MacOS Lazarus instance is running but not responding
« on: December 15, 2016, 11:04:01 am »
maybe I have some error in program. When I start to debug clicking green triangle it remains green and red rectangle is red. Nothing else visible. My first form is not visible.  I had to force Quit Lazarus by cmd+alt+esc. BUT: when I try to start Lazarus it writes:
MacOS Lazarus instance is running but not responding
and I had to restart mac...

Please is any better solution?

Have you created an application bundle in the project settings?
function GetRandomNumber: integer; // xkcd.com
begin
  GetRandomNumber := 4; // chosen by fair dice roll. Guaranteed to be random.
end;

What version of Lazarus are you using? It may be a debugger issue. Did you codesign gdb? I use Lazarus on Mac daily with few problems.

Sorry, it was o.k. but it is not, again.

Again the same situation, I had to force end lazarus, because of not responding in status while like debugging, but nothing displayed. And then again - Lazarus instance is running but not responding.

New information: when I take it to my Windows machine, I have a notice about exception class: EReadRerror- Unknown property: "Design TimePPI".  And Assembler window is shown. Debugging can be stopped on Windows (unlike on Mac). But it helps not even I put break on first line on form activate event. The error come prior..

Any help would be highly appreciated.

Thank you very much

Hi
Are the SVN version of lazarus on MAC and PC the same.

I suspect you have different SVN revisions running; which is causing the DPI error.
The way I got rid of the error when I updated to later SVN Release was to edit the lfm file of each form of project with a text editor and remove the line DESIGN TIMEDP from the file; it is in the first section of the fie; so no scrolling or hunting should be required. Then save the file, and then open your project with the latest SVN release of lazarus.
Development Installation Lazarus 1.3, FPC 2.7.1,Windows 7/8 32/64, OSX, *nix

Test Environment Lazarus & FPC Trunk on Windows and OSX (Cocoa Mainly on OSX). Testing also Crosscompile windows to OSX.. 
Any posts made from 2015 will be based on Lazarus Trunk.

yes, you are quite right, Josh, thank you very much for reply. But mystery is, that it started after some time on quite new Lazarus (1.7/3.1.1/53629M) instance on Mac. Nothing changed in Lazarus installation and suddenly it happened on Mac. I have only one Lazarus on Mac and no changes for two weeks.  And no message, nothing - it stopped working.

I moved it to PC and there on older Lazarus (1.6.2/3.0.0/53354) I got a message. There I removed those properties and it started working again.


But on Mac I changed nothing, the line is still here
DesignTimePPI = 72

and Lazarus started working there too. Suddenly. I can not be sure what was a problem, I have no message on Mac.

And by the way when I tried Lazlogger, which is working on PC,  I was not successful, maybe is the change in parameters to
--debug-log=/Users/jiricvrk/lazlog.txt
not enough..

Would it be better in such case to run app from terminal, could I get some messages there?


Now  I can work  again, but I am not sure when It will happen again. And without a PC a have no feedback to see.
