Hello guys,

Could you give me a clue how to hide this kind of warnings ?

In file included from /usr/include/c++/6/vector:69:0,
from /tmp/tmp.t84kxtTjFo/jsonLib/single_include/nlohmann/json.hpp:49,
from /tmp/tmp.t84kxtTjFo/main.cpp:3:
/usr/include/c++/6/bits/vector.tcc: In member function ‘void std::vector<_Tp, _Alloc>::reserve(std::vector<_Tp, _Alloc>::size_type) [with _Tp = nlohmann::basic_json<>; _Alloc = std::allocator<nlohmann::basic_json<> >]’:

_GLIBCXX_MAKE_MOVE_IF_NOEXCEPT_ITERATOR(this->_M_impl._M_finish));

I have a lot of "will change in GCC 7.1" warnings and it make hard to see real problems.

set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -w")
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -w")
I set this parameters in CMakeLists but id doesn't work :(

Best regards,
Konstantin.

That warning is telling you that there was a subtle ABI change (actually a conformance fix) between 6 and 7.1, such that libraries built with 6.x or earlier may not work properly when called from code built with 7.x (and vice-versa). As long as all your C++ code is built with GCC 7.1 or later, you can safely ignore this warning. To disable it, pass -Wno-psabi to the compiler.

For more details on the context of the change, see the GCC 7 changelog, and the associated bug.

json.hpp version 3.9.1

vector<_Tp, _Alloc>::
^~~~~~~~~~~~~~~~~~~

I don't want to use -Wno-psabi, It's not elegant enough.

Your compiler tells you that an implementation detail of std::vector has changed. There is nothing this library can do about this.

Your compiler tells you that an implementation detail of std::vector has changed. There is nothing this library can do about this.

Thank you for your reply,But json.hpp should be compatible with gcc 8.3.0.
My test program:

    #include<iostream>
    #include<string>
    #include"json.hpp"
    using Json = nlohmann::json;
    int main()
    {
        const std::string str = "{\"test_val\": 654321}";
        const auto &config = Json::parse(str, nullptr, true, true);
        int val = config["test_val"].get<int>();
        std::cout << val << std::endl;
        return 0;
    }

Regarding the warning, we already had an issue #1861 on this in December 2019. There, it was noted that there was a subtle ABI change (actually a conformance fix) between GCC 6 and 7.1, such that libraries built with GCC 6.x or earlier may not work properly when called from code built with GCC 7.x (and vice-versa).

The GCC 7 Release notes https://gcc.gnu.org/gcc-7/changes.html state:

On ARM targets (arm*--), a bug introduced in GCC 5 that
affects conformance to the procedure call standard (AAPCS) has
been fixed. The bug affects some C++ code where class objects
are passed by value to functions and could result in incorrect
or inconsistent code being generated. This is an ABI change.
If the option -Wpsabi is enabled (on by default) the compiler
will emit a diagnostic note for code that might be affected.

As long as all your C++ code is built with GCC 7.1 or later, you can safely ignore this warning. To disable it, pass -Wno-psabi to the compiler. Since you are using GCC 8.3, this should be safe. I could compile the test suite without warnings with -Wno-psabi -Wall -Wextra -pedantic using arm-linux-gnueabihf-g++ 9.2.1 (I did not find version 8.3 yet).

There is nothing wrong with the library.

Thanks a lot.
