If the following or similar error is received when compiling the C API the resolve comes by simply adding the ESSAPINU.lib into the project. Don’t just link it, actually add it to the project and recompile to resolve the compile issue.
Error 11 error LNK2019: unresolved external symbol _EssInit referenced in function “void __cdecl ESS_Init(void)” (?ESS_Init@@YAXXZ)
