Hi list,

I've been extending fpcup, trying to add Win64=>Win32 cross compiler ... see latest revision on
https://bitbucket.org/reiniero/fpcup/changesets

With FPC trunk, I get this error:
fpcdefs.inc(216,2) Error: User defined: Cross-compiling from systems without support for an 80 bit extended floating point type to i386 is not yet supported at this time

Is there anything I can do about this?

Thanks,
Reinier

Finish the 80 bit floating point emulation routines (/rtl/inc/sfpux80.pp and the files it includes) and integrate their use into the compiler.

Thanks Jonas,

Very clear answer, thanks. Having had a brief look at the softfpu code I suspect it's out of my league (at least as far as getting error free results)...
