Title: Check if SFML is installed
Post by: Rhubarb on June 23, 2024, 09:06:21 pm

Hello, is there any #ifdef to check if libsfml-dev is installed? Thanks.

Not really.

If you use CMake to build your application, you could search for it with find_package, which should find it, if it's installed (whatever you definition of "installed" is).

You can use macros not exactly what you ask but still can help you to detect certain header file.

#if __has_include

https://en.cppreference.com/w/cpp/preprocessor/include (https://en.cppreference.com/w/cpp/preprocessor/include)

eg.:

#if __has_include("SFML/System/Vector2.hpp")
    #include <SFML/System/Vector2.hpp>
    #define has_sfVector 1
#else if
    #define has_sfVector 0
#endif // __has_include("SFML/System/Vector2.hpp")

I use __has_include for exactly this. My vector maths class checks for SFML, Box2D and Imgui headers to add casting operators if the required headers are present.
