This section explains how to compile the DPDK 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
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 $RTE_SDK/examples/.
Build the application:
export RTE_TARGET=build make
For cross compiling the sample application(s), please append ‘CROSS=$(CROSS_COMPILER_PREFIX)’ to the ‘make’ command. In example of AARCH64 cross compiling:
export RTE_TARGET=build export RTE_SDK=/path/to/rte_sdk make -C examples CROSS=aarch64-linux-gnu- or make CROSS=aarch64-linux-gnu-
