'Can't find unit UApp' error tying to build in ubuntu 24.04

[iav]

ubuntu 24.04, installed fpc from system repository. Trying to build:

# make build
mkdir -p ./bin
mkdir -p ./output
fpc -FE./bin -FU./output -Ci -Cr -Co -Ct -CR -Xs -Sa -O2 ./src/tparted.lpr

What's wrong?
where to get UApp?

UApp is part of the Unicode version of the Free Vision framework. It has been in beta since version 3.1.1 (currently at 3.3.1), but I don't think it is included in the current released version of the Free Pascal Compiler. If you don't mind experimenting you can use fpcupdeluxe to setup a beta version of the compiler.

Edit: Have you tried to install fp-units-fv-3.2.2 package? Looks like Ubuntu split Free Pascal into multiple smaller packages.

[iav]

Now I install fp-units-fv-3.2.2, but nothing changed.
I see file /usr/lib/aarch64-linux-gnu/fpc/3.2.2/units/aarch64-linux/fv/app.ppu is present.
Maybe any env var should be added?

[iav]

Or is UApp a different build of libraries, which are different files, and they just don't provided in Ubuntu?

[iav]

I see fpc-source-3.2.2: /usr/share/fpcsrc/3.2.2/packages/fv/src/app.pas.
Maybe, it's possible to tell make build unicode version of module from source?

[iav]

ok, I try to build non-unicode version.
I do change:

diff --git a/src/configs.inc b/src/configs.inc

You can build the beta version (trunk - 3.3.1) of the compiler using fpupdeluxe. It is basically a 1-click job:

Of course you need to symlink the result binary. Remember to remove the current 3.2.2 from the system before doing so:

  sudo cd /usr/local/bin/
  sudo ln -s /where-Set InstallDir-points-to/fpc/bin/x86_64-linux/fpc.sh fpc

ok, I try to build non-unicode version.

There is no non-Unicode version of tparted. At one point I decided to discontinue it because the differences between the two versions were too significant. The non-Unicode version of Free Vision uses an extremely outdated string type from the DOS era, with a fixed length of 255 characters.

[iav]

My goal was to get a script for building a package for debian and ubuntu build systems that can be used in popular packaging systems. So I can use fpc from the distribution authors, I can try to rebuild libraries from the source texts supplied in the distribution. But having fpupdeluxe among the build dependencies, unfortunately, is not.

[Kagamma]

That's unfortunate. If that's the case then we have to wait for the FPC team to include it in the next major release (likely 3.4.0). The upcoming minor release does not include the Unicode version.

[Kagamma]

Hi! I just want to inform you that in latest commit the app officially supports the ShortString version of Free Vision framework. So it should be able to build using the fpc version from Debian/Ubuntu repo.

[iav]

Great news!
I'll try to do it as soon as I have time!

[iav]

Да, теперь это работает.
Великолепно!
