Issue
I have installed raylib and ran the example .c files with success in VSCode and Notepad++.
I'm trying to execute the files from this repo raylib-cpp/projects/CMake
I haven't changed the files from the repo and ran the cmake command directly from VSCoode.
main.cpp
#include "raylib-cpp.hpp"
int main()
{
int screenWidth = 800;
int screenHeight = 450;
raylib::Color background(RAYWHITE);
raylib::Color textColor(LIGHTGRAY);
raylib::Window w(screenWidth, screenHeight, "raylib [core] example - basic window");
SetTargetFPS(60);
while (!w.ShouldClose())
{
BeginDrawing();
background.ClearBackground();
textColor.DrawText("Success!", 190, 200, 20);
EndDrawing();
}
return 0;
}
I tried running the commands as instructed in this github repo: raylib-CMake-example but had errors when I ran make command from git bash in the build folder, I tried mingw32-make too but it didn't work. Then
I installed CMake tools extension in VSCode
and ran the Build command from the extension but got error stating:
inline variables require at least '/std:c++17' [F:\Code\CPP\Raylib\TestGames\Game2CPP\build\raylib-cpp-example.vcxproj]
I'm using Visual Studio Build Tools 2017 Release-amd64 as the kit.
When I tried running the example .c files from raylib I had to change the opengl version from 33 to 21 for the window to properly work.
My folder looks like this:
The output Log looks like this: \

Solution
I can see that there's an issue reported already https://github.com/RobLoach/raylib-cpp/issues/51. I guess that author's default C++ compiler's standard is set to 17, thus there are no issues on his machine. You are one step behind, however. Inline variables, as your compiler suggests, are available since C++17. It appears that you are using some older standard (not sure which, though). Not sure which is the default one for visual studio's cpp compiler.
You can set C++ standard for your project via CMake like that:
set_property(TARGET tgt PROPERTY CXX_STANDARD 11)
Considering this library seems to be 'header-only', you could set CXX_STANDARD to 17 only for your executable. If that raylib library has some objects, though, you'd have to set CXX_STANDARD to 17 in https://github.com/RobLoach/raylib-cpp/blob/master/projects/CMake/CMakeLists.txt for raylib-cpp-example target.
