Problem compiling (hpl.h)

[MrBigzy]

Wp64 is deprecated I guess, I think it only pops up as a warning for you so it shouldn't be a problem.

The main problem is linking the header. Did you set up your include folder to find hpl.h in the project settings? (You might also have to set up the lib folder and add the lib file to linker/input/additional dependencies, if there are lib files)
