+********************************
+Using the SDK Toolchain Directly
+********************************
+
+You can use the SDK toolchain directly with Makefile and Autotools-based
+projects.
+
+Autotools-Based Projects
+========================
+
+Once you have a suitable :ref:`sdk-manual/sdk-intro:the cross-development toolchain`
+installed, it is very easy to develop a project using the `GNU
+Autotools-based <https://en.wikipedia.org/wiki/GNU_Build_System>`__
+workflow, which is outside of the :term:`OpenEmbedded Build System`.
+
+The following figure presents a simple Autotools workflow.
+
+.. image:: figures/sdk-autotools-flow.png
+ :align: center
+
+Follow these steps to create a simple Autotools-based "Hello World"
+project:
+
+.. note::
+
+ For more information on the GNU Autotools workflow, see the same
+ example on the
+ GNOME Developer
+ site.
+
+1. *Create a Working Directory and Populate It:* Create a clean
+ directory for your project and then make that directory your working
+ location.
+ ::
+
+ $ mkdir $HOME/helloworld
+ $ cd $HOME/helloworld
+
+ After setting up the directory, populate it with files needed for the flow.
+ You need a project source file, a file to help with configuration,
+ and a file to help create the Makefile, and a README file:
+ ``hello.c``, ``configure.ac``, ``Makefile.am``, and ``README``,
+ respectively.
+
+ Use the following command to create an empty README file, which is
+ required by GNU Coding Standards:
+ ::
+
+ $ touch README
+
+ Create the remaining
+ three files as follows:
+
+ - ``hello.c``:
+ ::
+
+ #include <stdio.h>
+
+ main()
+ {
+ printf("Hello World!\n");
+ }
+
+ - ``configure.ac``:
+ ::
+
+ AC_INIT(hello,0.1)
+ AM_INIT_AUTOMAKE([foreign])
+ AC_PROG_CC
+ AC_CONFIG_FILES(Makefile)
+ AC_OUTPUT
+
+ - ``Makefile.am``:
+ ::
+
+ bin_PROGRAMS = hello
+ hello_SOURCES = hello.c
+
+2. *Source the Cross-Toolchain Environment Setup File:* 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". For this example, the
+ command sources a script from the default SDK installation directory
+ that uses the 32-bit Intel x86 Architecture and the 3.1.2 Yocto
+ Project release:
+ ::
+
+ $ source /opt/poky/3.1.2/environment-setup-i586-poky-linux
+
+3. *Create the configure Script:* Use the ``autoreconf`` command to
+ generate the ``configure`` script.
+ ::
+
+ $ autoreconf
+
+ The ``autoreconf``
+ tool takes care of running the other Autotools such as ``aclocal``,
+ ``autoconf``, and ``automake``.
+
+ .. note::
+
+ If you get errors from
+ configure.ac
+ , which
+ autoreconf
+ runs, that indicate missing files, you can use the "-i" option,
+ which ensures missing auxiliary files are copied to the build
+ host.
+
+4. *Cross-Compile the Project:* This command compiles the project using
+ the cross-compiler. The
+ :term:`CONFIGURE_FLAGS`
+ environment variable provides the minimal arguments for GNU
+ configure:
+ ::
+
+ $ ./configure ${CONFIGURE_FLAGS}
+
+ For an Autotools-based
+ project, you can use the cross-toolchain by just passing the
+ appropriate host option to ``configure.sh``. 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
+ ``armv5te-poky-linux-gnueabi``. You will notice that the name of the
+ script is ``environment-setup-armv5te-poky-linux-gnueabi``. Thus, the
+ following command works to update your project and rebuild it using
+ the appropriate cross-toolchain tools:
+ ::
+
+ $ ./configure --host=armv5te-poky-linux-gnueabi --with-libtool-sysroot=sysroot_dir
+
+5. *Make and Install the Project:* These two commands generate and
+ install the project into the destination directory:
+ ::
+
+ $ make
+ $ make install DESTDIR=./tmp
+
+ .. note::
+
+ To learn about environment variables established when you run the
+ cross-toolchain environment setup script and how they are used or
+ overridden when the Makefile, see the "
+ Makefile-Based Projects
+ " section.
+
+ This next command is a simple way to verify the installation of your
+ project. Running the command prints the architecture on which the
+ binary file can run. This architecture should be the same
+ architecture that the installed cross-toolchain supports.
+ ::
+
+ $ file ./tmp/usr/local/bin/hello
+
+6. *Execute Your Project:* To execute the project, you would need to run
+ it on your target hardware. If your target hardware happens to be
+ your build host, you could run the project as follows:
+ ::
+
+ $ ./tmp/usr/local/bin/hello
+
+ As expected, the project displays the "Hello World!" message.
+
+Makefile-Based Projects
+=======================
+
+Simple Makefile-based projects use and interact with the cross-toolchain
+environment variables established when you run the cross-toolchain
+environment setup script. The environment variables are subject to
+general ``make`` rules.
+
+This section presents a simple Makefile development flow and provides an
+example that lets you see how you can use cross-toolchain environment
+variables and Makefile variables during development.
+
+.. image:: figures/sdk-makefile-flow.png
+ :align: center
+
+The main point of this section is to explain the following three cases
+regarding variable behavior:
+
+- *Case 1 - No Variables Set in the Makefile Map to Equivalent
+ Environment Variables Set in the SDK Setup Script:* Because matching
+ variables are not specifically set in the ``Makefile``, the variables
+ retain their values based on the environment setup script.
+
+- *Case 2 - Variables Are Set in the Makefile that Map to Equivalent
+ Environment Variables from the SDK Setup Script:* Specifically
+ setting matching variables in the ``Makefile`` during the build
+ results in the environment settings of the variables being
+ overwritten. In this case, the variables you set in the ``Makefile``
+ are used.
+
+- *Case 3 - Variables Are Set Using the Command Line that Map to
+ Equivalent Environment Variables from the SDK Setup Script:*
+ Executing the ``Makefile`` from the command line results in the
+ environment variables being overwritten. In this case, the
+ command-line content is used.
+
+.. note::
+
+ Regardless of how you set your variables, if you use the "-e" option
+ with
+ make
+ , the variables from the SDK setup script take precedence:
+ ::
+
+ $ make -e target
+
+
+The remainder of this section presents a simple Makefile example that
+demonstrates these variable behaviors.
+
+In a new shell environment variables are not established for the SDK
+until you run the setup script. For example, the following commands show
+a null value for the compiler variable (i.e.
+:term:`CC`).
+::
+
+ $ echo ${CC}
+
+ $
+
+Running the
+SDK setup script for a 64-bit build host and an i586-tuned target
+architecture for a ``core-image-sato`` image using the current 3.1.2
+Yocto Project release and then echoing that variable shows the value
+established through the script:
+::
+
+ $ source /opt/poky/3.1.2/environment-setup-i586-poky-linux
+ $ echo ${CC}
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/3.1.2/sysroots/i586-poky-linux
+
+To illustrate variable use, work through this simple "Hello World!"
+example:
+
+1. *Create a Working Directory and Populate It:* Create a clean
+ directory for your project and then make that directory your working
+ location.
+ ::
+
+ $ mkdir $HOME/helloworld
+ $ cd $HOME/helloworld
+
+ After
+ setting up the directory, populate it with files needed for the flow.
+ You need a ``main.c`` file from which you call your function, a
+ ``module.h`` file to contain headers, and a ``module.c`` that defines
+ your function.
+
+ Create the three files as follows:
+
+ - ``main.c``:
+ ::
+
+ #include "module.h"
+ void sample_func();
+ int main()
+ {
+ sample_func();
+ return 0;
+ }
+
+ - ``module.h``:
+ ::
+
+ #include <stdio.h>
+ void sample_func();
+
+ - ``module.c``:
+ ::
+
+ #include "module.h"
+ void sample_func()
+ {
+ printf("Hello World!");
+ printf("\n");
+ }
+
+2. *Source the Cross-Toolchain Environment Setup File:* 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". For this example, the
+ command sources a script from the default SDK installation directory
+ that uses the 32-bit Intel x86 Architecture and the DISTRO_NAME Yocto
+ Project release:
+ ::
+
+ $ source /opt/poky/DISTRO/environment-setup-i586-poky-linux
+
+3. *Create the Makefile:* For this example, the Makefile contains
+ two lines that can be used to set the ``CC`` variable. One line is
+ identical to the value that is set when you run the SDK environment
+ setup script, and the other line sets ``CC`` to "gcc", the default
+ GNU compiler on the build host:
+ ::
+
+ # CC=i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux
+ # CC="gcc"
+ all: main.o module.o
+ ${CC} main.o module.o -o target_bin
+ main.o: main.c module.h
+ ${CC} -I . -c main.c
+ module.o: module.c
+ module.h ${CC} -I . -c module.c
+ clean:
+ rm -rf *.o
+ rm target_bin
+
+4. *Make the Project:* Use the ``make`` command to create the binary
+ output file. Because variables are commented out in the Makefile, the
+ value used for ``CC`` is the value set when the SDK environment setup
+ file was run:
+ ::
+
+ $ make
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c main.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c module.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux main.o module.o -o target_bin
+
+ From the results of the previous command, you can see that
+ the compiler used was the compiler established through the ``CC``
+ variable defined in the setup script.
+
+ You can override the ``CC`` environment variable with the same
+ variable as set from the Makefile by uncommenting the line in the
+ Makefile and running ``make`` again.
+ ::
+
+ $ make clean
+ rm -rf *.o
+ rm target_bin
+ #
+ # Edit the Makefile by uncommenting the line that sets CC to "gcc"
+ #
+ $ make
+ gcc -I . -c main.c
+ gcc -I . -c module.c
+ gcc main.o module.o -o target_bin
+
+ As shown in the previous example, the
+ cross-toolchain compiler is not used. Rather, the default compiler is
+ used.
+
+ This next case shows how to override a variable by providing the
+ variable as part of the command line. Go into the Makefile and
+ re-insert the comment character so that running ``make`` uses the
+ established SDK compiler. However, when you run ``make``, use a
+ command-line argument to set ``CC`` to "gcc":
+ ::
+
+ $ make clean
+ rm -rf *.o
+ rm target_bin
+ #
+ # Edit the Makefile to comment out the line setting CC to "gcc"
+ #
+ $ make
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c main.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c module.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux main.o module.o -o target_bin
+ $ make clean
+ rm -rf *.o
+ rm target_bin
+ $ make CC="gcc"
+ gcc -I . -c main.c
+ gcc -I . -c module.c
+ gcc main.o module.o -o target_bin
+
+ In the previous case, the command-line argument overrides the SDK
+ environment variable.
+
+ In this last case, edit Makefile again to use the "gcc" compiler but
+ then use the "-e" option on the ``make`` command line:
+ ::
+
+ $ make clean
+ rm -rf *.o
+ rm target_bin
+ #
+ # Edit the Makefile to use "gcc"
+ #
+ $ make
+ gcc -I . -c main.c
+ gcc -I . -c module.c
+ gcc main.o module.o -o target_bin
+ $ make clean
+ rm -rf *.o
+ rm target_bin
+ $ make -e
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c main.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux -I . -c module.c
+ i586-poky-linux-gcc -m32 -march=i586 --sysroot=/opt/poky/2.5/sysroots/i586-poky-linux main.o module.o -o target_bin
+
+ In the previous case, the "-e" option forces ``make`` to
+ use the SDK environment variables regardless of the values in the
+ Makefile.
+
+5. *Execute Your Project:* To execute the project (i.e. ``target_bin``),
+ use the following command:
+ ::
+
+ $ ./target_bin
+ Hello World!
+
+ .. note::
+
+ If you used the cross-toolchain compiler to build
+ target_bin
+ and your build host differs in architecture from that of the
+ target machine, you need to run your project on the target device.
+
+ As expected, the project displays the "Hello World!" message.
