FPC and Lazarus sources were moved from the SVN server to GitLab. They don't exist in SVN any more. I see Alextpp removed the incorrect SVN references from that page. Thanks.

All good then. By the way, the svn instructions showed how to use svn to get code from github, not the old svn repo. Personally, I sure will not miss it either way.

Hi all, thank you for the really good job. I just add a comment, the TVPlanIt components does not compile with the latest Lazarus release, the code ( VpXBase.pas ) still uses LazUTF8Classes and TFileStreamUTF8 classes now deprecated.

The DEB packages on Sourceforge had the wrong version.
They have been replaced.

Thanks all of you who replied and commented and helped fix that issue. 
The 3.0 is finally installed and seems to run nicely in one of my virtual machines.

I haven't yet done any project in 3.0 except for a Hello World but will use the 3.0 from now on

In case any Linux user wants to try my older software made on Lazarus 2.X dowloads available on my site.
Mainly simple games and logic puzzles. Very modest system requirements. Runs well in virtual machines.

For example a knight logic puzzle.

I just add a comment, the TVPlanIt components does not compile with the latest Lazarus release, the code ( VpXBase.pas ) still uses LazUTF8Classes and TFileStreamUTF8 classes now deprecated.

Just installed TVPlanIt into a fresh installation of Lazv3.0 in Windows 11 (both 32 and 64 versions), and there was no issue. Did you install over a previous installation of TVPlanIt? Maybe a compiled unit is out-of-date and not detected as such. Try a clean recompilation of the IDE ("Tools" > "Configure Build Lazarus" > check "Clean all" and "Switch after building to automatically" > "Build").

Or, since you mention VpXBase: the unit LazUTF8Classes was removed from the development version here in mind-June, and then was release for OPM as v1.8.2. -> Reinstall from OPM.

OK many thanks,

I ran a new fresh installation of Lazarus and I downloaded TvPlanint from the On line package manager.

In any case I will check all the actions once again.

I installed Lazarus 3.0 for macOS from scratch,
but I have a problem rebuilding the IDE, I get the error "can't find unit DateTimePicker used by DateTimeCtrls".

How do I correct it?

Another thing I noticed on macOS is that the title says "Lazarus IDE v3.0 r", I guess the "r" shouldn't be in this version.

Awesome Job!

Just wanted to say... Thank you very much Lazarus Team !!!

I am using Lazarus 3.0 on MacOS (Monterey) without any difficulties. I suggest you try downloading the 3.0 source and building that. If you can build a Lazarus project, you can build Lazarus itself, its easy.

Many thanks!

On Linux-i386, it is impossible to install the DEB package. It stucks at

"half-installed" means, I think, files physically in place but application not yet configured.

When you uninstalled 2.2.6, it will have removed all the Lazarus components in read-only diskspace but not your local configuration. Is it possible that the new install of 3.0 is trying to update and use that 2.2.6 config ?  As I understand it, the answer is 'no' (that happens when you start lazarus) but you are seeing some strange things.

You have not, at any time, run lazarus as root have you ? I sure hope not.

I'd be looking in ~/.lazarus to see if there are any root owned files in there.  But a far cleaner and safer approach would be to completely remove ~/.lazarus  and  try again, perhaps with -

Code: [Select]

sudo apt install --reinstall lazarus-project
As usual, my real advice is to just install Lazarus from source, Lazarus, by its nature, is not happy up in read-only space. The devs have done a wonderful job of "behind the scenes" stuff to make it appear it is comfortable but it is NOT.

The installer does not at all touches the config files. They are updated when the new Lazarus is started for the first time. But i've removed them anyway, so this is not the case.

You have not, at any time, run lazarus as root have you ? I sure hope not.

I'd be looking in ~/.lazarus to see if there are any root owned files in there.

I did, i do. All the time. I only use all my machines as root. And i have never had any problems with Lazarus before. So, ~ is /root and /root/.lazarus have/had only root owned files, but since i've run the installer as root either it cannot be the problem.

But a far cleaner and safer approach would be to completely remove ~/.lazarus  and  try again, perhaps with -

Code: [Select]

sudo apt install --reinstall lazarus-project

I cannot do that. It is an old Debian Stretch, it has no lazarus-project in the repos. I always installed the latest Lazarus via the DEB packages from sf.net.

As usual, my real advice is to just install Lazarus from source, Lazarus, by its nature, is not happy up in read-only space. The devs have done a wonderful job of "behind the scenes" stuff to make it appear it is comfortable but it is NOT.

Until now i did not have to do that for Linux; the DEB packages were always working without problems.
