December 13, 2017 How to statically link Derelict SDL2 satellite libs | ||||
---|---|---|---|---|
| ||||
I'm on Linux 64 bit, all SDL libraries (-dev versions) are installed, dub is set up with: "dependencies": { "derelict-sdl2": "~>3.0.0-beta" }, "subConfigurations": { "derelict-sdl2": "derelict-sdl2-static" }, "libs": ["sdl2"] All the SDL core library functions work fine but when I try to use SDL_image library's IMG_Load() or IMG_LoadTexture() I get a linker error, for example: undefined reference to `IMG_LoadTexture' collect2: error: ld returned 1 exit status Error: linker exited with status 1 dmd failed with exit code 1. I have: import derelict.sdl2.image; at the top of my program. I'm guessing that the "libs" section of my dub subConfiguration needs to include the name of the image satellite library? |

Yes, you need to link with SDL_image. https://www.libsdl.org/projects/SDL_image/ |

Sorry Mike, just noticed the end of my original question was missing: I have SDL_Image installed (dev version) but can't see how to refer/add it to the "libs" section (if that's how it gets linked in?). Totally new to D, dub and SDL and using only a text editor rather than an IDE so a bit befuddled!

Should be:
"libs" : [ "SDL2_image", "SDL2"]

I think I did try that but in lower case, which didn't work. I was following the example dub file on this page: http://derelictorg.github.io/packages/sdl2/ which uses lower case... "libs": ["sdl2"] However, I now find that I can reference that core library in upper or lower case in dub.json whereas 'SDL2_image' has to be in that precise case. Maybe something to do with symlinks on my computer...? |
