                        </literallayout>
                        After running the command, add the command to be
                        executed in Eclipse's run configuration before the
                        application as follows:
                        <literallayout class='monospaced'>
     export DISPLAY=:10.0
                        </literallayout>
                        Be sure to not destroy the connection during your QEMU
                        session (i.e. do not
                        exit out of or close that shell).

                            However, if a previous QEMU session did not exit

                            location, QEMU will not understand what to remotely
                            launch.
                            Eclipse is helpful in that it auto fills your
