Compile Error regarding "PawnTank.generated.h" No such file or directory

[psybr]

Hi there, I am really struggling to solve this problem. Apologies if this has been answered already. i’ve been hunting but couldn’t find the solution.

I had just completed filling out the constructor for PawnTank.cpp (SpringArm and Camera). Once i saved and reopened Unreal and tried compiling the compile failed with the ‘PawnTank.generated.h’: No such file or directory.

Here’s the full Compiler Log:

Here’s what i’ve tried so far:

• Refreshing Visual Studio Code files but no luck
• Deleting Binaries and rebuilding from Source but couldn’t rebuild as the compile still failed
• had to drag Binaries out of Recycle Bin to get the Unreal project open again
• deleting PawnTank.h/.cpp and filling them out again but i failed with the same error at the same spot
• Now I’m lost so i would be infinitely grateful for any help

Here are some screenshots of the PawnTank.h/.cpp:

Also might be worth mentioning I seem to be having a particualrly hard time with Intelisense and permanent red squiggles but i hear its kind of standard for it to struggle with unreal. Still bugs me though

Thanks in advance

Could you try doing the following with Unreal closed

Ctrl + Shift + B > ToonTanksEditor Win64 Development Rebuild

See my post here.

Name followed by '::' must be a class or namespace name

Most of the time when you get a generated.h error its fixed by the following. open where your project is stored on your disk. delete .vs binaries intermediate and saved folders. delete your sln for your project. right click on your project.uproject generate visual studios project files. it will say something about building with a different version and would you like to continue. continue and compile the code before opening your project.

Thanks for the help. I Just ran the Development Build you suggested and got the same generated.h no such file. Here’s the full log:

Appreciate the help Keith.

I tried deleting /vscod /Binaries /Intermediate and /Saved and generated VS project files but it failed with: ToonTanks could not be compiled. Try rebuilding from source manually"

I then tried the rebuild from VSCode DanM mentioned but it’s the same a story.

I’m positive it has something to do with the PawnTank c++ child class so i’m going to delete them and walk through it again. If that fails I guess i could try using VS community or maybe try the unreal 4.22 version of the project. Would that be worth a go?

oh and I forgot to include the vs “PROBLEMS” tab errors

Cheers guys

Okay I think I’ve sorted it out. I managed to implement and compile the PawnTank files.

I tried a lot of things but I think it boiled down to:

• deleting the project directories and generating vs files
• deleting pawntank.h/.cpp - FYI i found a couple of syntax errors in my .h (no ‘;’ after forward declarations but that didn’t fix it. Intelisense missed it somehow)
• setting up the c_cpp…json ‘defines’ again from the bull cow resources
• copied .h and .cpp from lecture git commit
• compile went smoothly!

Im relieved. I was about to throw in the towel.

thank muchly for the support
