I’ve tried to create a C++ project and I have this error, i really don’t know why.

Seems like i don’t have a .h file but i don’t know where to find this file,
I’ve already tried to re-install VS and UE4 but i’ve always this error.

If someone know what to do please help… :’(

The Unreal Engine editor didn’t even appear, it fail at the compilation few time after i click on Create Project",

when it arrive to “Compiling the C++ project”, it crash and i have the error message i posted previously and it ask me to “Open with Visual Studio” or “Cancel”,

i’ve used Windows File Explorer and i’ve found the header files i didn’t noticed it was a header file (no .h at the end of the file), in the WFE it’s called PCH.BatteryCollector.h, so i don’t know if this is the problem (i don’t think), but it’s actually in the good directory

when you say “assuming you’re using Windows”, is this mean you can run Unreal on Linux distrubs ?

If this is an issue caused by the first compilation of an editor-created C++ project (where the user doesn’t have any way to interact with the solution before the first compilation) I believe the issue might have to do with foreign characters in your Windows path.

Create a new project in C:\Development\Unreal Projects\ and see what happens.

It’s worked with your method Shohei, but i don’t understand why.

Can you explain me please ?

It has to do with the special characters in your name. The compiler is probably using ASCII instead of UTF-8, so when it tries to read the accented characters in your name it turns into “Fran??ois Gr??zes” which is a path that does not exist on your computer. Moving the project into a file path that does not include any accented characters will allow the application to parse the path correctly and find the necessary files.

You… you’re the real MVP, thank you very much :slight_smile:
