Hi
I’v done my little (c++ based) project and now I want to package it … but here comes the troubles …
I want to package it for x64 windows (as a starting point).
First it compiles sources …
... many, many cpp files :)
MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: TowerDefence.cpp
MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: [28/28] Link TowerDefence.exe
MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: Creating library D:\UnrealEngine4\Projects\UE4Defender\Binaries\Win64\TowerDefence.lib and object D:\UnrealEngine4\Projects\UE4Defender\Binaries\Win64\TowerDefence.exp
MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: -------- End Detailed Actions Stats -----------------------------------------------------------

MainFrameActions: Packaging (Windows (64-bit)): UE4Build.CheckBuildProducts: Build products *******

MainFrameActions: Packaging (Windows (64-bit)): UE4Build.CheckBuildProducts: D:\UnrealEngine4\Projects\UE4Defender\Binaries\Win64\TowerDefence.pdb
MainFrameActions: Packaging (Windows (64-bit)): UE4Build.CheckBuildProducts: D:\UnrealEngine4\Projects\UE4Defender\Build\Receipts\TowerDefence-Win64-Development.target.xml
MainFrameActions: Packaging (Windows (64-bit)): UE4Build.CheckBuildProducts: End Build products *******
MainFrameActions: Packaging (Windows (64-bit)): Project.Build: ********** BUILD COMMAND COMPLETED **********
MainFrameActions: Packaging (Windows (64-bit)): Project.Cook: ********** COOK COMMAND STARTED **********
so it managed to compile the *.exe, now time to cook some levels & UIs, and here comes the trouble …
LogInit:Display: Failure - 325 error(s), 6916 warning(s)
ohh holy sh***
all the errors are related to interaction of c++ code and blueprints
it all starts easy with a warning about
[2015.09.25-21.04.49:505] 0]LogInit:Display: LogLinker:Warning: Can't find file '/Script/TowerDefence'
[2015.09.25-21.04.49:505] 0]LogInit:Display: LogUObjectGlobals:Warning: Failed to load '/Script/TowerDefence': Can't find file '/Script/TowerDefence'
(my game module is TowerDefence, but I dont even have /Script directory under content) - so I dont know what he is looking for …
if it looks for module object, my c++ for it is prety standard:
class TOWERDEFENCE_API FTowerDefenceGameModuleImpl : public FDefaultGameModuleImpl
{
public:
virtual void StartupModule() override;
virtual void ShutdownModule() override;
};
void FTowerDefenceGameModuleImpl::StartupModule()
{
FDefaultGameModuleImpl::StartupModule();
// some code but disabled while WITH_EDITOR is not defined
return;
}
void FTowerDefenceGameModuleImpl::ShutdownModule()
{
FDefaultGameModuleImpl::ShutdownModule();
// some code but disabled while WITH_EDITOR is not defined
return;
}
IMPLEMENT_PRIMARY_GAME_MODULE( FTowerDefenceGameModuleImpl, TowerDefence, "TowerDefence" );
and then things go completly crazy

my blueprint Medikit derives from c++ class PickupHealth … any ideas why while cooking my c++ classes are not visible anymore ? (game works just fine inside editor)
and finally all blows up
[2015.09.25-21.04.49:504] 0]LogInit:Display: LogBlueprint:Error: [compiler DefaultDefenderMeleAniBP] Error Could not find a function named "GetState" in 'DefaultDefenderMeleAniBP'.
and tons of anothers from blueprints that cannot find c++ classes anymore
ANY IDEA whats going on, and why I cannot cook package ?
(the only idea I have is that somehow the packaging tool did’nt load the game module and now knows nothing about c++ side of the project, but the module is compilled without any errors)
Thanks for any ideas to check/solutions.
