code4game / libprotobuf_ue4 Goto Github PK

In your document you mentioned

#include "AllowWindowsPlatformTypes.h" //< before include the header file
#include "your code header file" //< ex: #include "Message.pb.h"
#include "HideWindowsPlatformTypes.h"

But I can not find these two files anywhere.

Hi，I've read your code,I find you didn't updaload android and ios protobuffer.a ,in build.cs ,you did not processer the android and ios platform.I have done the same thing in last year, now i want to configure android and ios platform.

Placing this into ThirdParty folder as instructed does not appear to allow UE4 to find it as a module. Is there some other configuration I need to make to my project for Unreal to find this module?

1>------ Build started: Project: UE4, Configuration: BuiltWithUnrealBuildTool Win32 ------
2>------ Build started: Project: TestProject1, Configuration: Shipping_Game x64 ------
2> Creating makefile for TestProject1 (changes to module files)
2>EXEC : error : Couldn't find module rules file for module 'libprotobuf'.

Hi,

I already compiled protobuf with visual studio 2017 ( static compile in 64 bits)
To validate the result I have developed a simple console application to check if I can use the *.pb.cc and *.pb.h files
Everything is ok

Next step I tried to incorporate in a unreal engine 4 project. Set up a build files

File.Build.cs

...
PublicIncludePaths.Add(ModulePath + "/Include");
PublicLibraryPaths.Add(ModulePath + "/Lib");

    PublicAdditionalLibraries.Add("libprotobuf.lib");

...

But it gave me strange compile errors

1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.11.25503\INCLUDE\type_traits(565): error C4647: behavior change: __is_pod(google::protobuf::internal::AuxillaryParseTableField) has different value in previous versions

Search on web but I haven't mutch success: Example this error is real strange !!!!

"...\MSVC\14.11.25503\INCLUDE\type_traits(565): error C4647: behavior change: __is_pod(google::protobuf::internal::AuxillaryParseTableField) has different value in previous versions .."

Have you tried to compile this source code with recent versions of Protobuf and Visual Studio ?

Protocol Buffer 3.3.0
Visual Studio 2017
Release 64 bits
