[fpc-pascal] FPC 3.2.2 (In)complete Boolean Evaluation on 32bit MacOS
Hello, it seems that the newest 32-bit FPC sometimes creates complete Boolean Evaluation rather than partial, which causes my application to crash. My context is like this: type BOOL=LongBool; PBOOL=^LongBool; function DoSomething(const Cancel:PBOOL=nil); begin if Assigned(Cancel) and Cancel^ then Exit; end; This crashes because Cancel and Cancel^ are always evaluated, even if Cancel is nil. It works fine in 64-bit. Is this a known problem? Cheers, Tobias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

[fpc-pascal] Compilation speed on Apple M1
Hello, first and foremost, many thanks to the creators and contributors of FPC and Lazarus, who enabled me to release my product natively for Apple Silicon only one day after receiving an M1 Mac. Fantastic work! FPC and Lazarus both run natively and work very well. According to Geekbench, the single core performance on the new Mac is around 1.8x as fast as my Intel Mac. Multicore is also much faster. I wonder why I don't see the speed increase in compiling though. Yes I am using different FPC and XCode versions, but I wonder what else could have an influence? My project is very large and not divided into packages, so I frequently need to recompile the whole project. I would be most grateful for any performance tips.

But that firmware is not available for the some of the really old boxes. I admit that it's not important for me to support the old Linux, but I wonder what causes it and if it can be fixed?

Hello, my application uses the AnsiString type to store UTF-8 data. That was totally fine. Now in FPC 3, automatic conversions cause data loss.

What about this code: var a,b:Ansistring; begin a:=Utf8Encode(AWideString); b:=Copy(a,1,10); end; Is "Copy" an RTL routine? Is this OK or not?

So I assume you should use fpsetsockopt before the Connect call. Cheers, Tobias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] FPC 2.4.2 i386 MacOS: Inc broken for Int64's
Hello, my app uses the built-in Inc function to add Int64 variables. Unfortunately, they are treated as UInt32, so the values are truncated as 32 bit values. Wow! That is an impressive bug. I assume it is known? What's the recommendation, which FPC version should I use? Could it be an incompatibility with a specific version of the Developer Tools from Apple?

Re: [fpc-pascal] Widestring Questions
A bug may show anytime anywhere, but the built in ref counted string types are AFAIK thread safe what concerns the ref count per se. I suspect a subtle flaw in the client code is more probable. No, it is a compiler bug. The same code works 100% perfectly on Windows using Delphi, as well as on Mac OS X using FPC 2.2. Starting with FPC 2.4, it loses memory, which can be fixed by using UniqueString in a number of spots in the code. That is proof enough that the compiler has a bug. I am trying to isolate it today by finding out where exactly the UniqueString is necessary.

Re: [fpc-pascal] Widestring memory leaks with FPC 2.4.0?
Unless heaptrc shows leaks when the program exits, no memory leaks happen. It's a leak. The program loses hundreds of MBs of memory just by working with WideStrings. I compared it against FPC 2.2.4 - no leak. An SVN snapshot of 2.5.1 from around 3 months ago also leaks. Will update from SVN now.

[fpc-pascal] Thanks for an awesome tip: -Ur = create release units
Hello, thanks to Jonas for this tip in April! This command line switch can really solve some recompiling problems: -Ur (= create release units) I had the problem Recompiling XYZ, checksum changed for ZZZ when recompiling Lazarus with my component package. It's now solved. For the benefit of everybody I am quoting the original tips again: In some cases, the compiler will want to immediately recompile previously compiled units: a) if you use a unit that has in its interface section a procedure that is declared normally, but which is declared as external. Solution: declare it immediately as external in the interface and remove the version in the implementation b) if you have inline procedures in the interface of unit1 and a unit that uses unit1 is (indirectly) used in the implementation of unit1. Solution: compile everything with -Ur (= create release units; the compiler will never try to recompile such units afterwards, except if the interface section of a unit that it uses has been changed and this other unit has been recompiled).

[fpc-pascal] Mac OS X gdb: Segmentation Fault loading my project

Re: [fpc-pascal] Lazarus Snapshots Intel Mac with FPC 2.4.1?
Another, more seldom reason for recompilation problems is that you happen to name one of your own units the same as a rtl/fcl/lcl library unit.

Which bugs? I'm sorry but it was a few months ago. Before trying again I wanted to make sure I had the best version of FPC available.

Cheers, Tobias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Lazarus Snapshots Intel Mac with FPC 2.4.1?
This usually means that they were compiled by a previous compiler, or that they use units which have been changed and recompiled since the previous compilation. In that case, the compiler will ignore the precompiled unit and try to recompile it. If it then doesn't find the sources, you'll get an error about the unit not being found. Yes but the sources were there. They were in the search path, but the compiler didn't search properly. I will look into it again and if there are bugs, I will fix them in the FPC sources and submit the fixes. (Recompiling XYZ.pas because the checksum changed although it didn't). I deleted all .o and .ppu files and still this happened. I'm not mixing anything. The problem is that FPC sometimes doesn't like its own units - maybe because of different compiler switches?

[fpc-pascal] Re: getting started with threads
But how can I prevent race conditions? If threads X and Y happen to
call the task assignment function at the same time, it seems to me
that they could both be assigned to the same task.
Use for example the cross-platform implementations of
Enter/LeaveCriticalSection. Like this:
EnterCriticalSection(MyCritVar);
try
DoStuff
finally
LeaveCriticalSection(MyCritVar);
end;
Then the main loop can assign a new task by starting a new thread,
whenever it finds one that is finished.
Also possible but not easier. Threads should not be started or
stopped for each task, instead they should wait for an event telling
them to continue with the next task. For example using SetEvent /
ResetEvent as well as:
{$ifdef win32}
WaitForSingleObject(ContinueEvent,INFINITE);
{$else}
RTLEventWaitFor(ContinueEvent);
{$endif}

the Widestring Delete function in wstrings.inc accesses memory beyond
the end of the string. This causes crashes after a while. The Delete
function has been fixed in FPC 2.3 but the fix must be copied to the
earlier branches too. I have submitted this as a bug in Mantis:
http://bugs.freepascal.org/view.php?id=11365
Until it is fixed, developers can just use the fixed code below instead
of the one in the System unit. You just need to find out if your
platform uses FPC_WINLIKEWIDESTRING or not. On my platform, MacOS X,
this is not defined.
Type
PWideRec = ^TWideRec;
TWideRec = Packed Record
{$ifdef FPC_WINLIKEWIDESTRING}
Len : DWord;
{$else FPC_WINLIKEWIDESTRING}
Ref : SizeInt;
Len : SizeInt;
{$endif FPC_WINLIKEWIDESTRING}
First : WideChar;
end;
Const
WideRecLen = SizeOf(TWideRec);
WideFirstOff = SizeOf(TWideRec)-sizeof(WideChar);
Procedure Delete (Var S : WideString; Index,Size: SizeInt); overload;
Var
LS : SizeInt;
begin
If Length(S)=0 then
exit;
if index=0 then
exit;
LS:=PWideRec(Pointer(S)-WideFirstOff)^.Len div sizeof(WideChar);
if (Index=LS) and (Size0) then begin
UniqueString (S);
if Size+IndexLS then
Size:=LS-Index+1;
if Index+Size=LS then begin
Dec(Index);
System.Move(PWideChar(S)[Index+Size],PWideChar(S)[Index],
(LS-Index-Size+1)*sizeof(WideChar));
end;
Setlength(s,LS-Size);
end;
end;
Kind Regards,
Tobias Giesen

[fpc-pascal] Re: FPC on Mac OS X
Hi Sandy, FPC is just the command line compiler. I suppose you could integrate it with Apple's XCode, but the real GUI that goes with it is called Lazarus. The installation is a bit complicated but it will make you very happy. The instructions are here: http://wiki.lazarus.freepascal.org/OS_X_Programming_Tips And the discussion list is here: http://www.lazarus.freepascal.org/mailman/listinfo/lazarus Kind Regards, Tobias Giesen Super Flexible Software Ltd.

[fpc-pascal] no_dead_strip not recognized by OS X 10.3 assembler
Hello, I am now trying the latest Lazarus snapshots on OS X 10.3 on a powerpc Mac. The application compiles 99% fine but at the end it fails with the following errors (from the assembler, I assume): unknown section attribute: no_dead_strip [...] Error while assembling Exit Code 1 Is there a solution for this problem? Thanks! Cheers, Tobias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Compiling / Make problems, latest SVN
Hello, thanks for the new Makefiles! I am now at SVN rev. 8988 and when I enter cd fpc/compiler make cycle CPU_TARGET=powerpc I get: Makefile:125: *** Compiler ppcrossppc not found. Stop. I don't know what's happening. In this step, I do not want to crosscompile. I want to _make_ the cross-compiler. Thanks for any help!!

Re: [fpc-pascal] no_dead_strip not recognized by OS X 10.3 assembler
Yes, add the -CX- -X- command line options. Or better: turn off all smart linking related options in Lazarus. Thanks! I did both, but somehow the error is still there. All the units compile fine, only the last step where the .dpr file is compiled fails. The .s file of the main program remains in the folder. Can I edit it and do the final steps manually, just for a test? Cheers, Tobias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] Compiling FPC 2.3 with FPC 2.2 (Mac OS i386)
Hello, I have installed FPC 2.2 from the Lazarus snapshots. Now I am trying to compile the latest FPC sources from SVN. A few weeks ago, this worked but now I get: variants.pp(518,14) Fatal: Unknown compilerproc fpc_copy_proc. Check if you use the correct run time library. How can I check this? According to my fpc.cfg file which came with Lazarus, the compiler should automatically go into the correct folders for its library: -Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget -Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget/* -Fu/usr/local/lib/fpc/$fpcversion/units/$fpctarget/rtl The reason I want to recompile is the improvements to tppumodule.search_unit. In Lazarus, I often have to rebuild the whole project because files are not found when I only hit F9. Have the improvements to tppumodule.search_unit been ported back to version 2.2 yet? Where can I get the 2.2 sources? Thanks.

[fpc-pascal] Re: Compiling ... Got it working
Hello, I cleaned up some folders, deleting files from previous compilations and updating to the latest SVN and now it's working. FPC 2.3.1 finds my files much better than 2.2. Maybe the improvements in fppu.pas (tppumodule.search_unit) could be ported back to version 2.2 so that other developers will enjoy them too.

[fpc-pascal] Compiling FPC 2.2 on Mac OS X / i386
Hello, I would like to compile FPC. Do I need a special make tool? When I type make all, I get many error messages, apparently because the make tool from Apple is not the right one.
