Wellcome to the MacOS port of FreePascal (FPC)
|
||||
Welcome to the MacOS port of FreePascal (FPC)
|
||||
==============================================
|
||||
|
||||
It is considered under construction, at the moment.
|
||||
|
||||
Most of the programs in demo/text works.
|
||||
|
||||
Prerequisites:
|
||||
--------------
|
||||
Please note that compiling must be done on a platform
|
||||
supported by FPC, e g a PC. Then the generated assemble files
|
||||
is to be transfered to a Macintosh with MPW installed.
|
||||
supported by FPC, either in Darwin (MacOS X) or e g on
|
||||
Windows or Linux.
|
||||
|
||||
MPW must be installed on the target Macintosh.
|
||||
|
||||
For compiling with FPC, use it as for other operating systems
|
||||
and add these options:
|
||||
Compiling on host:
|
||||
------------------
|
||||
When compiling for target MacOS, use FPC as for other
|
||||
operating systems with these options:
|
||||
|
||||
-Tmacos # target macos
|
||||
-dpowerpc
|
||||
-al # dont delete asm output
|
||||
-s # dont generate executable
|
||||
-st # dont generate executable, link on target
|
||||
|
||||
Note that at the moment, FPC yells about not supporting
|
||||
creating of executables at the platform, nevertheless
|
||||
it creates all asm files to produce an application on the Mac.
|
||||
If make is used, add OPT=-st OS_TARGET=macos (on foreign platforms
|
||||
CPU_TARGET=powerpc must also be added)
|
||||
|
||||
Note that one must build the RTL by issuing make in rtl/macos, with
|
||||
the above options, to be able to buld other programs. (Currently only
|
||||
system.pp is available)
|
||||
|
||||
|
||||
Use MPW to assemble and link the output from FreePascal
|
||||
Assembling and linking on target:
|
||||
---------------------------------
|
||||
In case that host and target machine is different, transfer the produced
|
||||
files, that is assembler files (*.s) and link script *_ppas, to the host.
|
||||
|
||||
For PPCAsm, use options:
|
||||
On the target, use MPW to assemble and link the output from FreePascal by
|
||||
executing the link script (which is an MPW script), with its directory
|
||||
as current directory. Unfortunatelly the link script does not have the
|
||||
proper file type, so this has to be fixed first e. g with
|
||||
the MPW command SetFile.
|
||||
|
||||
-case on
|
||||
Example: To build Hello World, execute:
|
||||
|
||||
For PPCLink, use options
|
||||
Directory HD:Projekt:FreePascal:fpc:rtl:macos
|
||||
SetFile -c 'MPS ' -t 'TEXT' system_ppas
|
||||
system_ppas #executes the script
|
||||
Directory HD:Projekt:FreePascal:fpc:demo:text
|
||||
SetFile -c 'MPS ' -t 'TEXT' hello_ppas
|
||||
magic_hello #executes the script
|
||||
|
||||
-dead on
|
||||
-tocdataref off
|
||||
-m program_init
|
||||
|
||||
Note on the compiler implementation
|
||||
===================================
|
||||
|
||||
Procedure pointers
|
||||
------------------
|
||||
The entries in the transition vector is used as procedure pointers.
|
||||
That is the symbol xxx[DS].
|
||||
|
||||
Global variables
|
||||
----------------
|
||||
Currently all global variables are indirect, that is the entry in
|
||||
the TOC is always a pointer to data. (In the future small data items
|
||||
may be stored directly in the TOC, but I have not found out how this
|
||||
is supported by PPCLink.)
|
||||
may be stored directly in the TOC)
|
||||
|
||||
Thus all references to globals are via a construct like:
|
||||
lwz rX, yyy[TC](r2) ;loads a pointer to a global into rX
|
||||
lwz rX, yyy[TC](r2) ;loads a pointer to a global into rX
|
||||
|
||||
Debugging
|
||||
----------
|
||||
-g is considered under construction.
|
||||
|
||||
When -g is working, one should be able to see source code
|
||||
in the Power Mac Debugger 2.1 (can be downloaded from Apple),
|
||||
but it will not be possible to examine variables.
|
||||
One can of course examine registers, especially
|
||||
at entry and exit point where the parameter lists is stored
|
||||
in registers, according to the calling conventions.
|
||||
|
||||
A suggestion is to do the main debugging in the darwin version of the
|
||||
program.
