Default properties.Set C++ compiler and build properties in Visual Studio | Microsoft Docs
Jul 17, · The MSVC compiler () recognizes certain environment variables, specifically LIB, LIBPATH, PATH, and INCLUDE. When you build with the IDE, the properties that are set in the VC++ Directories Property Page property page are used to set those environment variables. If LIB, LIBPATH, and INCLUDE values have already been set, for example by a Developer Command Prompt, they are . The directory is included both in VC++ Directories AND in Additional Include Directories, with a full, unambiguous path. What a buggy implementation! What a waste of my time! Jul 10, · The method you use to set the VC++ directories are deprecated in VS Instead, you need to right click the properties of the project and set the directories there. The 1st and 2nd reply of this thread have already provided good threads, you could follow them. You cannot do the setting if you do not open a project.
Vc++ directories.VC++ Directories?
VC++ Directories: Include Directories. this value is inherited from the INCLUDE Windows environment variable which is defined outside of Visual Studio. environment variables can be: global to the computer or have user level scope; The INCLUDE and LIB environment variables are created when the Microsoft Windows SDK is installed with Visual Studio. The directory is included both in VC++ Directories AND in Additional Include Directories, with a full, unambiguous path. What a buggy implementation! What a waste of my time!

I have been in this situation quite a few times where visual studio does not honor the Additional Include Directories when it comes to lib and header source files. I even put them to absolute paths, Visual Studio still complained that it could not find specific header files. Does anybody experience the same thing with projects, and if so, is there a solution to this problem?
EDIT: My apologies for not being able to explain fully. I know that the library and source files have different include directories. The project that I received had correct directory paths for the Additional Include Directories and Additional Library Directories but Visual Studio still failed to recognize them properly.
I can right click and open the header file within Visual Studio but when compiling it still complains it cannot find the required header files. I regularly make projects relying on a framework I myself programmed, so I am quite familiar with how to set up dependencies.
This is however the second time this seems to be happening. I don’t recall which 3rd party project I was trying to compile last time, but Visual Studio simply refused to believe that the Additional Include Directories paths is where it should look for the header files. I am not sure how to give the complete details of this particular library MyGUI but I can point you to the website where you can download it to try and see if it is able to find the header files that are included in the project if it doesn’t compile, that is fine, and it is probably because of additional dependencies, but it should at least be able to find files in the common folder, especially when I put absolute paths in Additional Include Directories.
This happened to me once. It turned out the inconsistency of the Debug vs Release builds. When I modified one build, the other build was being compiled.
Please set both builds with same include folders and see if it works. Good luck. I have found stumbled on the solution I think. It has something to do with the character limit imposed by the OS. Although the limit should be , for me it falls in the below , see this discussion and links to it. I learned quite some time ago not to try to compile projects under such long paths, but this time it completely slipped my mind as VS did not give me a warning at all and pointed me in the wrong direction.
I am not going to checkmark the answer however until someone confirms this. I have the same problem : Can’t find. From an answer of Additional include directory in Visual studio doesn’t work , I tried:. I had this issue too. Just like sam said – this string value containing path to your framework includes has to be the same for the Debug and Release configurations. So the best way is to choose “Configuration:All Configurations” and “Platform:All Platforms” from the two context checklists on the top of the project properties window before typing it in, or copying from windows explorer adress bar.
I’ve just spent some hours battling with failing include paths in the compiler, inconsistencies between the compiler and intellisense.
I had to explicitly set it to “inherit from from parent or project defaults” — there’s a checkbox near the lower-left corner of the dialog for editing the directory path. My hypothesis was that maybe the “Existing Item” procedure skipped a property initialization step that “New Item” would normally perform.
But I just tested that hypothesis by Adding another Existing and a New. Both of these files had their property set to inherit from the project, so I don’t have an explanation for why my problem file was not initially set to inherit. Can you elaborate on this? If I recall, there are at least two places in Visual Studio where you can configure this:.
If you’re adding the include directories per-project 1 , which I think you are, and then trying to include from another project, this will obviously not work. Try adding them at the per-installation level and see if it works. If by lib files you mean library.
It’s logical if you think about it. Linker options are all linking options, settings involved with linking up. Navigating from header to header went fine, but after toggling to the source file of a header let’s say foo. I got the following error:. After research I noticed that the system build path given in the error where not extended with the include paths of the project.
In other words: IntelliSense didn’t know that the source file foo. The fix for me was creating a file intelliSense. This file contains an include for each source file.
This way IntelliSense knows that these source files are part of the project, and will therefore use the include paths of the project to resolve the includes in those source files. For me the issue was that. I was surprised that VS did not complain about this file being read-only. For me it turned out that the active setting is also depending on the ‘solution configuration’ and ‘solution platform’. That makes 4 settings which all should be identical.
I realize this question is over 10 years old at this point, but I also just ran into this issue and none of the answers fit my scenario. After some playing with my IDE VS for a few minutes I realized that the cpp file I was using had it’s platform set to Win32, but the libs I was trying to use were built for x As others have stated, make sure your project’s configuration is set to -” All Configurations ” when you add the necessary paths to your project as that can also be an issue.
I imagine my issue will not be as common, but I figured it was worth sharing. I hope this helps someone else in the future. One more possible reason not mentioned earlier: make sure you are configuring properties of the correct project in a multi-project solution.
My problem was that I had a solution of two projects each using the same file with includes. Turns out that I correctly configured ‘Additional Include Directories’ only for one of two projects and totally forgot about another one.
Of course error message was stating that only the second project and not the first one had problems. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

I’ve been wasting hours trying to get Visual Studio to recognize a header file in another directory. It’s obviously there; I can right-click it in Solution Explorer and open it. But my include is red-underlined, and it says “cannot open source file”.
What a buggy implementation! What a waste of my time! It’s not feasible to alter dozens of header files to use full paths! Damn, I hate Microsoft! Finally came up with a workaround: Changed from x86 to x64 and the include statements started working. This is a violation of the laws of the language!! The word length should have no effect whatsoever on a correct program.
Words alone can’t express my disgust. Ok, my bad: The properties configuration was set to x64, but my program’s configuration was x86, so my changes weren’t seen. I still think it’s another gotcha that the properties configuration doesn’t default to the same configuration as the program.

That’s what worked for me in Visual Studio Merely changing the include directory in static lib project was not enough, I had to change the main project’s setting as well to make it work, even if I was only trying to build the static lib project. Does anyone know if VS imposes a limit on the length of these paths to ensure that, when invoking cl.

Actually, I would advise against adding random libraries to the whole environment. A cleaner solution is to just add the needed directories to both projects – you don’t really want each and every library lingering around in your environment.
It really depends on a number of factors. If you’re talking about say, adding Qt – then globally would be wise as chances are you’re using that in many projects on the same machine.
