Setup SDL2 with CMake and Visual Studio (Game Development)

Рет қаралды 9,204

Күн бұрын

In this video we create a new CMake project using Visual Studio and work with it directly within Visual Studio, without producing a VS project or solution. We then use find_package to add SDL2 as a 3rd party library and link to it in order to compile our sample SDL2 application. We use SDL_CreateWindow to setup a window and SDL_CreateRenderer to setup the renderer.

hey just wanted to tell you this video was very helpful, while it didn't work 100% because my text editor is /unusual/ I managed to get it working after 3 days thanks 😀 (I got it working just a few minutes after your video)

Thanks, that really helped me set up my very first CMake project with SDL2.

And this did it! Stack overflow and other forums had it wrong or were confusing the whole time

Thanks! Been coding for a long time but needed microsoft's compiler to use nvapi so I'm switching from gcc... was a major pain to figure out how to properly link SDL.

I followed everything but I get this error: Could not find a configuration file for package "SDL2" that is compatible 1> [CMake] with requested version "".

Not sure if you're still interested, but the find_package stuff must be entered in the nested CMake, not the global one

any ideas on why it still fails to generate the files, even after editing the CMAKE_PREFIX_PATH and restarting VS?

which version of SDL2 did you download from github? I used the VC one.

@maartenofbelgium Жыл бұрын

At kzfaq.info/get/bejne/oNGdd6WL38nMkoU.html, the VC sdk was visible. The mingw sdk has a completely different folder structure.

I followed all your steps and the CMake files generate fine but when I try to include SDL.h in the main file I get a "Cannot open include file" error. Do you know what could be causing this issue? Edit: Adding #define SDL_MAIN_HANDLED to the top of my main file fixed this but I don't know what that does specifically if anyone can explain that

@constref1983 9 ай бұрын

Don't set the SDL_MAIN_HANDLED define, this causes SDL to not perform important platform specific setup. If you use pastebin and send me a couple of links to your CMakeLists.txt and main.cpp I can take a look and help.

Is there any way to not copy required dlls to exe directory manually? I mean it looks like a dirty hack I found smth like: set(CMAKE_INSTALL_RPATH ".") set(CMAKE_BUILD_WITH_INSTALL_RPATH true) But I'm not sure it is a clear way as well. Any other ideas? Thanks

@@ezphantom Putting stuff in your project file to copy DLLs around is a far dirtier hack in my opinion. I don't like copying the DLL directly either, but I also don't care enough to waste any more time to do it some hypothetical "right" way. I went down the rabbit hole once and didn't wasted a bunch of time, I may try it again, if I do I'll let you know ;)

@mariusz5682 Жыл бұрын

Manual or post build copying of dll can be avoided directly in Visual Studio: right click project -> Properties -> Configuration Properties -> Debugging -> Environment: (for the relevant configuration and platform!) I hope there is a way to do this from within CMake - and for any generator, not just VS, but i haven't figured it out yet. If anyone knows, please tell. I appreciate the video!

In the interests of portability, rather than installing SDL2 at the system level I've included the SDL2 development package within my project (under a folder dep) and use ``` set(SDL2_DIR ${CMAKE_CURRENT_LIST_DIR}/dep/SDL2/cmake/) ``` to allow find_package to find it. Also to ensure the DLL gets copied to the build directory I've added this to automate this step (where my-project is the project name) ``` add_custom_command(TARGET my-project POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy -t $ $ COMMAND_EXPAND_LISTS ) ``` Rather than manually copying the DLL (which I'll probably forget when setting the project up on a new machine).
