2. Compiling the Sample Applications

2.1. To compile all the sample applications

Set the path to DPDK source code if its not set:

export RTE_SDK=/path/to/rte_sdk

Go to DPDK source:

cd $RTE_SDK

Build DPDK:

make defconfig
make

Build the sample applications:

export RTE_TARGET=build
make -C examples

For other possible RTE_TARGET values and additional information on compiling see Compiling DPDK on Linux or Compiling DPDK on FreeBSD. Applications are output to: $RTE_SDK/examples/app-dir/build or $RTE_SDK/examples/app-dir/$RTE_TARGET.

In the example above the compiled application is written to the build subdirectory. To have the applications written to a different location, the O=/path/to/build/directory option may be specified in the make command.

make O=/tmp

To build the applications for debugging use the DEBUG option. This option adds some extra flags, disables compiler optimizations and sets verbose output.

make DEBUG=1

2.2. To compile a single application

Set the path to DPDK source code:

export RTE_SDK=/path/to/rte_sdk

Go to DPDK source:

cd $RTE_SDK

Build DPDK:

make defconfig
make

Go to the sample application directory. Unless otherwise specified the sample applications are located in $RTE_SDK/examples/.

Build the application:

export RTE_TARGET=build
make
