DPDK-20.11. Version 3 uses meson and ninja for compilation and installation. Refer to the previous process DPDK-20.11.3 in CentOS 8 Compile and run on 4 According to this step, after the compilation and installation is completed, it can be found that the test case executable has been generated in the build/app and build/example directories.
At this time, you can start and execute the startup command according to each use case.
But what if you want to add some print information to the test case? The following is a brief introduction to how to compile dpdk test cases separately.
Explain in advance:
1. The DPDK version number is 20.11 3. The operating system is CentOS 8.4;
2. Because meson and ninja tools are not familiar, test cases are compiled through Makefile;
3. There are many test cases for DPDK, which cannot be enumerated one by one, so use l3fwd cases for description;
4. Makefile files that can be compiled directly already exist under the test case, but the compilation depends on the DPDK installation environment. The following needs to be done is to compile without relying on the DPDK installation environment. (that is, put the static library, dynamic library, header file and *. c file required for compilation into one file, so that even if the modified file is moved to other operating systems without DPDK installed, it can be compiled and executed. In the actual application process, that is, just put the static library and header file dependent in the project under the specified path, which can be used by calling relevant API s).
Brief steps:
1. Create the project directory dpdk-l3fwd, and add the required static library, dynamic library, header file, * c) copy the document to the document;
2. Modify the Makefile file, mainly setting the environment variables and link library path required for compilation;
3. Compilation (static compilation and dynamic compilation);
4. Summary.
1. Create project
1.1. Create dpdk-l3fwd directory
Create dpdk-l3fw project directory, subdirectory and related files as follows.
[root@LFTF dpdk-l3fwd]# ll total 36 drwxr-xr-x. 2 root root 128 Dec 29 13:15 app drwxr-xr-x. 2 root root 6 Dec 29 10:39 include drwxr-xr-x. 2 root root 6 Dec 29 10:39 lib -rw-r--r--. 1 root root 0 Dec 29 13:23 Makefile drwxr-xr-x. 2 root root 6 Dec 29 13:23 pkgconfig
among
app is a code subdirectory, which is used to store other than main c others c) documents;
include is the header file directory, which is used to store dpdk related header files and app directories c) dependent header file;
lib is the library file directory, which is used to store the static library files compiled by the dpdk source agent;
Makefile, example: the makefile file included in the example needs to be modified;
There are two in the pkgconfig file pc file, which is used to maintain the path linking dpdk static library and dynamic library; (detailed later);
1.2 source and library files
1.2. 1. Copy static / dynamic libraries and related header files
DPDK-20.11.3 after the compilation and installation is completed, the relevant static library and dynamic library files will be generated to the Linux system directory / usr/local/lib64 /, which can be viewed by using the following ll command. The dpdk related header files are in the path of usr/local/include:

Create a dpdk file in the dpdk-l3fwd/lib directory and copy the static library and dynamic library of dpdk under the path / usr/local/lib64 /
[root@LFTF lib]# mkdir dpdk [root@LFTF lib]# [root@LFTF lib]# ll total 0 drwxr-xr-x. 2 root root 6 Dec 29 13:47 dpdk
Copy static library
[root@LFTF lib]# cp /usr/local/lib64/*rte*.a /home/dpdk-l3fwd/lib/dpdk/ [root@LFTF lib]#
Copy dynamic library
[root@localhost ~]# cp /mnt/hgfs/code/dpdk/dpdk-l3fwd/lib/dpdk/*.so* /home/dpdk-l3fwd/lib/dpdk [root@localhost ~]#
If only static libraries or dynamic libraries are required, operate on demand.
Create a dpdk file in the dpdk-l3fwd/include directory and copy the header file about dpdk in the path of / usr/local/include /
[root@LFTF include]# pwd /home/dpdk-l3fwd/include [root@LFTF include]# [root@LFTF include]# mkdir dpdk [root@LFTF include]# ll total 0 drwxr-xr-x. 2 root root 6 Dec 29 17:24 dpdk

1.2. 2. Copy pkgconfig file
The principle and usage of PKG config can be searched by yourself or referred to Principle and usage of PKG config；
Only dpdk related is explained here The storage path of pc files is / usr/local/lib64/pkgconfi
[root@localhost ~]# ll /usr/local/lib64/pkgconfig/ total 8 -rw-r--r--. 1 root root 1055 Dec 25 11:52 libdpdk-libs.pc -rw-r--r--. 1 root root 4082 Dec 25 11:52 libdpdk.pc
Copy the two files in this directory to dpdk-l3fwd/pkgconfig
[root@localhost ~]# cp -r /usr/local/lib64/pkgconfig/ /home/dpdk-l3fwd/pkgconfig/ [root@localhost ~]#
When the Makefile is executed later, it depends on the data in this path pc content, so it needs to be changed pc path

In short, we used to rely on the dynamic library and static library path installed in the system directory of dpdk, but now we have to rely on the static library and dynamic library path under the current project.
1.2. 3. Copy l3fwd source code
Dpdk-20.11 3. Copy the source code under the source code example/l3fwd path to the specified path.

2.3 comparison before and after
There are three modifications:
1. Need to compile c file has project path and wildcard to obtain, which is more flexible and convenient;
2. The environment variable when PKG config is executed is the path where the current project is located, so the link between static library and dynamic library depends on the path under PKG config in the current project pc files;
3. The previous Makefile was not generated o intermediate files have also been added.
3. Compile
By modifying the statements in Makefile, you can control whether to link static libraries or dynamic libraries
