Feature vs2015 support #339

jonitis · 2015-08-11T07:04:11Z

Visual Studio 2015 is c++11 compliant.
Just had to fix one error about member ref-specifiers.

…tructible_values Support vectors of non-default-constructible values in c++11 mode

Fix compilation warnings about possible loss of data

It seems that your PR got compile errors on MSVC. https://ci.appveyor.com/project/redboltz/msgpack-c/build/1.1.0.82

Recently, I merged many PRs. Some of problems that your PR solves have already solved. Could you review your PR?

I recommend that close this PR once and create another one that is focused on the rest issues.

redboltz · 2015-08-13T01:39:09Z

I misunderstood about your PR. Please ignore above comment. I checked https://github.com/msgpack/msgpack-c/pull/339/files again. I understand that you are trying to support C++11 on MSVC2015. msgpack-c requires many C++11 features on C++11 mode. I'm not sure MSVC2015 supports them. If MSVC2015 support them, it's time to use msgpack-c C++11 mode on MSVC2015.

It seems that the Appveyor uses MSVC 2015. The log message said "Visual Studio 14 2015". So, could you check https://ci.appveyor.com/project/redboltz/msgpack-c/build/1.1.0.82 ?

Hello,
To be frank I had no time to investigate AppVeyor, because I do not understand how it did not fail without may changes. 2 months ago I needed msgpack c++11 headers-only mode. It was broken with Visual Studio 2013 SP5 (probably worked with older SP). But I was able to get it working with then available VS2015 RC (with some tweaks). Now when VS2015 is officially released I can compile my code (no Boost, no exotic containers except std::vector) without problems. The only change was related to tuples and ref qualifiers. At least it did not broke gcc and clang.

redboltz · 2015-08-14T07:53:33Z

Hi @jonitis, thank you for the reply. I understand your situation. Now, I started developing msgpack-c C++11 mode on MSVC2015. However, I got some errors. I suspect that MSVC's bug but I need to write a minimal code to reproduce the bug. Anyway, I will inform you when C++11 mode of the msgpack-c would support MSVC2015.

jonitis · 2015-08-14T08:07:07Z

Takatoshi san, thank you very much for your promptly replies. I appreciate very much how fast you integrated my pull requests etc. Now msgpack fullfills my needs, but if something annoying will show up with VS2015 I will propose at least initial patch. Unfortunately I can't spend too much time on VS, since our main platform is Linux on OpenWrt.

redboltz · 2015-08-15T12:51:12Z

Merged.
All other tests have been passed except the following two tests on MSVC2015. So I removed them from MSVC2015 C++11 build.
See:
1c810bc

In the case that std::tuple contains non default constructible classes, when calling 'as' operation, compiler error is occurred. The error said that default constructor is called from std::tuple. I'm not sure why it happens. That is only one problem that I recognized, so far. I decided to merge the PR with some modification.

If someone remove #if !defined(_MSC_VER) from the code I mentioned above, and would fix the compile error, msgpack-c C++11 support for MSVC2015 would complete.

reza-ebrahimi · 2016-05-12T08:48:54Z

@redboltz Currently still can't use msgpack static library with MSVC 2015 Compiler, it gives me following compiler time errors:

Error   C2955   'msgpack::v1::packer': use of class template requires template argument list 

Error   C2440   'static_cast': cannot convert from 'msgpack::v1::object::with_zone' to 'msgpack::v2::object &'

redboltz · 2016-05-12T11:39:05Z

@reza-ebrahimi msgpack-c passes all tests on MSVC2015. See appveyor result:
https://ci.appveyor.com/project/redboltz/msgpack-c/branch/master/job/fsgdg7jdj4k6bgra

Which code did you get the error?

reza-ebrahimi · 2016-05-13T08:31:13Z

@redboltz Assume that I have a simple class named A:

#include <msgpack/adaptor/define.hpp>
class A {
    A() {}
    ~A() {}
}

When try to build above class with VS2015, compile error happens in msgpack API headers (note that MSGPACK_USE_CPP03 is not defined):

@reza-ebrahimi, could you post a minimal and complete source code that reproduces the error? Even if the error happens in the msgpack-c header, I can't find the reason without the source code.

redboltz · 2016-05-13T08:51:09Z

@reza-ebrahimi, what does the project pictures mean? I need a minimal and complete program.
Could you create it? An instruction to create such code is here:
https://gcc.gnu.org/bugs/minimize.html

reza-ebrahimi · 2016-05-13T08:53:54Z

@redboltz I send to you my test project, please download and compile it, is it ok?

@reza-ebrahimi, thank you! I will check it.

redboltz · 2016-05-13T09:19:51Z

I reproduced the problem. I will fix it soon.

By the way, msgpack-c provides msgpack.hpp for convenience. If you include msgpack.hpp instead of msgpack/adaptor/define.hpp, no errors are detected. It might be a workaround.

Of course, if you include msgpack/adaptor/define.hpp directly, compile errors shouldn't occur. So I will fix it.

redboltz · 2016-05-13T09:33:00Z

I create the issue for the problem. See #463.
