Hello, I compiled TiME from sources successful, but have black screen when launch t-engine.

Thanks for having fun!

Well. While we waiting for developers answer, I can tell that I found out, that you have nil error, because nil is returned by core.display.loadimage function. In turn, this is info about loadimage function:

-- {"loadImage", sdl_load_image},
--- Creates a SDL surface from an image.
-- @param path Image path relative to the module directory.
-- @return An SDL surface.
function loadImage (path)


So, that can mean only one thing - for some reason, SDL do not like the idea to download png file. Guess it's another SDL mismatch.

You can make following changes to src/core_lua.c:
-1317: if (!*s) return 0;
+1317: if (!*s) {
+1318: printf("IMG_Load_RW: %s\n", IMG_GetError());
+1319: return 0;
+1319: }

And take a look at the output of the error message. In my case it was:
IMG_Load_RW: Failed loading png_set_longjmp_fn: /usr/lib64/libpng12.so.0: undefined symbol: _png_set_longjmp_fn

As I have said - SDL version mismatch.

It's quite inconvinient that I am unable to edit my messages, so I write another post (sorry Moderator, you can kill them if you want to).

All you need to do is update your libpng library. And check sdl dependancies. Than everything should be all right. May be it should be added to wiki, that libpng should be at least 1.5.10?
