Guide to use QtCreator for Unreal Engine 4!

anonymous_user_4cb3192d · July 8, 2014, 2:02am

Sweet. But how do I do that? If I try to compile in QtCreator it says it can’t open the UE4Editor DLL. If I press compile in the editor it doesn’t seem to make any changes.

EDIT: Well, the compile button is working now, not sure what went wrong before.

Hi guys,

thanks for describing this for QTCreator under Windows. I currently try this with QT Creator using MacOS and need some help with:

I just uncommented this from defines.pri
DEFINES += “UBT_COMPILED_PLATFORM=Win64”
DEFINES += “WIN32=1”
DEFINES += “_WIN32_WINNT=0x0600”
DEFINES += “WINVER=0x0600”
DEFINES += “PLATFORM_WINDOWS=1”

Is there is Mac Substitue for that?

3./ Create a file BUILD_DLL.bat and copy this into :
Code:
UnrealBuildTool.exe YourProjectEditor Win64 Development “%CD%\YourProject.uproject” -rocket

-> I need the Mac equivalent for this. I searched for UnrealBuildTool but i tseems to be for Windows only.
I would think that xcodebuild CLI tool will be employed, right?

If somebody knows about this on a mac:
START UE4Editor.exe “%CD%\YourProject.uproject” Your_Map?game=YourProject -game -ResX=1280 -ResY=720
EXIT

I guess that UE4Editor has to be on the PATH (/Users/Shared/UnrealEngine/4.3/Engine/Binaries/Mac)
You would speed up my research if the other Mac+QTCreator users would share their insights here or in that wiki article

thanks

Can we just run a find and replace on 4.3 to 4.4 to use this with 4.4? Or have any paths changed/been added?

I second the request for Qt Creator .pro file support in the Unreal Build Tool!

Antares · August 28, 2014, 11:16am

You have to open the visual file with visual and go to project propertie, this is where I found all include etc, I may update the post one of these day… But don’t have much time recently sorry !

I have to say hats off to Microsoft, respect guys. They listened to complaints about the way VS handles large solutions and there you go

Speedy, impressive!

KurtCobien · October 16, 2014, 8:48am

I tried to update the hard references to unreal version using a variable called UNREAL_VERSION = 4.5 but in fact it is not working at all. Qt Creator intellisesne does not work anymore.

eWomerOC · November 13, 2014, 9:16pm

Why is your INCLUDEPATH so short? trying to optimize the .pro file generator on linux and the list I parse is over, without cleaning it up a bit, 2500+ lines.

eWomerOC · November 14, 2014, 12:43am

Also why do you include some Engine/Intermediate/Build/Linux/x86_64-unknown-linux-gnu//Inc/ paths along with other not /Intermediate/ paths?

Saiboat · December 18, 2014, 1:39pm

Hello. I am also trying to get QtCreator to work because my IntelliSense for VS 2013 is so slow.
I got it working with the help of this tutorial and the video, thanks. The problem I am facing now is that I want to develop for UT and I don’t know which folders to include, or how to get a list all the includes I need. Can I extract this from the Visual Studio project somehow?

anonymous_user_f948c656 · June 19, 2015, 8:09am

Hi there!

I know this is an old topic, but it has been so useful to me in order to get unreal first person shooter into my QtCreator. So, in first place: thank you for your explanation at this forum and the wiki, good job.

Now I have the uproject working on qtcreator, I would like to use some opencv libraries to merge a couple of projects so I though this should be easy if I already have openCV running in my Qt; I only have to add a new INCLUDEPATH and one LIBS += and everything should work but it didn’t

I’ve added the next line to the end of includes.pri:


INCLUDEPATH += "c:\opencv\release\install\include"

And this one after include(includes.pri) at MyQtProject.pro


LIBS += C:/opencv/release/bin/*.dll

These are the lines I have to add to a fresh project in order to get openCV running and available just by adding corresponding includes. I’ve added two includes at MyQtProjectCharacter.cpp


#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"

But when I try to compile the project, QtCreator launch an exception saying that these files don’t exist… :-S

I have checked the url and they are valid, so I can’t figure why I’m getting this issue.

Any idea?
Thank you so much and best regards

Hi !

I’m glad I’ve helped you, btw I’m not the main contributor for the wiki anymore ^^, what you need to understand is that the project file of qtcreator (the .pro) is not the one used for compilation, it exist only for the intellisense feature.

I don’t know exactly what you need to do to include external lib but you should look at your .cs files which is the build system. Take a look to this A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums

Should be pretty close to what you need I think.

Thank you so much ,

I just saw your message, I’m sorry. I though I would receive an email informing a new answer was post on this topic, bit it didn’t. Anyways, at last I could got working my opencv library. Yep, I had to add includes and *.lib to “projectname”.Build.cs indeed.

By the way, I found problems with OpenCV 3.0, so, to get it working, I had to downgrade my OCV version from 3.0 to 2.4.1.0 and everything went fine. That took me so much frustration time, so I hope this post helps as many people as possible.

If someone asks, this is what I added to my “projectname”.Build.cs file. At the end of the constructor method:


if (Target.Platform == UnrealTargetPlatform.Win64)
        {
            PublicAdditionalLibraries.AddRange(new string] { 
                "C:/opencv2410/build/x64/vc12/lib/opencv_core2410.lib", 
                "C:/opencv2410/build/x64/vc12/lib/opencv_highgui2410.lib", 
                "C:/opencv2410/build/x64/vc12/lib/opencv_imgproc2410.lib", 
                "C:/opencv2410/build/x64/vc12/lib/opencv_calib3d2410.lib"});
            PublicIncludePaths.AddRange(new string] { "C:/opencv2410/build/include"});
        }

If you want to try more platforms / modes you should add corresponding libraries

Best regards and thank you again for your response

Hi guys
What’s aboyt CLion?

kassane · April 16, 2016, 6:40pm

The current version of Qt Creator still works with this tutorial?

I did everything according to this tutorial and wiki and at least I can see the highlight of the source code.
Just do not compile directly only in MVS14 or UE4editor!

anonymous_user_101bca4f · January 23, 2018, 2:24pm

Thanks! Works like a charm

Current unreal engine version(4.26) generate a lot of headers files. I’ve take some that generated for visual studio here for anyone experiencing missing includes.
