There are some references to DPDK.xyz.mk files that do not exist in the dpdk tree. This was probably the result of an automatic replacement, so restore the proper file names which are rte.xyz.mk. Signed-off-by: Olivier Matz <olivier.matz@6wind.com>

External Application/Library Makefile help
|
|
==========================================
|
|
|
|
External applications or libraries should include specific Makefiles from RTE_SDK, located in mk directory.
|
|
These Makefiles are:
|
|
|
|
* ${RTE_SDK}/mk/rte.extapp.mk: Build an application
|
|
|
|
* ${RTE_SDK}/mk/rte.extlib.mk: Build a static library
|
|
|
|
* ${RTE_SDK}/mk/rte.extobj.mk: Build objects (.o)
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
The following variables must be defined:
|
|
|
|
* ${RTE_SDK}: Points to the root directory of the DPDK.
|
|
|
|
* ${RTE_TARGET}: Reference the target to be used for compilation (for example, x86_64-native-linuxapp-gcc).
|
|
|
|
Build Targets
|
|
-------------
|
|
|
|
Build targets support the specification of the name of the output directory, using O=mybuilddir.
|
|
This is optional; the default output directory is build.
|
|
|
|
* all, "nothing" (meaning just make)
|
|
|
|
Build the application or the library in the specified output directory.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
make O=mybuild
|
|
|
|
* clean
|
|
|
|
Clean all objects created using make build.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
make clean O=mybuild
|
|
|
|
Help Targets
|
|
------------
|
|
|
|
* help
|
|
|
|
Show this help.
|
|
|
|
Other Useful Command-line Variables
|
|
-----------------------------------
|
|
|
|
The following variables can be specified at the command line:
|
|
|
|
* S=
|
|
|
|
Specify the directory in which the sources are located. By default, it is the current directory.
|
|
|
|
* M=
|
|
|
|
Specify the Makefile to call once the output directory is created. By default, it uses $(S)/Makefile.
|
|
|
|
* V=
|
|
|
|
Enable verbose build (show full compilation command line and some intermediate commands).
|
|
|
|
* D=
|
|
|
|
Enable dependency debugging. This provides some useful information about why a target must be rebuilt or not.
|
|
|
|
* EXTRA_CFLAGS=, EXTRA_LDFLAGS=, EXTRA_ASFLAGS=, EXTRA_CPPFLAGS=
|
|
|
|
Append specific compilation, link or asm flags.
|
|
|
|
* CROSS=
|
|
|
|
Specify a cross-toolchain header that will prefix all gcc/binutils applications. This only works when using gcc.
|
|
|
|
Make from Another Directory
|
|
---------------------------
|
|
|
|
It is possible to run the Makefile from another directory, by specifying the output and the source dir. For example:
|
|
|
|
.. code-block:: console
|
|
|
|
export RTE_SDK=/path/to/DPDK
|
|
export RTE_TARGET=x86_64-native-linuxapp-icc
|
|
make -f /path/to/my_app/Makefile S=/path/to/my_app O=/path/to/build_dir
|
