Opening webp.dll in Dependency Walker shows that it is linked to kernelXP.dll which is a stub dll included in TuMaGoNX's Xompie project at github to extend the XP API. When I edited the import directory of webp.dll so as to link it kernel32.dll the following imports are missing:
  • InitializeConditionVariable
  • InitializeCriticalSectionEx
  • SleepConditionVariableCS
  • WakeConditionVariable
Therefore kernelXP.dll is required and should be placed in the same directory as webp.dll.
XP FOREVER!
