std compile error

Jmelon

hi,
i meet compile error when use std in r19, the specific error prompts and simple test codes are as follows

//main.cpp
#include "c4d.h"
#include "main.h"
#include <string>

Bool PluginStart()
{
   std::string test;
        ...
}

errors:

Error	C2784	'const _Ty &std::_Max_value(const _Ty &,const _Ty &) noexcept': could not deduce template argument for 'const 
                _Ty &' from 'unsigned __int64'    
                e:\visualstudio2017\vc\tools\msvc\14.16.27023\include\xmemory0	45	
Error	C2782	'const _Ty &std::_Max_value(const _Ty &,const _Ty &) noexcept': template parameter '_Ty' is ambiguous		 
                e:\visualstudio2017\vc\tools\msvc\14.16.27023\include\xmemory0	45	
Error	C2672	'_Max_value': no matching overloaded function found	 
                e:\visualstudio2017\vc\tools\msvc\14.16.27023\include\xmemory0	43

it no errors in r20, and if any additional considerations in r19 when use std?

hope your help!

hello,

I've marked your thread as a question, feel free to mark it as solved when you think it is, see this thread for information : Q&A New Functionality.

Regarding your issue, i couldn't reproduce it using both visual studio 2015 and 2017.

You should probably stick to this recommendation regarding the visual studio to use :
https://developers.maxon.net/?page_id=1108

About string you should use our builtin String class. We have a manual with lot of information

Are you trying this with the Cinema4D SDK example or your own project ?
Does this project is coming from r19 or an older version ?

Cheers

@m_magalhaes use r19 sdk , not change any thing, just add two line in main.cpp:

...//other head file
#include <string>
Bool PluginStart()
{
	VERSIONTYPE versionType = GeGetVersionType();

	std::string test;
        ...
}

it will case same error. not only std::string, other like std::vector, std::set also fail. looks like something conflict with std in r19.

Ok, could reproduce it.

That's because of the platform toolset. (using a different Visual Studio)

In your project properties, Configuration Properties -> General -> Platform Toolset you should have Visual Studio 2015 (v140).

If you don't have it, you have to install it.

Cheers

@m_magalhaes thank you! switch to 2015(v140) is all right : )
