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