[fernandog]

worked. thanks.
Why needed to manually installed those?

[lazka]

They are not Python packages, and there is as far as I know, no standard way to deal with those.

But maybe we can print a nicer error message if one is on a Debian based system.

@vinaysimhabn I haven't used snapcraft yet, but have you tried adding "pycairo" to "python-packages" list?

[vinaysimhabn]

i have tried pycairo to python-packages, even that also fails saying "ImportError: No module named 'cairo'.

[vinaysimhabn]

hi,
earlier i was building in x86, it was failing for pycairo and pygobject.
now i am building in arm64, i am able to build the pycairo, but not able to build the pygobject. please suggest

This means you are missing "gir1.2-glib-2.0"

Please help me with this

[cleebp]

For Mac users simply brew install cairo before pip installing and it should work fine.

[ianfowler]

@cleebp pip installing after a successful brew install resulted in the following:

ERROR: Could not find a version that satisfies the requirement cairo (from versions: none)
ERROR: No matching distribution found for cairo

Did you mean pip installing something else?

[peratik]

sudo apt install libcairo2-dev

[petervandenabeele]

As suggested above, is there any systematic way of doing:

• if on Debian/Ubuntu or on Mac
• test that required dev packages are installed
• if not => print out a clear hint with

# the build will probably fail, you probably need to execute
sudo apt install libcairo2-dev libgirepository1.0-dev

or

# the build will probably fail, you probably need to execute
brew install cairo ...

Adding this, would make the installation a lot more user friendly :-)

Anyway, works for me now, thanks for everything :-D

[lazka]

I've opened #175

[Saamy88]

What about for CentOS7?

[tnt4brain]

What about for CentOS7?
Looks like you should install three packages (on a fresh CentOS box):

1. python-devel
2. gobject-introspection-devel
3. cairo-gobject-devel

These three packages will bring you all the stuff you need, so "pip install PyGObject" could proceed without glithces.

$ sudo apt-get update
$ sudo apt-get install build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev

[bitnom]

use direnv or just add to your profile/rc:

export PKG_CONFIG_PATH="/usr/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH"

[SakurajimaMaii]

sudo apt install libcairo2-dev

Useful solution

[AvinandanPal25]

"sudo apt install libcairo2-dev" seemed to be the answer.

But can anyone guide me on how to do it on windows cmd.

I'm getting this error if I run the above command.
sudo : The term 'sudo' is not recognized as the name of a cmdlet, function, script file, or operable program.
I really need the solution. Thank you.

[danyeaw]

@AvinandanPal25 You can either build cairo and pycairo using gvsbuild or install msys2 and install the right packages (mingw-w64-x86_64-cairo, mingw-w64-x86_64-python-pip, etc)

[stories2]

export PKG_CONFIG_PATH="/usr/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH"

It works for me. Ty

Hello,
I installed fresh LXC contained with Debian 12 on Proxmox 8, installed lxqt and xrdp:

apt install lxqt-core xrdp
adduser xrdp ssl-cert
reboot

I have added a user and can successfully login as my user using remote desktop client. Everything works except lxqt-globalkeysd, when I launch it manually in the terminal app, I get the following error:

$ lxqt-globalkeysd

[stuaxo]

If you use homebrew to install cairo, then when you use pycairo it should probably be from python installed by homebrew as well.
