linker cannot find definition of d3dx11createeffectfrommemory function. function part of effects11 framework. , need link effects11.lib build program.

previously, develop directx apps, must have been directx sdk installed. stand-alone directx sdk concerned legacy , part of windows sdk (since version 8.0). you`ve got when installed visual studio 2012.

the problem sdk version doesn't include effect11 framework, among other things.

there several ways fix problems:

  1. download , install legacy directx sdk. when compiling warnings, because of conflicting old directx sdk , new windows sdk. solve can switch project v110xp toolset or install windows 7 sdk , switch v100 in project's options.
  2. in case of sample program, mr. luna included compiled libs in common folder of source code archive. i'm not sure if work win8 sdk.
  3. correct source code , strip out effect11 stuff. if learning directx, not easy way.
