Like it says

 has anyone tried 32 bit laz apps on ReactOS ?

[Bart]

I tried, but I could not even get the VM with ReactOS to start up.

I tried ReactOS time ago in a VM on Linux and worked.  I even tryed Lazarus (0.9.something) and worked, compiling small programs.  Didn't try anything big.

May be it's time to try it again.  Thanks for the remind.

I couldn't on the real hardware but with by VirtualBox , two of mine software worked in it.

If someone tried on real hardware I would like to get them experience.

But main point is wine , if your software work with wine probably works in reactos.

Also you can install lazarus from reactos too.

Yesterday I tried to install ReactOS on actual hardware: Intel Celeron 700 Mhz, 512 MB Ram.
If I set the installation partion to be BTRFS (?) the computer just hangs after reboot.
The BTRFS partition cannot be read by a recent live Linux CD.

If I install on FAT32, it cannot find the bootloader.
I wiped the disk completely with FDISK (had to boot the machine from a floppy, that's nostalgia kicking in for you). Created a new primary partition (FAT32), made sure that MBR was OK (FDISK /MBR).
Retried installing ReactOS on the FAT partition: still cannot find freeldr.sys.

I gave up and installed HAIKU on the machine.
It runs, it can mount my secondary FAT32 partition, it can play music (old Windows WAV-files).

Now waiting for the 32-bit HAIKU compiler.

I am not familiar with the current status of ReactOs, but about two years ago it worked perfectly fine with Lazarus and FPC.
It even worked with KOL/MCK.
That is in all three their at that point current status and run from a USB stick.

Well, tried to install ReactOS (0.4.10) on a VirtualBox VM (host: Win10-64).
It booted, did configuration, asked to reboot, loaded and then immediately gave me a BSOD, even in safe mode.

I tried that with my multiuser dp-application with built in pdf-viewer.

It is working very good and works faster (than on windows), but it has still some bugs like toolbar images are flipped. I am not sure but belive printing is still missing.

First of all, ReactOS is still in alpha stage. Although some of us can handle its limitations, you should not use it in production.
Newest version is 0.4.10 according to www.reactos.org.

Recently, I have tested again ReactOS 0.4.10 only on VirtualBox 6.0.0.

I have run with success some old Delphi 7 applications on ReactOS 0.4.10 connection to remote Firebird 2.5.8 server.

I was not able to install any recent version of Lazarus:
- Lazarus 1.6.4 and FPC 3.0.2
- Lazarus 1.8.2 and FPC 3.0.4 (ReactOS Applications Manager official version)
- Lazarus 1.8.4 and FPC 3.0.4
- Lazarus 2.0.0 RC 3 and FPC 3.0.4
- Lazarus 2.0.0 RC 3 and FPC 3.2.0 beta

I could run some simple Lazarus 1.8.4 and FPC 3.0.4 applications. See attached images.

I could install, but not use locally Firebird 2.5.8.
FlameRobin and Lazarus 1.8.4 simple applications worked against remote Firebird 2.5 databases.

I had problems dealing with images and printing on those simple Lazarus applications, so they need more testing and investigating.

Not exactly.
I have tested some Lazarus 1.8.4 applications on Wine and they worked correctly, but they had some flaws on ReactOS.

I couldn't on the real hardware but with by VirtualBox , two of mine software worked in it.
Also you can install lazarus from reactos too.

I have tried really hard, but could not manage to install any recent version of Lazarus.
The Lazarus installer freezes the ReactOS on virtual machine, then I have to reboot it.

I had the same impression.  ReactOS runs much faster than Windows XP, Windows 7 and Windows 10 on VirtualBox 6.0.0.

I am not sure but belive printing is still missing.

Albeit tested, I was not able to print either.

Summing up.

Main focus of ReactOS is to keep working applications and tools developers need to keep building ReactOS itself such as C and C++ tools, Firefox, Thunderbird, Notepad++, Adobe Reader, 7zip, VLC Media Player, etc.
Programming IDEs such as Lazarus are not priority.
Lazarus has already worked on ReactOS, but due to a regression it is not working anymore. There are already people trying to solve those issues.

FAT, FAT32 and FATX work, but they are slow.
BTRFS is the fastest and best bet for now.
There is no NTFS so far.
Nothing that needs a USB port works, including keyboard, mouse, external HD, flash drive, etc.
Printers still don't work.

Now waiting for the 32-bit HAIKU compiler.

Yes, and my comments are on Mantis (sorry, can't give a number from where I currently am).

Bottom line is that (working from memory) unpacking Lazarus goes too long between forced syncs, which triggers a watchdog. I was able to install it by starting off on FAT and then copying to BTRFS (or something like that).

IMO- and it hurts to say this-  BTRFS even on Linux is more trouble than it's worth.
