Compiling DPDK Application Using CMake with Static Libraries

When developing applications that utilize the Data Plane Development Kit (DPDK), encountering issues while linking static libraries can be a common hurdle. A user reached out with specific difficulties in compiling a DPDK application using CMake, leading to the question: How can I successfully compile a DPDK application with the appropriate linking to static libraries?

In this guide, we'll explore the problem and provide a clear, step-by-step solution to ensure your DPDK application compiles correctly without any panic issues.

Understanding the Problem

The user provided a snippet of their CMakeLists.txt which was generating an error during compilation. The linking commands specified a sequence that led to the application panicking, particularly when trying to link certain DPDK driver libraries. This often indicates that the order of linking or the specifications used may not be compatible with the current DPDK version being utilized.

Solution Breakdown

To address the user's concerns and compile a DPDK application using CMake with static libraries, let’s break down the steps in the solution clearly:

Step 1: Check DPDK Version

First and foremost, ensure you know which version of DPDK you are using. There are known bugs in certain DPDK versions that can affect library linking. We’ll be assuming a version higher than 20.11 based on the user’s context.

Step 2: Update CMakeLists.txt

Find Package Requirement

You’ll want to ensure that you can find and use the DPDK libraries correctly via pkg-config. First, in the parent folder of your CMake project, add the following lines to your CMakeLists.txt:

Set Library and Include Directories

Next, in your source folder's CMakeLists.txt, append:

Additional Notes

Static Libraries: The pkg_check_modules command will ensure that you can access the static libraries and CFLAGS through LIBDPDK_STATIC_LDFLAGS and LIBDPDK_STATIC_CFLAGS. This allows you to efficiently compile using static options provided by the DPDK installation.

Communicating with pkg-config: The established commands above will ensure that your application can properly identify and link the required DPDK libraries.

Conclusion

By following the steps outlined above, you will be equipped with a robust configuration in your CMakeLists.txt to compile your DPDK application using static libraries without encountering panic issues. As always, ensure you validate your DPDK version and check for any specific bugs or issues that may affect your compilation process.

Happy coding, and may your DPDK applications run smoothly!
