[comp.os.minix] Is 16-bit gdb or gcc possible?

marke@richs118.cpg.trs.reuter.com (Mark Ellis) (04/24/91)

Seems like quite a few people out there are using the gnu 'C' compiler and
debugger.  Is it possible to create these tools using the small model, or 
is this only possible running under the 32-bit version of Minix?  Thanks!

The "small model" on MINIX for the 8086 and 80286 is unfortunately too
small for much of the GNU software.  gcc consists of a number of
programs all of which has code sizes bigger than 64k let alone that
their data/stack size needs to be much larger than that.  In fact it
is difficult to run these tools on machines with less than 4Meg of
RAM.  gdb is a 400k binary and needs 2-300k of memory to run even the
smallest of programs.

So in short that answer is no these things will only be available
on the 32bit version (386 or 68k -- though I don't know about gdb on
the 68k yet)
