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.
