Why is this difference Delphi/FPC appearing and what can I do?
Either you use {$MODE DELPHI} or you prepend the method with @, i.e.
FTimer.OnTimer := @OnCheckTimer
I think that Luca's code doesn't work on delphi either.
He should write
FTimer.OnTimer := OnCheckTimer;
Without the self parameter self.
If you add the parameter self, delphi would think you call method
function called OnChecktimer. As OnCheckTimer is a procedure, not a
function, rises error.
If OnTimer wouldn't had parameters, there could a confusion, that IMHO
FPC with @ solves in an elegant way. With a parameter there is no
ambiguity, that's an error: Assigning to variable the result of procedure.

Great to see you back on this issue ! Thanks a lot. Unfortunately, for me, right now Lazarus is just a hobby task, as I don't have any real application for it at the moment. But I still am lurking, and eager to finish the work in progress I have been starting, before we (company) decided not to use Lazarus in the way that I have been suggesting. An hence I am very busy with other (ANSI C based embedded) stuff. If you want to help with activeNoGUI the first thing that is needed to be done is verify if a current standard distribution of Lazarus will install an fpc version that provides TThread.Queue. If this is given I will re-test the code I did for the activeNoGUI interface unit (that provides TApplication etc). Then I could send you the code to do more testing and provide suggestions. If we are happy with the results we could investigate how it is possible to have it integrated in the Lazarus IDE as an additional selectable Widget Type.

Re: [Lazarus] Newbie, porting class to FPC but get procedure assignment error
ALMOST SOLVED (workaround found) As patspiper has posted there has been a potential bug discovered in the fpc linker while tracing my problems with porting the Sentinel SuperPro dongle handler class from Delphi to Lazarus/FPC. In order to port it we had to convert an OBJ file from the dongle maker to a format FPC accepts (coff) using a 3rd party tool, which also has some bug in it. Patspiper will handle the bug reports. The solution to the actual problem for me was: 1) Convert the OBJ file to COFF and alias the internal identifiers such that FPC can find them. This uses the 3rd party tool objconv. Then replace the include directive for the OBJ file with the COFF file. 2)Use the compiler switch -Xe in order to link externally. Much slower but results in a working application. Many thanks to patspiper who has spent a lot of time helping me to track down the cause of the problems! -- Bo Berglund Developer in Sweden -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

But it is unknown to the debugger. - Either FPC did not generate the info when compiling - gdb has a bug reading the issue - the IDE does display incorrect In the last case the breakpoint would actually work. For the IDE does not check for the blue dot. IT just displays it, but does not use it for any check when setting the breakpoint.

Re: [Lazarus] Invisible Breakpoint
Do you at any time replace (e.g. copy and paste -- undo/redo -- delete-all/undo ) the content of the entire file? Or at least from line 1 to the line with the breakpoint? undo only undoes the text, but the breakpoint pos might in some cases be off, after the undo. replacing lines, moves breakpoints in the replaced range, to (iirc) the top of that range. On 24/06/2015 16:55, aradeonas wrote: Yes,File is correct,I removed a breakpoint and change code but debugger think its still there. Yes line exists but Line/Length column in BreakPoint viewer is 0 most of the times. Ok it all sounds as if some part of the IDE thinks there is a different file. Is it a file in your project (main folder or via some path), or is it in some package? Do the logfile anyway, it should tell what filename and path the IDE sends to GDB. And also the line number. (see below) line is 0... Interesting. Yes I edit file.But I dont know what you mean from blue dots. When you run your app, there should be blue dots in the gutter for any executable line. Intersting is BreakPoint viewer show there should be a breakpoint but code editor doesnt and debugger think there is so BreakPoint viewer and debugger think same. Where exactly does the debugger stop in that unit? First line of first procedure? Or the actual line in which the breakpoint used to be, before it became corrupted? -- Some background. A breakpoint at line 0 can not be shown in the editor. (since first line is 1). However if setting a breakpoint in gdb to a line with no code (line 0 has no code) gdb searches the next line with code, and sets it there. (set a breakpoint on an empty line, will stop on next line) This can be useful (if its just 1 or 2 lines off), and harmful if its 100 or more lines away (e.g. in the interface section) So if you stop at the first line of code in the unit, then you got a breakpoint at line 0, and that can not be displayed in the editor. The question is, how it moved to line 0. Something else: 1) when you edit a file while NOT debugging, breakpoints move as you insert/delete lines (obviously) 2) edit a file while debugging, they still move, but only in the IDE. Because the exe in the debugger still needs the old positions. So if procedure Foo is at line 500 to 550, with a breakpoint (in foo) at 510; and you delete 5 lines somewhere before 500, then in the SourceEditor Foo is from 495 to 545 (but the loaded exe still is from 500 to 550) The IDE then maps the breakpoint (that is now displayed at 505) to still stop at 510 (in loaded exe). This map is reset when the debugger stops. Maybe there is an issue with that map... -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
