Somehow it's not linking. for the time being, you can add the library file name to the additional dependencies.
Try that and see if it works
I'll check when I get home, but can't think of what it could be.
Everything checks out.
1. create empty project
2. manage nuget and add allegro5
3. open properties->allegro5 and select addons
4. create a main function
Here's my code:
As I asked before, when you selected the addons, did you select them for all configurations?
In this image, I only set the addon for the release configuration.
I got the same linking error because I'm not compiling in release mode.
That's the only thing I can think you're doing.
Anyone else have ideas?
