short salmon I added the #include a the top of the files

#include doesn't link

#

#include is just a dump copy-paste of file contents

short salmon Dec 11, 2023, 9:16 PM

#

#

that's the header file

#

thats the cpp

fading hazel Dec 11, 2023, 9:17 PM

#

short salmon thats the cpp

ok

#

show me your .cpp files in the solution explorer or whatever

#

are all your .cpp files in the sources folder

short salmon Dec 11, 2023, 9:19 PM

#

they're all inside the src folder

#

this is the ofApp.h code

#

#

when i get rid of line 4 and 33 and the sbox.draw(); from the ofApp.cpp the code runs and builds the object
