Can't launch Lazarus with one particular package on OSX only

[tintinux]

Hi,

I have installed Lazarus 1.0.14 on Lazarus and it works not too bad, I can compile and execute some simple applications in the EDI.

I have also made my own package (Gestinux_util) which works fine for me on several Windows and Linux Lazarus installations.

If I try to install this specific package  on Lazarus for OSX (I have only 10.6), it compiles, no error is visible when installing, but Lazarus do not launch afterwards.

After this package installation attempt, I can only launch Lazarus by executing in a terminal : /Developer/lazarus/lazarus
I see some debug messages in the terminal, but nothing looks related to the new package (I can post it if it helps, but I doubt).
This way Lazarus is running, but I have no menu and can't do much...

My only choice is to delete the new lazarus executable and restore lazarus.old ...

There is obviously someting wrong with my package, but how can I find what ?
Your ideas are welcome !

Thanks
Tintinux

I am not on Mac, so I cant comment on the issue itself.

But when running from terminal, try:

/Developer/lazarus/lazarus.app/Contents/MacOS/lazarus


Also, this may be a sym-link. Check where it points too

Hi

The path you suggest is exactly the same as in the app, i.e the normal way to run the IDE.
So, the result is the same, Lazarus crashes without message.

I suppose there is something wrong in one of my component instanciation (Create or so).
If I'm not wrong, DebugLn can't be used the debug this ?
My question was : Is there any other way to debug, except removing components creation or code lines  until it works ?

Thanks.

Hi

It took time, but  I have found the cause of the issue :

In one unit of a package I created there is in the initialization section :

Code: Pascal  [Select][+][-]

1. var i : byte; [...]  for i := 1 to DefaultFormatSettings.CurrencyDecimals do ....

This raise no error on Windows and Linux, but on OS X, after the package is successfully compiled and then installed, Lazarus can't launch anymore, without visible message.

I changed to :

Code: Pascal  [Select][+][-]

1. var i : byte; [...]  for i := 1 to 2 do ....

and the package can be installed, and Lazarus can be launched afterwards.

Has anyone heard of a similar bug, or anything to say, before I file it in the bucktracker ?

PS : now, I'm with Lazarus 1.6

Code: Pascal  [Select][+][-]

1. var i : byte; [...]  for i := 1 to DefaultFormatSettings do ....

That code doesn't tell me anything. Normally DefaultFormatSettings is a record.

Yes you are right ! 
It was DefaultFormatSettings.CurrencyDecimals
I corrected in the post.
Best regards

It was DefaultFormatSettings.CurrencyDecimals

Why are you using that in a loop? CurrencyDecimals is just the number of decimal digits that currency values should be reported to for your locale. On my system, it has a value of 2.

[tintinux]

This is to make a format string, depending on the actual value.
Yes, it is also equal to 2 in most countries...

[Phil]

You've got something else going on then. Looping through the value of CurrencyDecimals works fine on OS X too.

In any case, why aren't you just using FloatToStrF or equivalent?
