Lazarus Release 3.0

[dbannon]

.....I am trying to follow the instructions at the wiki: https://wiki.freepascal.org/Installing_Lazarus_on_Linux

...... I think I need to install some gtk libraries for it to work correctly in my debian 12 / regolith3 desktop, but which ones?

The required libraries are listed on that page were on earlier, https://wiki.freepascal.org/Installing_Lazarus_on_Linux. All the libraries themselves will probably be present but you need the -dev libraries at link time. (Hmm, wild idea, when you say "gtk libraries, you mean gtk2 don't you ?  gtk3 is not ready for prime time yet. Qt5 is good ...)

Or, a variation of Juha's suggestion, add Debian Backports to your Bullseye repo and you will get the current release.

I think my debian 12/Regolith3 is not playing nice. I am going instead to try install a QEMU VM with plain Ubuntu 22.04 and just use that for lazarus development. I did that once and it worked ok.

[dbannon]

Can I suggest you use U20.04, it has almost no SNAPs (smaller and faster) and binaries you make there will run on (almost) all OS. If you use U22.04, you get the new glibc and binaries it makes will not run on (eg) U20.04, Buster etc.

I am still running U20.04 on my day to day machine, have to update sooner or later but I keep a Virtual Box VM with an untouched U20.04 as my release build machine anyway.

Lazarus recompile virtualtrees package on linux.

So i cannot build lazarus with last deb installer.

[Thaddy]

Davo gave you already the answer, to which I might add: also on bookworm Debians like Ubuntu you should add Backports.
That will give you FPC 3.2.2 + Lazarus 3.0. And those are current releases.

Hi
Upon compiling an old project in laz 3.0 - fpc 3.3.1, I get these errors:

maskedit.pp(563,0) Error: linker: undefined reference to `LAZUTF8_$$_UTF8CODEPOINTSIZEFULL$PCHAR$$LONGINT'
and
laz2_xmlutils.pas(616,0) Error: linker: undefined reference to `LAZUTF8_$$_UTF8CODEPOINTSIZEFULL$PCHAR$$LONGINT'

Funny thing is, I don't use either 'MaskEdit' or any kind of xml...
Has anybody seen this before ...and (fingers crossed) have a solution?!?
It compiles without errors in laz 2.2.6 - fpc 3.2.2
I have required 'LazUtils' package in project inspector.
Regards Benny

You have old versions of LazUtils .ppus somewhere in your system.

Hi
@JuhaManninen: Thanks mate, That hit the 'Head on the Nail' 
I looked, before I deleted all the files in "project-dir/lib/x86_64-linux/*"
and the only files not updated were lazutf8* etc...

A few hours ago I tried to download Lazarus 3.0 using the "Download Now" button in the upper right corner at lazarus-ide.org
I got the old RC1 .deb package.
Next, I went to the https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%203.0/ page and clicked the link https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%203.0/lazarus-project_3.0.0-0_amd64.deb/download
In that case it was OK -- now I've got the correct version.

P.S. Thank you, boys and girls! You're doing a great job!

Are we already at 3.2?

download latest debian 12 iso 32bits. Installed on vm, apt updated all.
installed al prerequisites sugested on fpcupdeluxe page
then downloaded latest fpcupdeluxe 32 bit linux executable (currently 2.4.0c).
checked gitlab check, selefcted fpc 3.2.2 and stable lazarus
clicked on "install/update fpc+lazarus" button, process started and then this error again

I found a way to install Lazarus 3.4 on Debian 12 (i386):
1) Run fpcupdeluxe v2.4.0f.
2) Click the "Setup+" button.
3) Click the "Add FPC patch" button.
4) Select the “fpc-3.2.0--glibc-2.34.patch” file and click “Ok”.
5) Click the “Install/update FPC+Lazarus” button.

[dbannon]

neuro, you have dropped into a pretty old thread here.

Not wanting to sound critical but FPC 3.2.0 and Lazarus 3.4 are pretty old too.

Debian 12, Bookworm has the FPC322 compiler in its repo, easier and better to install that, download the Lazarus 4.2 source and build it.

An even better approach is to install that repo FPC322, use it to build a FPC324rc1 from source and build Lazarus 4.2 with that. And then continue to work with that FPC234rc1 ...

You are welcome to use my Lazarus build script, https://github.com/davidbannon/FPC_Laz_Install/blob/main/make-lazarus.bash if you like.

I am pretty sure that fpcupdeluxe can build and install current versions too.

Davo

Debian 12, Bookworm has the FPC322 compiler in its repo, easier and better to install that

On Debian 12 (i386) following commands do install FPC and Lazarus, however they install old version 2.2.6 of Lazarus:
sudo apt-get install fpc
sudo apt-get install lazarus

I am pretty sure that fpcupdeluxe can build and install current versions too.

The latest version fpcupdeluxe v2.4.0f. fails to build the latest “trunk” versions of FPC/Lazarus on Debian 12 (i386) throwing errors in source code.
That is the reason why I used installation of “stable” versions of FPC/Lazarus, which however needs a patch for Debian 12 (i386), which was describe in post above.

No, I suggested installing FPC322 from the repo, but building Lazarus from source. You can get Lazarus in any release, Fixes or main as source and it should build fine. I just tested 4.2 and main. And, honestly, a source build of Lazarus on Linux is far more practical that a repo supplied version.
