2. Compiling the Application

The testpmd application is compiled as part of the main compilation of the DPDK libraries and tools. Refer to the DPDK Getting Started Guides for details. The basic compilation steps are:

1. Set the required environmental variables and go to the source directory:

   export RTE_SDK=/path/to/rte_sdk
   cd $RTE_SDK
   

2. Set the compilation target. For example:

   export RTE_TARGET=x86_64-native-linux-gcc
   

3. Build the application:

   make install T=$RTE_TARGET
   

   The compiled application will be located at:

   $RTE_SDK/$RTE_TARGET/app/testpmd
