Development package throws error but IDE build doesn't

[DjAs]

When i’m trying to package a development build for my project in unreal engine, it throws in the log messages:

UATHelper: Packaging (Windows): F:\Unreal Projects\REDACTED\Source\REDACTED\Public\Common\Core\Use.h(27): error C2143: syntax error: missing ';' before '*'
UATHelper: Packaging (Windows): F:\Unreal Projects\REDACTED\Source\REDACTED\Public\Common\Core\Use.h(27): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
PackagingResults: Error: missing ';' before '*'
UATHelper: Packaging (Windows): F:\Unreal Projects\REDACTED\Source\REDACTED\Public\Common\Core\Use.h(27): error C2238: unexpected token(s) preceding ';'

The Specific Line is this:

UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category = "Components", meta = (AllowPrivateAccess = "true"))
	UBillboardComponent* Billboard;

Although when i build with IDE there is no such error. Even when i’m playing in editor it’s fine without problems. I recently have reorganized cpp and header files, but i have deleted Int, Build and Saved files and rebuilt. How can I fix this?

UBillboardComponent

I’m guessing that in that file you are not including the header to UBillboardComponent and you have not forward declared it.

Try changing it to

UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category = "Components", meta = (AllowPrivateAccess = "true"))
class UBillboardComponent* Billboard; 

and be sure to add include “BillboardComponent.h” in your Use.cpp (with needed directories in front of it)

It fixed it by forward declaring it. But I was thinking why didn’t the IDE flagged this error on build. I’m thinking it might be because i had already included the “BillboardComponent.h” in the “Use.cpp”.
