Seems you are missing a link-library .....
Not sure wether a gcc-version is provided with Miami.
Have you tried finding an SDK for AmiTCP/Genesis ? Maybe in the 3.9NDK ?
There should also be an option to circumvent the need for an link-lib, by
useing compiler-specific #pragmas, but I have no clue how those would have to look
like for gcc-68k :-(
