Please refer to the answer in following thread. In addition, there has any other communities has the problem about using some toolchain in there project. I will create a sample projectĪnd try reproduce your problem in my side. In addition, please tell us what's toolchain you are use and the detailed steps that you operated. Please try set Include Search Path property as the path of the toolchain.Īnd in order to confirm whether it is related to the toolchain itself, please try change another toolchain using the same steps.
#Visual studio 2015 intellisense errors how to#
Please try with the steps in following article which introduce how to enable IntelliSense for Makefile Projects. In short, how can I fix the 1,245 IntelliSense errors when working with Makefile projects? Or what fixes should I need to do to get rid of these errors? Please let me know if I'm missing something else, or you need more updated info. They all use MinGW GCC to compile the code, so I don't know if this is relevant to IntelliSense throwing errors of all sorts around. Project Property Pages are not set correctly.įor references, here's the File Explorer directory when opening up the include folders listed above:įor this image shown below, I have no idea if I should put "/include/c++/5.3.0/" in or just use "/include/": Or maybe it is because my VC++ Directories in the I really am lost at this point, because I thought IntelliSense will be able to pick up GNU standard C and standard C++ header function prototypes, typical namespace declarations, and such. Has the error, "namespace std has no member string" when putting "#include " at the top of the main.cpp. I now have 1,245 IntelliSense errors, mostly because the GNU standard C and standard C++ headers use a different C syntax (My presumption, and may be incorrect.) that the toolchain itself allows, but not for IntelliSense. The reference to the root folder to parse header files with (using "/include/c++/5.3.0/" as the actual root include folder). They would put GNU standard C++ headers and associated header files inside "/path/to/toolchain/include/c++/5.3.0/" I don't know exactly why it needs to be placed as such, but I figured it should be the same as giving the Include Paths I did all the necessary setups it required for IntelliSense to read/parse the C include headers and C++ include headers, but I noticed the toolchain provides their own GNU C and GNU C++ standard headers, located in weird file paths. I would like to use Visual Studio and IntelliSense to help me out. This workaround is often required when those folders contain some old DLL file (for example, when you change the Assembly Name of one or more projects): when this happens, the Build -> Clean command might be unable to automatically sort things out, since it will only clean up the known project files.I have a Makefile project with its own unique toolchain that it uses to compile C and C++ codes to something a device can read.

It's worth noting that the /.vs/ root folder only exists since Visual Studio 2015: if you're using Visual Studio 2013 or below, you can achieve the same results by directly deleting the.

The first thing to try when this issue hits your project is to entirely remove the /.vs/ folder, which is the directory where Visual Studio stores some user-related configuration files and temporary data: deleting that folder is safe, since VS will automatically recreate it when it opens the solution (if it doesn't exist). Luckily enough, there are a couple workaround that can hopefully fix this nasty issue. These errors are usually related to "missing" classes or namespaces, that do actually exist (and often even compile properly).

If you've stumbled upon this post it most likely means that you're struggling with a strange issue with Visual Studio Intellisense: it seems to work fine for existing files, but it show non-existing "errors" (in the Error Window and through the "red wavy underlines" inside the file) when you either create a new source code file or copy/paste an existing one.
