Whether I'd be having fun is probably debatable but it may be fun for many ;) And then, you know the steps : first they laugh at you... Yes, I don't want to spoil your fun. I even do such things myself sometimes. See the port to Native NT (which also allows you basically to write Windows NT drivers). But the developers on a Linux kernel list might not be that open minded ^^ I have hopes that ReactOS might be usable for some embedded stuff, and it is good to know if I need any custom drivers that something exists in FPC. :) It's not fully implemented currently. The last big update from me was to get the RTL nearly completly running for user mode applications. I haven't tested it inside kernel mode yet. But even if it works I wouldn't recommend to use the functions provided by the RTL inside a device driver, because you have to less control over what happens inside those functions (especially regarding paged vs. non-paged memory). The state of the kernel mode part of Native NT is currently this: * only legacy type device drivers tested (none of the more current driver frameworks) * no usage of the kernel's exception handling (also applies to user mode); currently you'd need to do this manually in assembler * no thread related functions * only x86 currently It should be not a big problem to enable x86_64, but currently I don't have a machine to test this (when I upgrade my "server" I hope to be able to run x86_64 Windows in a VM). I also plan to add ARM support once ReactOS' ARM port can boot to user mode (I'd need to test this...)

I have posted

This contains all 4 files needed for compilation, also moved the {$LINK } to the

my touch to the files but went extra mile to keep the original author
(hopefully) happy.
It builds and insmods/rrmmods, printing Hello World and Bye-bye into dmesg ;)
(this is trivial enough code that I don't think it should eat my computer, so I
didn't bother with UML ;) or just like living dangerously... )
Why I decided to take the printk() definition out of system.pas ?
Well it seems to me more like 'Pascal way' that way. I think my next move would
be to put all the available versions of printk() (and all you can think of that
should be associated with it, but not module specific) into linux/printk.pas or
whatever would be appropriate and find out if it can be just added into the
'uses' section of the main kernel module pascal code... (implementation/uses,
probably ?)
(That way it should also be easier to track the never-changing-story of kernel
internals ;)
But that's for another hour of fun next time round ;)
For now,

createbranch.sh is not relevant for you, don't worry about it. Go to
fpcsrc ("cd fpcsrc") and use the make command proposed in the other e-
mail.

Most probably the former. This is the contents of the fpcbuild SVN repository, fpcsrc is inside this one (as suggested by the directory listing).

Re: [fpc-pascal] FPC 2.x for old Solaris
Mark Morgan Lloyd wrote: Thanks for that, noted for next time :-) The solution turned out to be fairly easy: the Solaris compiler uses dynamic libraries since some (libm) don't exist in static form on 10 and others (libmd5 etc.) don't exist in static form at all. Taking ppcsparc from 10 and running it on 8 failed because it was linked against libm.so which was a symlink to libm.so.2, it was resolving that at link time so required libm.so.2 rather than libm.so. However libm.so.1 is on Solaris 10 and simply changing the symlink before linkage created a binary that would run on both 10 and 8. So the remaining question is whether it it possible to tell FPC build to always link against libm.so.1 rather than using the symlink, since messing around with the symlink would obviously be undesirable on a system with multiple users. As noted elsewhere I've got FPC on Solaris 10 to the state where it will compile (but not fully link) Lazarus, fpGUI appears OK so we're probably at a state where lazbuild on simple projects would work. FPC 2.4.2 is OK on both Solaris 8 and 10, including the fp text IDE (without mouse or debugger support). Minor patches in bug 0018271 might be a prerequisite. I'm not trying Lazarus on Solaris 8 on account of missing libraries etc. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] D-Bus. Non blocking listening for signals
I found another way to register own callback events (this is example
which connect to Pidgin instant messenger):
var
VTable: DBusObjectPathVTable;
function MessageHandler(connection: PDBusConnection; message_: PDBusMessage;
user_data: Pointer): DBusHandlerResult; cdecl;
begin
MemoLog.Lines.Add('New signal');
Result := DBUS_HANDLER_RESULT_HANDLED;
end;
function BusConnect: Boolean;
begin
Result := False;
dbus_error_init(@err);
MemoLog.Lines.Add('Listening for signals');
{ Connection }
conn := dbus_bus_get(DBUS_BUS_SESSION, @err);
if dbus_error_is_set(@err) <> 0 then
begin
WriteLn('Connection Error: ' + err.message);
dbus_error_free(@err);
end;
{ Request the name of the bus }
ret := dbus_bus_request_name(conn, 'im.pidgin.purple.PurpleInterface',
DBUS_NAME_FLAG_REPLACE_EXISTING, @err);
if dbus_error_is_set(@err) <> 0 then
begin
MemoLog.Lines.Add('Name Error: ' + err.message);
dbus_error_free(@err);
Exit;
end;
// add a rule for which messages we want to see
dbus_bus_add_match(conn,
'type=''signal'',interface=''im.pidgin.purple.PurpleInterface''', @err);
// see signals from the given interface
dbus_connection_flush(conn);
if (dbus_error_is_set(@err) <> 0) then
begin
MemoLog.Lines.Add('Match Error (' + err.message + ')');
Exit;
end;
MemoLog.Lines.Add('Match rule sent');
VTable.message_function := @MessageHandler;
if dbus_connection_try_register_object_path(conn,
'/im/pidgin/purple/PurpleObject', @VTable, nil, @err)=0 then
MemoLog.Lines.Add('Cant register');
if (dbus_error_is_set(@err) <> 0) then
begin
MemoLog.Lines.Add('Error in register (' + err.message + ')');
Exit;
end;
Result := True;
end;
But this same problem like with dbus_connection_set_wakeup_main_function
- It works only on my computer (64 bit ubuntu). When I send this
executable to my friends or compile and run on 32 bit ubuntu, then
MessageHandler is never called. dbus_connection_try_register_object_path
return TRUE and error is not set, so I don't know what is a reason. But
this is another proof that something is wrong with receiving callback
events by free pascal dbus. I have no idea what blocking this on other
computers. Firewall? Missing some librarys? On each computer is same
libdbus library.
