[SOLVED] Application does not start from IDE
« on: July 15, 2020, 11:57:46 am »
With Lazarus 2.0.10 the IDE command "Start/Start without debugger" does not work, there is an error message telling me "Cannot start   cannot start application <apppath and -name> (s. picture). Starting with debugger does everything as expected. Starting the app from Finder works as well.

I lodged a bug report fo this issue a little while ago. See https://bugs.freepascal.org/view.php?id=36780

The issue occurs when the Lazarus IDE has been compiled with FPC 3.2.0 (release) or 3.3.1 (trunk). I have a trivial (brute force) patch to fix the issue. See the Wiki Lazarus IDE - Unable to "run without debugging".

Thank you for your hints.
I found main.pp in /library/Lazarus/IDE and made the modification as described.
Recompile of Lazarus seems to be done, but I don't find any new executable.
Restarting Lazarus, trying to start without debugger, same problem as before.
It seems, that the new executable is not active or anything else.

You need to REBUILD lazarus.


TOOLS -=> Build Lazarus with Profile: Normal.


That should do the trick

Do you have write access to the directory that contains the Lazarus source code?

When the Lazarus directory is write protected, as in Unix systems, the IDE builds its new executable into a sub folder of the primary config path, for example ~/.lazarus/bin/. You can see the primary config path in View / IDE internals / About IDE.

Once you run startlazarus, it searches and starts the newest lazarus executable. Initially it starts the original from the installation directory. After Lazarus has rebuilt itself, startlazarus starts the newly built version.

Thanks a lot, Trev.

since Installation of Lazarus needs admin permissions and my macOS standard user does not have any admin permission, the new executable was found in .../.lazarus/bin. Just moved (with macOS terminal) the rebuilt lazarus file into the correct folder /library/lazarus, and hi, it worked.
BTW, it is interesting that the rebuilt binary is nearly as twice as large (67 MB) as the original one (38 MB).

No worries! Glad to have been of help.

PS. Size - may have something to do with your debug settings when rebuilding the IDE.
