Editor Compile No Longer Works, Only Compiling from VS Does

As of 4.10 preview 3, I can not longer compile from editor. I get this error:

CompilerResultsLog: Info C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE\typeinfo(21): fatal error C1083: Cannot open include file: ‘string.h’: No such file or directory

I can compile fine from VS 2015, so I can work. But clearly, there is some difference as to paths or something between the two modes.

Hey -

I was able to add a new class and add code to the class which compiled when using the in-editor compile button. Do you get the same error inside a newly created 4.10 project? Also, does your computer have VS 2013 as well or are you only using VS2015?

Cheers

I have both VS 2013 as well as VS2015 installed. And there is 4.9.2 on there as well as 4.10. I should add some other details:

  1. this is a project ported from 4.9.2 to 4.10 (from prev1-3)

  2. it is not uncommon for me to encounter this kind of header error the Unreal, particularly on new or newly ported projects…but normally one finds that the “VC++ Directories” of the project are empty for some reason, and you just need to “inherit from project defaults” to get these going. But that wasn’t the case here.

  3. Note that I have a customized .builld.cs file, where I do bring in a number of outside headers and libraries. Of, course I would expect that build file to be run regardless of whether I am compiling from VS or Unreal.

  4. have not tried a newly created project, but will go back the the machine and try that and post results in a couple hours.

I’ve still not been able to reproduce the error message you mentioned. Can you let me know if you get the same error in a new 4.10 project or in a new 4.9 project that is converted to 4.10? Also, does the error continue in 4.10 Preview 4?
