I am converting from Eclipse CDT. The preprocessor macro feature is a must when navigating through C/C++ code with preprocessor defines (whether explicitly specified in Makefile or included through an external auto-generated header file). Without this, navigating the Linux source would be impossible, as described on this seminal wiki page on using Eclipse to study the Linux code. I am looking for an equivalent feature for VSC. Would appreciate a pointer.

w/ regards

  1. Install ms-vscode.cpptools extension.
  2. Open kernel source folder in VSCode.
  3. Follow the instructions, add "${workspaceFolder}/include" and "${workspaceFolder}/arch/{your arch}/include" to includePath, "your arch" is x86/arm etc.
  4. Wait for IntelliSence indexing.

In the Project type: pane, click the Makefile project and select Empty Project; On the right side, select Linux GCC. Click Next; Click Advanced settings and a Properties dialog will pop up.

I did't need to add the arch folder (for x86_64 it was actually empty), but add some basic defines to make compiler specific types and macros visible to intellisense. My minimal config is shown below. For perfect results you would have to add all defines as configured in your kernel .config file (e.g. CONFIG_MMU). There are many of those, so typically you will only focus on the few you really care about.

Visual Studio Code for Linux kernel development, First things first for me is getting a vim mode going, and Code has a pretty good one of those. The first thing I did was check out the vscode-linux-kernel project by Ctrl-P lets you quickly navigate to any file with fuzzy-matching (which It has shortcomings, but installing Code and using the repo above to  Talk:HowTo use the CDT to navigate Linux kernel source I downloaded and installed the latest (Luna) eclipse and followed the steps. The only problem I had is a wrong parsing/indexing of container_of macro.

As of today I have found the use of the vscode-linux-kernel project to be superior to both answers listed above, as navigation through the code and Intellisense works very well.

The project is released to the public domain.

  • I'm working with kernel and this answer worked like a charm. I notice that if you are working with modules development you can also use your machine's linux headers. In my case, added to settings.json : ` C_Cpp.default.includePath": ["/usr/src/linux-headers-5.0.0-custom-buster/arch/x86/include/" , "/usr/src/linux-headers-5.0.0-custom-buster/include/"] `
  • you would have to add all defines as configured in your kernel .config file All defines are already in include/generated/autoconf.h (under /usr/src/linux-headers-$(uname -r)/), should be enough to forceInclude it in c_cpp_properties.json.
