	I have an existing non-Arduino project with the following folder structure: Top Level -> SharedCode -> SharedCode2 -> PortForMicrocontrollerXXX -> PortForMicrocontrollerYYY -> PortForArduino I am working in the 'PortForArduino' folder so this is where my VS2017 project file is. I need to include in the compile the shared code in the tree. Because this is an existing project I can't make copies of the shared code or move it. I don't care about compatibility with the Arduino IDE. If I understand it right I can't create an Arduino library because I would have to put Arduino-specific files into the top level folder, which I can't do because no code resides there and it would break the folder hierarchy. In the VM project properties under Extra Flags I have added: Code -I . -I ../SharedCode -I ../SharedCode2 I understand this does not compile the code - fine. I have added the shared code source files to the VS project. In this post: http://www.visualmicro.com/forums/YaBB.pl?num=1455641592/16#16 and this one: http://www.visualmicro.com/forums/YaBB.pl?num=1455641592/14#14 you mention using shortcuts to bring in external code that is outside of the VS2017 project folder. In VS2017 I right-click on my project, choose Add -> Existing Item... and choose a file but the Add button in the dialog does not have the drop-down option to add as a link. Seems that is only available for managed projects, e.g. .NET. In one of the posts I referenced above you said: Quote: right click folder>add existing>link Where is this - in Windows Explorer? VS2017? The compilation error I get is: Code Fatal error: foo.h: No such file or directory foo.h is located in PortForArduino. It is included in a .c file in SharedCode. Do you have any hints or suggestions for achieving what I want to do while respecting and maintaining my existing folder structure? Thanks!

	OK, made some progress. It seems my relative paths were not working. If I use: Code -I "C:\foo\bar\baz\PortForArduino" -I "C:\foo\bar\baz\SharedCode" -I "C:\foo\bar\baz\SharedCode2" it compiles my external files and finds the header files. Is there an equivalent in VM to VS's $(ProjectDir)?

	After much searching I worked it out. I needed: Code -I "{build.project_path}" -I "{build.project_path}\..\SharedCode" -I "{build.project_path}\..\SharedCode2"

	Sorry for the delayed response. Yes that will work as long as there are no code files to be compiled. Just headers. An alternative is to use visual studio shared projects. You can get the idea of how they work using the "add Library" menu which has a checkbox that "always creates project when adding libraries". Check the menu item then add spi, for example. You will see that visual studio shared projects are simply a project_name.vcxitems file that appears as a special type of project in the solution tree. You can then right click "References" on one of the real arduino projects and then on the "shared projects" tab add the reference. Only real projects can be "Start up Projects" which can be selected by right clicking a project in the solution tree. When editing shared project code Visual studio will automatically show intellisense based on the current startup project. So you can edit shared code for different platforms more easily. A compiler -I include path is automatically added for each shared project root path (which is where the .vcxitems is located. Shared code must exist in or below the root folder. The top of the visual micro home page contains a few useful links such as cross-platform shared code and library development note there is a shared code project entry in the File>New>Project list
