Fixed compile error due to duplicate symbols #28

Closed cipherCOM closed 9 years ago

cipherCOM commented 9 years ago

If extern is omitted linker issues arise such as the following:

duplicate symbol _AGKLineZero in:
    /[...]/Objects-normal/x86_64/MyFile.o
    /[...]/libPods-AGGeometryKit.a(AGKLine.o)
ld: 1 duplicate symbols for architecture x86_64

Normally extern should also be applied to all functions, but the constants are especially important due to failing compiles.
