Hi Hyde, thanks for clarifying, comments below:

However, being higher level, it depend on lots of other EFL, as Raster named Ecore (main loop, timers...), Evas (canvas), Eina (data types), Eet (binary file chunk reading lib, similar to "zip"). Of course you can port them, as was done for PSL1GHT (PS3 native engine), but it's more work. Maybe you can try this as a second step/milestone. > I'll try to use pre-Eina Evas though I still couldn't get my Win7 + MinGW > right (lots of autotool error) > Did you look into Vincent's wiki page: https://trac.enlightenment.org/e/wiki/EFLWindowsXP He was the last one to care about such setup, and I basically removed most of the support in the current merged tree (the EFL git repo) as we could not get too broad interest from developers to guarantee it would work. Before some guys were doing some work to get it running now and then, it was not constant. >If you need to strip the libraries, I'd recommend to remove the following > chunks from Evas: > > - Gradients: it was removed in current Evas, but the pre-Eina still > contained it with lots of useless code; > > - Textblock: if you don't need text markup or multi-line text, you can > remove this and lots of code. > > I'l need Textblock for further usage. > Ok. Just note that using Textblock from plain Evas is a PITA, I'd recommend getting to it via Edje, but then you need the other libraries as said before. > And of course choose the minimum set of engines and options, I'm not sure > the bootloader can use MMX/SSE, then you can compile out those with > ./configure flags. > Yes, we have SSE2, which is for security check, grab them libs to use will > be okay. > > In UEFI environment we have events and notify, basic Bit blit function to > access raw framebuffer, timers..etc. Not much like the OS but will do some > good. > That's basically what we need. You don't need to port everything, just what you need to make it work. For instance timers and framebuffer access should be enough, as well as file (fopen) if you need Edje/Eet. Edje may use Eio that in turn uses inotify on Linux, but you can leave that as empty stubs or just do not compile. Nowadays Evas also is starting to depend on Threads, thus it's good to plan such feature in the future. > > NOTE: which hardware are you using this?

I'd still recommend to try Evas by itself before going further, but if your plan is to create an "SDK", it's better to continue with upstream EFL on the long run.
