Mostly it's easy. SDCC was making a horrible mess of statics initialized inside a function by generating code to init them, so on Z80 so avoid those but otherwise: Build the binary with the SDCC tools putting the initialization data somewhere unused. Copy the initialization data over the initialized data locations in the binary with a tool on your compiling box And done.. Fuzix does this (and some other stuff) but take a look at the binmunge tools on the Fuzix git tree, particularly the one for applications. If you have to them sorting the static initializers out involves running the app on an emulator, snapshotting just after the constructors and initializers run and then dumping that back out and using it on the real hardware.
