Description bluescreen_avenger 2017-07-27 01:19:43 UTC 
Hi

I think its commit 2ee7d2fa299b that caused the issue, the one before it allows it to compile

I am compiling it with
./configure --prefix=$INSTALLDIR --libdir=$INSTALLDIR/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH) --enable-wayland-shared=no
(I might not need the --enable-wayland-shared=no anymore, seems the wayland backend has been working even with that)


It seems I get the below errors

  CC     build/SDL_render_gl.lo
  CC     build/SDL_shaders_gl.lo
/srcbuild/SDL/src/render/SDL_yuv_mmx.c: In function 'ColorRGBDitherYV12MMX1X':

We're working on the MMX assembly issue in Bug #3689.

YUV MMX assembly is temporarily disabled until we figure this out for the various versions of GCC, or rewrite this using MMX intrinsics.
