You inadvertently changed RangeEditor.m from Objective-C++ to Objective-C when
you removed and re-added it:
- CDE3EE891804C87A00201967 /* RangeEditor.m */ = {isa =
PBXFileReference; fileEncoding = 4; lastKnownFileType = sourcecode.cpp.objcpp;
path = RangeEditor.m; sourceTree = "<group>"; };
+ CDBE2D1A1BDFEA7A000BE921 /* RangeEditor.m */ = {isa =
PBXFileReference; fileEncoding = 4; lastKnownFileType = sourcecode.c.objc; name
= RangeEditor.m; path = Menus/MenuItems/Widgets/RangeEditor/RangeEditor.m;
sourceTree = "<group>"; };
So now when RangeEditor.m calls ‘clamp’ it doesn’t mangle the name, i.e. it
creates an external reference to a symbol called ‘_clamp’. But utils.m is an
Objective-C++ file so it implements ‘clamp’ with a C++-mangled name. Thus the
link error.
IMHO it’s better to make the language explicit in the filename by using “.mm”
for Objective-C++ source files. It prevents this kind of confusion.
