I am suddenly getting this message when trying to open my project file. I do not use any C++ (Yet) in my project. And I’m not sure where this is coming from.
When the dialogue asks if I want to rebuild it, if I hit yes, it tells me it can’t, and just closes. If I re-open the project and tell it no, it opens just fine. How do I track down what is causing this and get rid of it? The only thing I can think of as to why this is popping up is that I may have accidentally clicked on adding a new C++ actor, but cancelled out of that. Possibly?
Thanks for any assistance in getting rid of this. It (so far) appears to be relatively harmeless and simply an annoyance, but I don’t want to run the risk of this becoming a problem down the road.
(I’ve looked at other answers to this, but those all seem to have been related to projects that actually do use C++, and those seem to recompile just fine, but still had the message pop back up next time.)
I have the exact same issue - it is a test project so I just keep on clicking NO which just launches the project anyways. If I click yes, the exact same thing happens as you described - I get an error that it cannot compile and nothing happens after that. I have to add that part of the error popup is a suggestion to build manually, but have no idea how to do that? I did not use any additional c++ beside what was already in the template which was working fine on numerous previous occasions. I was trying to delete the Intermediate/source location, but it always recreates it in the same way on launch. It is just bothering me not knowing why is this happening and how to fix it…
I’m not sure if that can help, but we can try to generate vs project file (right click on your project), open the .sln file of your project and start a debug session in visual studio. If the project don’t start, it’s because there is an error somewhere (but normaly it will not have error if you don’t have C++).
