I also have problems integrating the wrapper into my project.
I included:
NewtonMain.c
NewtonAPI.c
NewtonJointLibraryMain.c
NewtonJointLibraryAPI.c
matrix.c
newton_materials.c
newton_main.c
newton_debug.c
Also I defined "NewtonWorld* nworld;"
like in the examples and loaded the "Newton.dll" and
the "JointLibrary.dll".
I don't get errors so far but I don't know how to start or use Newton. What am I supposed to do?
