   3 Building GCC 2.0 for 680x0 based Apollo systems requires the GNU
   4 assembler (GAS) version 1.38.1, with John Vasta's patches applied.
   5
   6 If you haven't done so yet, get `gas-1.38.1.tar.Z' from your favourite
   7 GNU distribution site.  Furthermore, get `apollo-gas-1.38.1.diffs'
   8 from `labrea.stanford.edu:/pub/gnu', apply the patches, compile and
   9 install gas (under the name as).  This should go through without any
  10 problems.
  11
  12 After switching into the BSD environment, you can configure GCC 2.0
  13 with the command
  14
  15 % ./configure m68k-apollo-bsd
  16
  17 The Apollo's `/usr/include/setjmp.h' uses a nonstandard `#options()'
  18 construct.  You should create a local copy of this file and remove
  19 these constructs from the declarations of SIGSETJMP and SIGLONGJMP.
  20
  21 The Apollo's `/usr/include/sys/types.h' (BSD Version) doesn't allow
  22 to test for the definition of `size_t'.  This should be fixed by
  23
  24   #ifndef _SIZE_T
  25   #define _SIZE_T
  26   typedef       long    size_t;
  27   #endif
  28
  29 The script `patch-apollo-includes' fixes these two problems, but does
  30 _not_ pretend to be a full fledged `fixincludes' for this system.
  31
  32 If you now follow the standard GCC installation instructions, building
  33 GCC 2.0 (including G++ 2.0) should proceed without any problems.
  34
  35 NB: Debugging is not yet supported for the Apollo.  If someone wants
  36     to do a _big_ favour to the Apollo users, he/she should consider
  37     porting the Binary File Description library (BFD) to the Apollo.
  38     This library can be found in the gdb-4.x distributions or in the
  39     binutils-1.9x distributions.
