Lazarus Release Candidate 2 of 4.0

[TRon]

This files are Release candidate 2.0?

Yes, they belong to lazarus 4.0 RC2.

In fact they are the free pascal 3.2.2 compiler and its accompanied sources (that are both used by Lazarus 4.0RC2).

If you already have these installed then you could also opt for not installing these two .deb files and on first startup point Lazarus to the correct location where these are located on your system (Lazarus will ask on first startup if you do not have an already installed Lazarus. In case you already have Lazarus installed then make sure to backup your original Lazarus configuration directory)

I suppose a simple fix would be to allow negative values for the extra glyph spacing setting.

You can enter any value (even negative) into the combo box manually.

An oddity here, I was writing a small program that converted ounces to ml and getting the value from an edit field:

Edit1.Text

which is a TCaption, the auto-complete allows me to add .ToDouble and in the IDE does not complain. Complains when I try to build. Typecast to a string as string(Edit1.Text) and builds correctly. Not a big thing but ...

Please report as new issue. Thanks.

- Codetool should not suggest this, if it does not work.
- Maybe a helper for TCaption needs should be added.

I made a merge request so that the Object Inspector patch doesn't get lost in the messages.

Hi, Martin

I spent a bit of more time on 4.0rc2 than 4.0rc1, and found a bit of more issues... and make me think it's not on the 'rc' quanlity though...

About my environments:
   Slackware 15.0 x86_64 + up-to-date updates
   GTK2 and QT5 from distro
   XFCE 4.16
   FPC 3.2.2 build by myself
   Lazarus 3.2 for current proejcts

I'll try to do more testing to report or patching.

BTW: is there any info about fpc 3.2.4? will lazarus 4.0 ready for it?

I don't have insight into what the FPC team is doing. So I don't know 3.2.4 will be.

Lazarus 4 currently (afaik) works with 3.2.3, which is near identical to 3.2.4. So whenever that goes forward it should be ready.

Hi! This is not a bug, i think. Downloaded latest lazarus 4 fixes with fpcupdeluxe and i've found that i installed pack_powerpdf (0.9.16) from onlinepackagemanager, and when i try to install lazreportpdfexport (lazarus component) it gives error asking for powerpdf 0.9.17 but in package manager is only 9.16.
I've found in the source repo that there is 9.17 but still not added to online package manager.
ill try to download manually, update and try again
Thanks for the good work

downloaded 0.9.17 from the web, uninstaled prior, installed 0.9.17 with no errors and then installed lazreportpdfexport without problems. It seems that online package manager need to be updated only.
Thanks

Hello,

RC2 crashes on both of my Mac machines (1 x Intel/Monterey, 1 x Arm/Sequoia) with a segmentation fault during early startup, before the main window appears. This happens with the provided binary as well as with one built from the git source. RC1 worked fine. Should I dig deeper and/or create a ticket?

Best regards
Joerg

Best to report.

If you can catch any stacktrace (from console) then that might help.

Does it get to the setup dialog? (try with --setup ).
If yes, does it crash with/without anchor-docking / docked-form?

I can provide a full crash report from Mac OS. It looks like an endless recursion. It happens after the setup dialog, but before anything else (including the splash dialog) is shown on screen, and regardless of the IDE style. I think I already identified the problematic piece of code (because I see file/line info with my self-built binary). I'll open a ticket.

Best regards

Many thanks to the developer and supporter team from my side too!

Regenerated three of my main projects with the RC2 - no problems at all!
(Admittedly, I look more at the functional behavior of a project than at changes within the IDE).

But this makes me a bit worrying:

It may be too late. Once the release is out we will have to be more selective about which fixes can be merged for further 4.x releases. So it may be, that we can not merge the fix you require. And then you will miss out on all the new features.

Yes, i have a very unpleasant issue still occurring with the 4.0 RC2 too (and this is the only one btw ...):

Yes, it may be that you are the only person with a project

Obviously it seems so ... for this problem report, nobody replied about the contents so far.

I cannot express enough, that after, meanwhile, a couple of weeks successfully working with the proposed patch i never would like to miss it. It does not only solve the issue with the plugin. It does make the behaviour of a treeview at mousemoves much more smoother, especially of course when working with dark theme subclassings.

Do I have to prepare myself for years of manual patching?

Do I have to prepare myself for years of manual patching?

Since when do Lazarus releases (fixes) take years ?

'Years' as synonym for a long time, sorry TRon, there was absolutely no bad intention behind, i promise
