IntelliSense: cannot open source file "curl.h" in C++

Question

I am unable to compile my C++ project.

IntelliSense: cannot open source file "curl.h" in C++

I tried adding that file to the "Header Files" folder in Solution Explorer: no change. I was unable to add it to the "Source Files" folder.

How can I fix this?

How are you including it in your source files/headers? – Oct 02 '11 at 01:20 — , Oct 02 '11 at 01:20

This, in most cases will fix intellisense errors for all header files – Jason Newland Jun 30 '13 at 20:35

How do you add the "$(ProjectDir)" into the "Reference Directories". It wont let me enter anything into the textbox. – stackexchange12 Feb 04 '14 at 22:35
@stackexchange12, it should let you, you can also go to the drop down and modify from there – tatigo Mar 12 '14 at 15:18

If you've added the header file correctly, then sometimes intellisense can be corrupted and you will need to delete the .ncb file in you project. Once this is done, restart VS and see if this works. The .ncb file is the intellisense database file so if you delete this, VS will rebuild it.

Thank you, but that did not work. Once I did that I had the same error, just not with intellisense. BTW, I right clicked and pressed "go to file or whatever" and then it brought me to the file! So it knows the file is there, it just can't find it for some reason D:< Any other ideas why it didn't work? – user975017 Oct 02 '11 at 02:23

Did you include it as #include<"myfile.h"> or #include "myfile.h" because you are not supposed to put "<>" when including your own header files. Use the "<>" to include c++ standard header files. So in your case, put #include "myfile.h" – roboto1986 Oct 02 '11 at 16:52
