raygui unusable for C++ projects about raygui HOT 10 CLOSED

It seems related to VS configuration, I'm using raygui to create tools with Visual Studio and it works ok.

from raygui.

I've used the out of the box scripts for raylib to generate the project templates. Could you share what configuration you're using for visual studio to bypass the warnings?

This is very easily reproducible by just trying to compile raylib in any version of VS as part of a C++ project.

@sduman Sorry, I closed it too quickly.

yep sadly unusable in c++ as far as it seems.

getting lots of warnings about { 0 } being used, Types in brackets like (Vector2) or (Rectangle).
also conversions from int to float about 30 errors.
sadly my errors are on german so wont help much to show them

id really like to use raygui!

also doesnt work with extern "C" { #include "raygui.h" }

from raygui.

Tested with g++, lots of warnings but it compiles fine.

Not tested with MSVC just yet.

from raygui.

was using msvc soory shouldve pointed that out

from raygui.

With the include done like this:

#pragma warning( push, 0 )
#pragma warning( disable : 4576 )
#define RAYGUI_IMPLEMENTATION
#define RAYGUI_STANDALONE
#define RAYGUI_STATIC
#include "raygui.h"
#pragma warning( pop )

compiling using visual studio command line tools works as C code, for C++ I get these errors:

raygui.h(1193): error C2397: conversion from 'int' to 'float' requires a narrowing conversion
raygui.h(1495): error C2397: conversion from 'int' to 'float' requires a narrowing conversion
raygui.h(1496): error C2397: conversion from 'int' to 'float' requires a narrowing conversion
raygui.h(1497): error C2397: conversion from 'int' to 'float' requires a narrowing conversion
raygui.h(3971): error C2397: conversion from 'float' to 'int' requires a narrowing conversion
raygui.h(3977): error C2397: conversion from 'float' to 'int' requires a narrowing conversion

It doesn't matter to me because I am using C, but putting it here in case it helps.

MSVC conversion errors are just warnings in g++, they can probably be avoided with an explicit cast.

Warning 4576 is related to compound literals, a C99 feature apparently not supported by C++, despite it works with g++ and clang++. Not sure if disabling 4576 it's enough to work on MSVC C++.

I did a pull request in which I made raygui.h compatible with C++.
In case anyone wants to use raygui.h with C++ you can look at my fork:
