Realtime compilation fails

Development Programming & Scripting
1

Hi I have problem with realtime compilation, I use compile button in editor. I can successfully compile engine from source code, I can successfully compile my project, but every attempt of realtime compilation within editor fails.

Also during compilation there comes popup saying: MSVCP120.dll is missing from your computer.
I have visual studio 2013 installed and even tried to manually install Visual Studio 2013 redistributables. None of this works for me.

I do not change header files and i do not add any additional functions. I just comment one line and click on compile, still does not works for me :frowning:

I offer my eternal gratitude for any advice :wink:

I am using Windows7 64x

This is what compile log says:

Info rc.exe TestProject.rc
Error D:\dev\workspace\UnrealProjects\TestProject\Source\TestProject\Resources\Windows\TestProject.rc(11)  : fatal error RC1015: cannot open include file 'windows.h'.

You can’t build your project via Visual Studio while it’s loaded in engine, either close editor and build it, or click Compile in editor. But there’s a huge limitation in current hot-reload functionality, you would need to close editor if you’ve changed something in header files. For more information about it check forums, it was discussed somewhere, can’t give link, sorry.

Hm, strange, it works fine for me. Though i can’t open project VS solution via editor while others can, seems like everybody experiencing various problems :slight_smile:

Thanks for answer, i am using compile button in editor, i do not change header files, do not add any new functions as i come across similar problem, where this malfunction was caused by changing header file or adding additional functions, but even when i just comment one line in already existing function it fails. I hope realtime compilation is possible cause it will be much more easier to tweak code and values using it :slight_smile:
