gdkpixbug-.2.42.6 meson setup fails: Dependency glib-2.0 found 2.7.0 but need: '>= 2.56.0'
 
I am building gdk-pixbuf with the meson system that is packaged in the tarball.

The software environment is a headless, embedded, QNAP-designed Debian-based Gnu/Linux distro based on kernel 4.14.24.

The key constraint in this environment is that there is no package manager, and the dependencies etc needed to build and install programs must be installed by hand using the Entware system. Basically, a parallel environment is created in /opt/Entware.


Please accept that this is the environment I have to work in to get the functionality I need on my NAS. it's just a lot more painful than in other distros.I have installed most of the standard functionality of a standard linux distro, including core-utils, pkg-config, cmake, gawk, gcc, glib2,ldconfig, libacl, and more.

My current issue is building gdk-pixbuf-2.42.6. For this build, glib-2 is a dependency and I have glib-2.7.0 installed.

Meson correctly identifies the version number I have, but still fails with the error:
Code:
Dependency glib-2.0 found: NO found 2.7.0 but need: '>= 2.56.0'
What is it looking for that it is not finding?

Here is the log from the meson.build.
The section in red seems to show that it found glib-2.0 OK.
then at the end, it decides that it can't and goes off to see if it can through CMake.

I don't understand how to fix this.
Expert help would be much appreciated.

You have 2.7 it needs 2.56 or greater. While the number 2.7 is greater than the number 2.56, the Version 2.7 is lower than version 2.56. There is no explicit zero padding in the minor version number.

Thank you for your help.
This seems quite bizarre. What is the actual version number of the the so-called version 2.7 that is installed and how can I tell that is is actually earlier than 2.56?

I'm having problems installing the current version of glib-2 (2.96), please see my question:

https://www.linuxquestions.org/quest...ls-4175708584/

Any thoughts you might have about this issue would be very much appreciated.

It is the same system used for the vast majority of software. What versioning system do you use for your software?

2.7.0

See for example https://semver.org/ or perhaps wikipedia.

I suggest you try LFS.
