问题
I'm really new to programming in C++ and I've seen some tutorials of this programming language.
I'm using Dev-C++ 5.11.
So I wanted to make a game seeing a tutorial on YouTube, and a step was to set up SDL2 correctly. So I started searching on Google and tried a few things that some pages explained. But it kept showing up errors. Here's the last tutorial I tried with:
The compiler log (It's a bit messy):

So... What else can I do? Have I done something wrong? Do I have to do an extra step?
(This is the first question I ask here, so tell me if I'm doing something wrong) (I'm not native English speaker too, so if I've misspelled something, that's why)
回答1:
Bloodshed's dev-cpp is not maintained anymore. You can avoid many issues by using a different IDE.
Some free IDEs:
- Code::Blocks
- Visual Studio
- Eclipse
And for tutorials on SDL, you have lazyfoo.net.
回答2:
I've seen there are some multiple questions related to how to configure Dev-C++ in order to work with SDL2 libraries.
First of all I recommend you to execute the IDE as an Administrator mode.
Once IDE started, set the SDL directories as follows:
Tools -> Compiler Options
Binaries directories
Libraries directories
Include directories
Bear in mind your compiler version, in my case I work with x86 directories instead of i686.
On the other hand, I add the includes in the code as:
#include "SDL.h"
#include "SDL_image.h"
#include "SDL_ttf.h"
#include "SDL_mixer.h"
At last but not least, you have to configure your project options:
Project -> Project Options
Add linker parameters:
And that's all.
I hope it helps you and other mates that have problems with SDL2 setup in Dev-C++ IDE.
