Title: Cocoa IDE erroring - rebuilding not possible - cant make full lldb trace?
Post by: MISV on August 03, 2018, 10:50:58 pm
I have submitted this bug today
https://bugs.freepascal.org/view.php?id=34088 (https://bugs.freepascal.org/view.php?id=34088)

Essentially
I am using fpcupdeluxe. Upon startup and other times you get arithmetic error. Trying to rebuild gives access violation.

But I did not get any backtrace or line number information

I some trace of the access violation posted. But the IDE remains unusable to me :( Can anyone else duplicate the problem?

I managed to make some traces of the arithmetic error. I submitted bug report but sofar no response. Can anyone duplicate my problem? I think it is a pretty critical problem if IDE does not work :(

NBut maybe a larger problem for me because I rely on fpcupdeluxe and not setup a Carbon-IDE to compile Cocoa appplications. Maybe that was a way forward...

judging by the log file, I can think that the issue comes from the difference in the order of LCL messages sent.

Though an interesting thing is that the issue comes from "files drop" call:
Code: [Select]
    frame 0000006: 0x000000010079af34 lazarus`MAINIDEBARDROPFILES(this=0x000000010a9c68f0, SENDER=0x000000010a9c68f0, FILENAMES=ANSISTRING [] @ 0x000000010ac70670, highFILENAMES=0) at mainbar.pas:405
    frame 0000007: 0x000000010005fca4 lazarus`FORMS$_$TCUSTOMFORM_$__$$_INTFDROPFILES$array_of_ANSISTRING + 68
    frame 0000008: 0x00000001001eed3d lazarus`-[TAppDelegate application:openFiles:] + 357
    frame 0000009: 0x00007fff4e6741ba AppKit`-[NSApplication _doOpenFile:ok:tryTemp:] + 286
    frame 0000010: 0x00007fff4e253337 AppKit`-[NSApplication finishLaunching] + 2438

So my question is: how do you start the IDE?
- do you double click on a lazarus file (letting macOS to open the IDE for you)
- do you drag and drop the file into IDE or the app icon
- do you simply launch IDE (by clicking on the app icon in Finder or Dock)
- some other way?

I haven't done a stack trace, but I have the same problem when using fpcupdeluxe.

For a while now, I've had to rebuild using lazbuild from the commandline to get rid of the arithmetic error.

Code: Pascal  [Select][+][-]
  1. lazbuild --build-ide= --widgetset="Cocoa"

Then I can run it normally, as well as rebuild through the IDE.

ok, and what happens if you start lazarus.app manually (using lazarus binary)?

Same error - happens in lazarus file no matter how I have tried to start it - but if there are other ways I should try let me know. (I ran lldb against lazarus)

please run lazarus under lldb.
When lldb loads lazarus, and prompts you to enter the first command, please run the following and provide the output:
Code: [Select]
settings show target.run-args

and then continue the execution.

and does it crash with EXC_BAD_ACCESS or Arithmetic overflow?

IF it's EXC_BAD_ACCESS, then try to modify cocoaobject.inc (part of cocoaint.pas)
Code: Pascal  [Select][+][-]
  1. procedure TAppDelegate.application_openFiles(sender: NSApplication; filenames: NSArray);
  2. var
  3.   lFiles: array of string;
  4.   lNSStr: NSString;
  5.   i: Integer;
  6. begin
  7.   if (filenames.count=0) then Exit; // this is a new line
  8.   SetLength(lFiles, filenames.count);
  9.   for i := 0 to filenames.count-1 do
  10.   begin
  11.     lNSStr := NSString(filenames.objectAtIndex(i));
  12.     lFiles[i] := NSStringToString(lNSStr);
  13.   end;
  14.   Application.IntfDropFiles(lFiles);
  15.   if Application.MainForm<>nil then
  16.     Application.MainForm.IntfDropFiles(lFiles);
  17. end;
  18.

Upon startup I get arithmetic overflow.

However, I will try take another look tonight, but I can/could not rebuild the lazarus IDE due to lclextensions issue with missing uses.inc file (on/off problems with fpcupdeluxe trunks - see one of hee above posts)

there was nothing done in the trunk to resolve the issue.
What revision did you use before?

Post by: MISV on August 12, 2018, 03:50:40 pm
At time of writing my initial post,  I have been using at max a 1 day old trunk there. Most likely only hours old, but I don't have revision number.

...But maybe my build was messed up somehow...

what if it's a floating bug?

Maybe depending on if I am installing 32bit or 64bit fpcupdeluxe... maybe different units pulled in or similar... will try test both to see just in case I made an oversight concerning using 32 vs 64 bit cocoa
Title: Re: Cocoa IDE erroring - rebuilding not possible - cant make full lldb trace?
Post by: MISV on August 16, 2018, 01:12:54 am
now it seems to work on both 32bit/cocoa and 64bit/cocoa fpcupdeluxe builds   :)
