[dpdk-dev] [PATCH 0/3] real "make install" rule

[dpdk-dev] [PATCH 0/3] real "make install" rule

[Thomas Monjalon]

The current "make install" rule don't install anything.
It builds one or more targets with different configurations.

These patches allow to install only files needed to build and run a DPDK appplication.
The old behaviour is kept for compatibility and the new behaviour is
a second stage triggered by setting the DESTDIR variable.

So, the command "make install T=x86_64-default-linuxapp-gcc O=aaa DESTDIR=bbb"
will build in aaa/x86_64-default-linuxapp-gcc/ and install in bbb/.

The install directory can then be used as RTE_SDK path to build an application.

  mk: allow to specify O= in install rule
  mk: in install rule, don't overwrite .config if it already exists
  mk: allow to specify DESTDIR in build rule

[dpdk-dev] [PATCH 1/3] mk: allow to specify O= in install rule

[Thomas Monjalon]

From: Olivier Matz <olivier.matz@6wind.com>

This variable $(O) can be used to specify a build directory
when doing an "install" procedure. The default is ".", which
means that targets will be built in the source dpdk.

This option is useful to compile outside of the source tree that may be
read-only.

From: Olivier Matz <olivier.matz@6wind.com>

This allows the user to prepare a configuration with make config
before using make install.

[dpdk-dev] [PATCH 3/3] mk: allow to specify DESTDIR in build rule

[Thomas Monjalon]

From: Olivier Matz <olivier.matz@6wind.com>

This will install the binary sdk (bin + modules + libs + headers + mk)
in the specified directory.
This directory can be used as RTE_SDK by external applications.
