Hi I'm trying to compile a synth target with eCos. I downloaded using the tcl-script, and are running the configtool to select the target. I have set CYGBLD_GLOBAL_COMMAND_PREFIX to empty, to use the system stack, however I cannot get it to compile due to "loss of precision" errors. If I add -fpermissive to the compile I get further but end up with a lot of:
