I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#.

I have the .lib files linked in and everything has been going smoothly so far. Upon wrapping the latest .h file, I hit a snag when 2 functions came back with the link error:

error LNK2019: unresolved external symbol __imp__htonl@4 referenced in function "public: void __thiscall Field::setCharacter(unsigned char,int)" (?setCharacter@Field@@QAEXEH@Z) myutils.lib

I have referenced "myutils.lib" in the linker options, so that shouldn't be the issue.

What's strange is that I have about 20 functions in this particular .h file and all of the rest are linking just fine except for 3 functions.

Any ideas?
