These are the errors i recieve when i try to build, and I have no clue where to begin in fixing this. Help please?

You're most likely missing an "#include

 

[cpjust]

If the functions you're calling are in a .lib file, maybe you forgot to add it to your Link properties?

Make sure FunctionParser.cpp is added to your project.

hey thanks completely forgot about that, the project apppawseditor was missing a dependecy check for libfparser. appreciate it.
