thejinchao / libprotobuf Goto Github PK

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

...\Include\google/protobuf/generated_message_table_driven.h(159): note: see reference to class template instantiation 'std::is_podgoogle::protobuf::internal::AuxillaryParseTableField' being compiled

...\Messages.pb.h(992): warning C4668: 'PROTOBUF_INLINE_NOT_IN_HEADERS' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
...\Include\google/protobuf/descriptor.pb.h(4113): warning C4668: 'PROTOBUF_INLINE_NOT_IN_HEADERS' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
...\Messages.pb.cc(258): error C4125: decimal digit terminates octal escape sequence
...\Messages.pb.cc(259): error C4125: decimal digit terminates octal escape sequence

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

How to compile arm64 lib for Android

Environment:

• UE4.26.2
• Protobuf 3.19.4
• VS2017
• clang tool chain v17 10.0.1-centos7
• cmake 3.22.3
• PS4 SDK 8.000

Encountered following problems：

1. CMakeList.txt specified to build with c++11, however some header files of PS4 SDK have following macro definitions which caused build failure:

#if __cplusplus<=201103L  
  #error This version of C++ is not compatible with the standard library implementation. 
#endif

I made it work by changing the specified c++ version from 11 to 14 in CMakeList.txt

2. Some header files of protobuf have following code which also caused build failure:

#elif defined(__FreeBSD__)  
#include <sys/endian.h>  // __BYTE_ORDER

Compiler can't find this header file because I am building these files on Windows platform. It works after I modified this code block to

#elif defined(__FreeBSD__)
#define PROTOBUF_LITTLE_ENDIAN 1

3. Finally I don't know how to solve following errors because I am not a C++ developer but a golang developer QAQ

G:\protobuf-3.19.4\src\google\protobuf\arena_impl.h(534,44): error : alignment (64) of thread-local variable 'thread_cache' is greater than the maximum supported alignment (32) for a thread-local variable on this target [G:\protobuf-3.19.4\cmake\build\PS4\libprotobuf.vcxproj]

G:\protobuf-3.19.4\src\google\protobuf\stubs\mutex.h(124,13): error : constexpr constructor never produces a constant expression [-Winvalid-constexpr] [G:\protobuf-3.19.4\cmake\build\PS4\libprotobuf.vcxproj]

I have done what you said. In Editor it works very well. But when I package the game, it gives me errors as follows. But if I delete the libprotobuf folder from ThirdParty it is OK with no error.
