If you experience an error of "netmon.h: No such file or directory" while compiling WpcapSrc, it may mean that your build environment is missing the file. Typically, this file is located in the Include directory of the Windows SDK.
You can try the following to solve this problem:
1. Install the Windows SDK: If you have not installed the Windows SDK, you can download and install the Windows SDK from the Microsoft Download Center. After installation, "netmon.h" should be located in the "C:\Program Files(x86)\Windows Kits\10\Include\10.0.xxx.x\um" directory, where "xxx" is the Windows SDK version number.
2. Update the Windows SDK: If you have installed the Windows SDK but cannot find the "netmon.h" file, please try to update the Windows SDK version. After updating the Windows SDK, recompiling WpcapSrc should find the "netmon.h" file.
Set compilation environment variables: If you have installed the Windows SDK and the compiler still cannot find the "netmon.h" file, check that the compiler has correctly set the Include directory for the Windows SDK. You can add the Windows SDK's Include directory to the compiler's Include path, or use an environment variable to add the directory to the Include path.
