Building 'EmptyProject' 2.1: SDL2 for Visual Studio 2015

[joshcamas]

Two days, still haven't been able to write a single line of code I'm dyin' here

Alright, so I'm trying to follow the instructions here: https://ogrecave.github.io/ogre/api/2.1 ... urApp.html

And it didn't work, since it couldn't find the SDL files SDL2Config.cmake or sdl2-config.cmake. I searched my system and could only find a sdl2-config.cmake.in file, which didn't work

So, I followed the advice of this link: https://brendanwhitfield.wordpress.com/ ... with-sdl2/ and grab https://github.com/brendan-w/collector/ ... SDL2.cmake and rename it to sdl2-config.cmake.

This seemed to work, until I tried building the EmptyProject build in Visual Studio 2015. It gave these errors:

Apparently, this is because SDL wasn't built in the same Visual Studio, which is strange cause... it was, right? I built the source.

I'm honestly going insane, I just wanna build a demo

Any ideas how to fix this? Thanks

Is there a folder and two files called...?

Code: Select all

Dependencies/Ogre/include/SDL2
Dependencies/Ogre/Dependencies/lib/SDL2.lib
Dependencies/Ogre/Dependencies/lib/SDL2main.lib

Hmm, following the https://ogrecave.github.io/ogre/api/2.1 ... ndows.html generates as per:



...but pointing (EmptyProject's) SDL2_DIR to any of those (tried them all, to no avail) results in SDL2 not found error.

Got the same issue here, which I ended up "fixing" sort of... This by means isn't any universal solution to anything, but worked for me:

* Instead of using the VisualC dir's projects (which end up with the mess of errors in your post), use cmake(-gui) in SDL2's root as per i.e.:
** source dir: wherever you put SDL2's stuff
** build dir: as above, plus "/build" at end of the path
* compile away (in release mode)
* copy the SDL2.dll to your projects debug/release dirs
* Hardcode the .lib and sdl2 include dirs into your project's OGRE.cmake (where it looks for SDL2)... (I didn't get FindSDL2.cmake to work as intended, so hardcoding the paths I went).
* compile your stuff, and run

...that's about it - unless I forgot something, hmm.

I see what your problem is. Thanks for posting that pic (btw. I did not know about the 'where' command. It's very useful!)

C:\Ogre\Dependencies should point to what currently your C:\Ogre\Dependencies\build\ogredeps folder contains (personally I just store Dependencies repo somewhere, and then use mklink /D Depepndencies pathToDeps/build/ogredeps with admin privileges).

...that made my life a lot easier...
