Configure a Linux project
Linux support is available in Visual Studio 2017 and later.
You can configure a Linux project to target a physical Linux machine, a virtual machine, or the Windows Subsystem for Linux (WSL).
Visual Studio 2019 version 16.1:
When targeting WSL, you can avoid the copy operations that are necessary for building and IntelliSense when targeting remote Linux systems.
You can specify separate Linux targets for building and debugging.
To view configuration options, select the Project > Properties menu, or right click on the project in Solution Explorer and select Properties from the context menu. The General settings appear.
By default, an executable (.out) is built. To build a static or dynamic library, or to use an existing Makefile, use the Configuration Type setting.
For more information about the settings in the property pages, see Linux Project Property Page Reference.
To change settings pertaining to the remote Linux computer, configure the remote settings that appear under General.
To specify a remote target Linux computer, use the Remote Build Machine entry. This will allow you to select one of the connections created previously. To create a new entry, see the Connecting to Your Remote Linux Computer section.
Visual Studio 2019 version 16.1: To target Windows Subsystem for Linux, click the down arrow for Platform Toolset and choose WSL_1_0. The other remote options will disappear and the path to the default WSL shell will appear in their place:
If you have side-by-side WSL installations, you can specify a different path here. For more information about managing multiple distros, see Manage and configure Windows Subsystem for Linux.
You can specify a different target for debugging on the Configuration Properties > Debugging page.
The Remote Build Root Directory determines the root location of where the project is built on the remote Linux computer. This will default to ~/projects unless changed.
The Remote Build Project Directory is where this specific project will be built on the remote Linux computer. This will default to $(RemoteRootDir)/$(ProjectName), which will expand to a directory named after the current project, under the root directory set above.
To change the default C and C++ compilers, or the Linker and Archiver used to build the project, use the appropriate entries in the C/C++ > General section and the Linker > General section. You can specify a certain version of GCC or Clang, for example. For more information see C/C++ Properties (Linux C++) and Linker Properties (Linux C++).
Copy sources (remote systems only)
This section does not apply when targeting WSL.
When building on remote systems, the source files on your development PC are copied to the Linux computer and compiled there. By default, all sources in the Visual Studio project are copied to the locations set in the settings above. However, additional sources can also be added to the list, or copying sources can be turned off entirely, which is the default for a Makefile project.
Sources to copy determines which sources are copied to the remote computer. By default, the @(SourcesToCopyRemotely) defaults to all source code files in the project, but does not include any asset/resource files, such as images.
Copy sources can be turned on and off to enable and disable the copying of source files to the remote computer.
Additional sources to copy allows you to add additional source files which will be copied to the remote system. You can specify a semi-colon delimited list, or you can use the := syntax to specify a local and remote name to use:
Since all compilation is happening on a remote computer (or WSL), several additional Build Events have been added to the Build Events section in Project Properties. These are Remote Pre-Build Event, Remote Pre-Link Event, and Remote Post-Build Event, and will occur on the remote computer before or after the individual steps in the process.
IntelliSense for headers on remote systems
This section does not apply when targeting WSL.
When you add a new connection in Connection Manager, Visual Studio automatically detects the include directories for the compiler on the remote system. Visual Studio then zips up and copies those files to a directory on your local Windows machine. After that, whenever you use that connection in a Visual Studio or CMake project, the headers in those directories are used to provide IntelliSense.
This functionality depends on the Linux machine having zip installed. You can install zip by using this apt-get command:
sudo apt install zip
To manage your header cache, navigate to Tools > Options, Cross Platform > Connection Manager > Remote Headers IntelliSense Manager. To update the header cache after making changes on your Linux machine, select the remote connection and then select Update. Select Delete to remove the headers without deleting the connection itself. Select Explore to open the local directory in File Explorer. Treat this folder as read-only. To download headers for an existing connection that was created prior to Visual Studio 2017 version 15.3, select the connection and then select Download.
