I have the latest version of UE 5.0.1 installed.
I’ve even made sure it’s updated. I’ve successfully created “blank” template starter games, added C++ to them, and it works fine.
I have the latest version of the Lyra starter game template downloaded.
I even deleted and re-downloaded this.
I have the latest version of Visual Studio 2019 installed, with C++ tool chain (this has worked fine for other projects at other times, too.)
I create a new project from the Lyra Starter Project in EPIC launcher, and place it in D:\UEProjects\LyraStarterGame
I open the project.
I press the “compile” button in the bottom-right compile menu.
I get an error message that hot reload failed, because of an unexpected build tool, with a path to my rc.exe executable.
UE builds have always been struck me as less well supported than the main art path, especially compared to products where “clean builds on a variety of targets” is the main deliverable goal. An embedded Linux make menuconfig is quite straightforward, by comparison, for example.
But, like, … why does this simple flow fail? With all the marketing push behind the Lyra starter game, well produced tutorials, developer support all behind it, how can this basic “press the button on the most standard workflow” flow be broken?
Today, I didn’t want to debug build problems. Today, I wanted to just put some pixels on the screen. But, no. That’s not for today.
Is that in a Lyra github base? I hadn’t realized they’d released one yet.
I had to reinstall windows, so only installed vs2020 (made it an easy decision) but I can confirm that I get the same live code errors, but compiling in 2020 from the project downloaded from the marketplace without it running does build ok on my system.
Following up on this, after trying a few different configuration (and sending a few crash reports — again, plain tools, no local changes) I’ve gotten live coding in Lyra to work.
Yes, I had to install Visual Studio 2022. I had to open it up and make sure a dummy hello world C++ project could be made/built.
Then I selected Visual Studio 2022 in the project settings (it defaults to auto-switcher Visual Studio, which might still choose 2019)
Then I did a Build Project (without live coding) in the UE5 editor, which completed.
Then I quit the UE5 editor.
Then I had to right-click the .uproject in the Content folder, and select “generate visual studio project,” because the projects weren’t generated
already. (“Build project” apparently goes straight to each vcxproj, rather than calling msbuild at top-level.)
Then I had to open up the sln and ctrl-B it in Visual Studio.
Then I opened the UE5 editor again, and enabled live coding, and pressing the compile/reload button worked.
One or two of these steps may not be necessary, but at least, if someone else runs into this problem, and finds this thread, they should be able to repeat these steps. Thanks for the help!
