Problem packaging plugin containing slate

pDunkl · June 13, 2019, 5:41pm

Hi,

I’ve built a plugin which adds a new widget to the editor, containing one extention of SCompoundWidget and one of UWidget.
It currently only packages in C++ projects, but I also want it to package on blueprint-only projects as well and also be able to put it on the marketplace.
Therefore I need the Edit->Plugins->Package (I think, because it prebuilts the needed files?) but this packager stops and throws back 9 errors (just related to slate macros), here the log:

PS. this is my first plugin, so I’m not sure if I’m missing just something basic or messed something up
btw. Is it posible to prebuilt the plugin for mac/ios if I do not own such device?

Manoel.Neto · June 13, 2019, 5:53pm

That kind of error usually means you are missing an #include somewhere.

BrUnO_XaVIeR · June 13, 2019, 6:03pm


#include "SlateBasics.h"


#include "SlateExtras.h"

pDunkl · June 13, 2019, 6:13pm

Hm I thought so, therefore I checked couple times what could be missing.
For example: before the plugin packager log told me that some headers could not be found (for example IPluginManager) and in thath case I just needed to change it from include "IPluginManager.h "to “Interfaces/IPluginManager.h”.
But after I fixed that I got these 9 slate related errors and the log doesn’t say which header can’t be found, I think it must be someone related with the slate macros, but I can’t find the right one… Any idea?

edit:

ah now it works, thanks Bruno!

note: because those two are monolihic headers it throws a warning, but thanks to you I could narrow it down to the specific smaller one I needed, it is: “Framework/Application/SlateApplication.h”

Another problem occured, I’ve tried now for several hours to fix it, by following a couple posts and Rama’s tutorial about a marketplace plugin creation by using RunUAT.bat… but sadly no succes.

If I try to start the game via Project Launcher this message appears while deploying (for android):



ERROR: Stage Failed. Missing receipt 'D:\UnrealProjects\RadarChartExample\Binaries\Android\RadarChartExample.target'. Check that this target has been built.

and here for Win64 shipping:



ERROR: Stage Failed. Missing receipt 'D:\UnrealProjects\RadarChartExample\Binaries\Win64\RadarChartExample-Win64-Shipping.target'. Check that this target has been built.

Only if I package the project (file->desired platform (with desired build config) first, and than I can launch it with the Project Launcher afterwards without problems but only for the same platform with the same build config.
I think it only happens in a blueprint only project.
But testing with plugins from other people from the marketplace I don’t have to do that, they work at the first place.
I tried (as mentioned) the RunUAT.bat method, the Edit->Plugins->PackagePlugin method, and build inside Visual Studio with selected project config and platform.
I do have the precompiled files in the plugin’s intermediate folder though.
