How can I rebuild the source of unreal 4.10?

I’m trying to change stuff and pressing the “Build” option or the “Rebuild” option and it will say it is up to date and successful:

1>------ Rebuild All started: Project: UE4, Configuration: BuiltWithUnrealBuildTool Win32 ------
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

I know i could build the source in earlier versions of the engine, So what is different now?

I know this probably isn’t very helpful, but check your project NMake paths. You might be pointing to the default engine install from the launcher rather than your github checkout of the actual source.

Im not using the githun ver. Using launcher edition.

I’m pretty sure you don’t get the source with the launcher version so there’s nothing to build.

I do have the source. I’v modified some of it and I want to compile it.

All I can recommend is that you check out the github repo, redo your changes there and have another go at building it. This is the method we’re all familiar with.

You can not rebuild the launcher version, you need a source build which you get from GitHub. The launcher build comes with the source just for debugging purpose.

I see, Thanks everyone.
