Debian unable to build

[BigfootN]

Hello,

I am trying to build on Debian (sid) and I am getting the following error:

Just so you know I installed the liblightdm-gobject-1-0 dependency.

Thank you very much in advance for any help.

Install this: https://packages.debian.org/sid/liblightdm-gobject-dev

[BigfootN]

Thank you for your quick response.

Unfortunately it was already installed, so it didn't really help me. I even tried to completely remove the build directory.

Just so you know this is what I get from the meson build:

Then it is this: https://packages.debian.org/sid/lightdm-vala

I don't know why that has been put in package that doesn't have gobject in the title, as that is the name of the library. But it seems to contain the files you need.

[BigfootN]

Thank you very much it works.

Just as a last question, does it mean that lightdm-gobject-* isn't necessary ?

[davidmhewitt]

Those are both necessary too.

The -dev one and the vala one is only needed to build the greeter, the non-dev one is needed to run the greeter.
