[SOLVED] Compile Krita

vmelkon · 05-15-2021, 09:34 AM

Allo all,
I am trying to compile Krita.

I followed the instructions at
https://docs.krita.org/en/untranslat...ing_krita.html

I ran
cmake ../krita \
-DCMAKE_INSTALL_PREFIX=$HOME/kritadev/install \
-DCMAKE_BUILD_TYPE=Debug \
-DKRITA_DEVS=ON

and I get

Code:

-- Found KF5Config: /usr/lib/x86_64-linux-gnu/cmake/KF5Config/KF5ConfigConfig.cmake (found version "5.74.0") 
-- Could NOT find KF5WidgetsAddons (missing: KF5WidgetsAddons_DIR)
-- Could NOT find KF5WidgetsAddons: found neither KF5WidgetsAddonsConfig.cmake nor kf5widgetsaddons-config.cmake 
-- Could NOT find KF5Completion (missing: KF5Completion_DIR)
-- Could NOT find KF5Completion: found neither KF5CompletionConfig.cmake nor kf5completion-config.cmake 
-- Found KF5CoreAddons: /usr/lib/x86_64-linux-gnu/cmake/KF5CoreAddons/KF5CoreAddonsConfig.cmake (found version "5.74.0")

What is that?

If you ar running any version of *Buntu (or Manjaro, or Fedora, or Debian, or ...) then Krita i in oneof your repositories and you should not be compiling it from source. Why can you not using your package manager? What version//release of what distribution are you running?

shruggy · 05-15-2021, 11:01 AM

Have you installed all the build dependencies listed there? Like libkf5widgetsaddons-dev and libkf5completion-dev?

Even if you're building from source, it's much easier to rebuild from your distro sources than build from scratch. You do know about apt-get source and apt-get build-dep, don't you?

I am running Kubuntu 20.10. Yes, Krita is in Discover.
But the goal here is to see how to compile Krita and to modify something in Krita and to figure out where to place the executable.

Getting all ~69 build dependencies installed :

Code:

sudo apt-get build-dep krita

In general, the build process install has install locations specified. You can change them, and if you code enough to modify the package you should already know hoe to find and change the install base.

Best of luck, I think with the install of the prerequisites for the build you are on the right track.

It says
jake@john-desktop90:~$ sudo apt-get build-dep krita
[sudo] password for jake:
Reading package lists... Done
E: Unable to find a source package for krita

shruggy · 06-10-2021, 12:49 AM

Do you have deb-src lines enabled in your /etc/apt/sources.list?

vmelkon · 06-10-2021, 07:22 PM

Now I get

Code:

-- Krita version: 5.0.0-prealpha
-- Branding selected: Next
-- Python system site-packages directory: /usr/lib/python3/dist-packages
Installing in /home/jake/kritadev/install. Run /home/jake/kritadev/build/prefix.sh to set the environment for krita.
-- Could NOT find ZLIB (missing: ZLIB_INCLUDE_DIR) 
CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
  Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-3.16/Modules/FindPNG.cmake:146 (find_package_handle_standard_args)
  CMakeLists.txt:620 (find_package)

but I already ran
sudo apt install zlib1g-dev
sudo apt install libpng-dev

shruggy · 06-11-2021, 12:49 AM

Well, the problem is only with finding ZLib. CMake fails to find libpng because of the first error. From /usr/share/cmake-3.16/Modules.FindPNG.cmake:

Quote:

The following variables may also be set, for backwards compatibility:

``PNG_LIBRARY``
where to find the PNG library.
``PNG_INCLUDE_DIR``
where to find the PNG headers (same as PNG_INCLUDE_DIRS)

Since PNG depends on the ZLib compression library, none of the above
will be defined unless ZLib can be found.

I guess CMakeLists.txt of Krita changed recently, and now breaks builds with CMake 3.16.

Required deb-src lines in /etc/apt/sources.list lines are ....

Code:

deb-src http://archive.ubuntu.com/ubuntu/ groovy main universe

deb-src http://archive.ubuntu.com/ubuntu/ groovy-updates main universe

... Then there shouldn't be any missing 'build prerequisites' :

Code:

sudo apt update
sudo apt build-dep krita

cd krita/ && mkdir build && cd build/
cmake ..

.. and the cmake configuration is perfect, no errors : Ubuntu 20.04 .
EDIT : Ubuntu 20.04
$ make
[100%] Linking CXX executable krita
[100%] Built target krita
EDIT 1:
Krita 5.0.0-prealpha https://github.com/KDE/krita configures OK with cmake in Ubuntu 20.10 :
--Build files have been written to ~/tmp/krita/build

EDIT 2:
$ sudo apt install libmypaint-dev (One of the optional build packages for 5.0.0).
Your cmake options : $ cmake -DCMAKE_BUILD_TYPE=Debug -DKRITA_DEVS=ON ../
Also OK. --Build files have been written to ~/tmp/krita/build

Compiling with "BUILD_TYPE=Debug" will require 9-10 GB build space, and take some hours to do.

Krita 5.0.0-prealpha, Ubuntu 20.10 :

Code:

$ make
[100%] Linking CXX executable krita
[100%] Built target krita

Holy smokes!
My krtia folder that I downloaded has 11,250 fiels and 810 folders and it is 932 MB. People typed that much code?

But are those lines
deb-src http://archive.ubuntu.com/ubuntu/ groovy main universe
deb-src http://archive.ubuntu.com/ubuntu/ groovy-updates main universe

suppose to exist in that sources.list file or do I have to type them in?
I don't have those lines. Mine looks like

Code:

# deb cdrom:[Kubuntu 20.10 _Groovy Gorilla_ - Release amd64 (20201022)]/ groovy main multiverse restricted universe

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to

## distribution.

## Uncomment the following two lines to add software from Canonical's

deb http://archive.canonical.com/ubuntu groovy partner

deb http://security.ubuntu.com/ubuntu groovy-security main restricted
deb-src http://security.ubuntu.com/ubuntu groovy-security multiverse restricted universe main

# deb-src http://security.ubuntu.com/ubuntu groovy-security universe
deb http://security.ubuntu.com/ubuntu groovy-security multiverse
# deb-src http://security.ubuntu.com/ubuntu groovy-security multiverse

So I added these lines at the bottom
#I added these for krita
deb-src http://archive.ubuntu.com/ubuntu groovy main universe
deb-src http://archive.ubuntu.com/ubuntu groovy-updates main universe

and ran
sudo apt-get build-dep krita
and I guess it did nothing and it says
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

These are equivalent as they include both main and universe components:

Code:

deb-src http://ca.archive.ubuntu.com/ubuntu/ groovy multiverse restricted universe main
[...]
deb-src http://ca.archive.ubuntu.com/ubuntu/ groovy-updates multiverse restricted universe main
