g++11 update in netbeans(windows)

[N8RzwA7f]

Hi all,

I use Netbeans 8.1 and windows 7 (hate 10).
I updated g++ to the latest version by typing in the command prompts:

mingw-get update
mingw-get upgrade

I then changed the settings of a netbeans project (under project properties)

build, c++ compiler, c++ standard => c++11
build, c++ compiler, addtional options -> -std=c++11


I get the same errors as this guy here (pastebin link)
http://stackoverflow.com/questions/39535875/mingw-update-compile-with-std-c11

and tried the suggested change of -std=c++11 to -std=gnu++11 ,
that did not work.
thanks for the help!

Check the names of the binaries from your folders. It is probably g++.



mingw-get ... is that the original mingw (and MSYS)? There is a fork: mingw-w64 and MSYS2, and there is some other GCC Windows port too (CodeBlocks-page might list it). Better maintained ...

(this reply was irrelevant since trying more). still stuck though

Why do you change any names?

The name of the binary is g++. Keep it as it is. Use it.
build, linker , tool -> g++
build, c++ compiler, tool -> g++

build, c++ compiler, addtional options -> -std=c++11

That does sound like the only option that you have to do/change/set.

You have not actually told which version of g++ you do have now.

g++ --version

[N8RzwA7f]

it says 5.3.0 ?

[N8RzwA7f]

the compiler does not complain about newer header files such as <type-traits> or <chrono>
and some older such as <cstdlib> and <vector>
but complained about <string> and <iostream>

the errors I got were a tooltip : in file included from ..
and then in the debug section: a lot of 'does not name a type' errors.

thanks for any help!

[keskiverto]

Which should be fine.


The iostream and string are not "older headers". Latest standard has them. Therefore,

complaints about

Too vague. If a compiler gives an error message, then you have to know the exact message. We are not psychics, so you have to tell the exact message to us too.

it underlines in red: #include <string>
above main ,and
the errors I got were a tooltip : in file included from ..
and then in the debug section: a lot of 'does not name a type' errors:

c:\mingw\include\sys/stat.h:173:14: error: '_dev_t' does not name a type
struct _stat __struct_stat_defined( _off_t, time_t );

c:\mingw\include\sys/stat.h:180:13: error: '_dev_t' does not name a type
struct stat __struct_stat_defined( _off_t, time_t );

there were more similar errors.
hope you can help

Also
when I had the following #include files at the top

#include <type_traits>
#include <chrono>
#include <cstdlib>
#include <vector>
#include <ratio>

#include <iostream>
#include <string>
#include <array>
#include <iterator>

the compiler complaints that the iostream file is allready included?
but when I comment out the iostream file, it gives tthe same error with string even though the program compiled before without complaints??

anyone?
