How to find where older version of GLIB has been installed?

Question

I am trying to install atk-2.4.0 and I get the error:

 'pkg-config --modversion glib-2.0' returned 2.32.3, but GLIB (2.26.1)
*** was found!

I also tried updating PKG_CONFIG_PATH to include the path of glib-2.0.pc but still same error appears. Could anyone help me how to find where 2.26.1 was installed I am relatively new to Ununtu? Thanks.

What is the output of this operation - find /usr/ -iname "*glib*.pc"? And dpkg -l libglib2.0-dev? – Cupping

dpkg -l libglib2.0-dev Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii libglib2.0-dev 2.26.1-0ubuntu Development files for the GLib library – Marnie

@Cupping find /usr/ -iname "*glib*.pc" /usr/local/lib/pkgconfig/glib-2.0.pc /usr/lib/pkgconfig/glib-sharp-2.0.pc /usr/lib/pkgconfig/glib-2.0.pc – Marnie

So you have glib version 2.26.1 installed through Ubuntu repositories but also you have installed version 2.32.2 from source (this is a guess based on the path being /usr/local/ which is the default configured path. So which version of glib do you need to use? What have you set PKG_CONFIG_PATH & LD_LIBRARY_PATH as? – Cupping

@Cupping they were both empty, I guess I didn't set them correctly last time. But this time I set PKG_CONFIG_PATH to /usr/local/lib/pkgconfig and wasn't sure what to set LD_LIBRARY_PATH to. I am still getting the same error message. – Marnie

If you need version 2.32.2 set PKG_CONFIG_PATH to /usr/local/lib/pkgconfig (which you have) & LD_LIBRARY_PATH to /usr/local/lib/ – Cupping

@Cupping Awesome, thank you. Do you know some good book or some other resource that I could use to better understand the kernel structure and the installation process, I have good programming foundation but know nothing about the kernel. By the way you could post your comment as an answer and I'll accept it. Thanks again for the help. – Marnie

This SO post - https://mcmap.net/q/1633168/-linux-kernel-development-closed might give you pointers regarding kernel development, I am sorry but I am not qualified enough to suggest something on my own :) – Cupping

Answer 1

Posting comments as response:
From find /usr/ -iname "*glib*.pc" it is found that there .pc file related to glib is available in /usr/lib/pkgconfig & /usr/local/lib/pkgconfig. Checking the system package management it appears that version 2.26.1 is installed from the repositories. The path for installation of glib from repositories is generally /usr/lib (This may vary a bit in case of 64 bit systems wherein there are different folders for 32 bit & 64 bit libraries). Thus it appears that glib also has been installed from source (guessing by installation path /usr/local/lib) which of version 2.32.2. If you need version 2.32.2 set PKG_CONFIG_PATH to /usr/local/lib/pkgconfig & LD_LIBRARY_PATH to /usr/local/lib/
Hope this helps!

You have to synchronize you PKG_CONFIG_PATH and LD_LIBRARY_PATH environment variables. Assuming that your prefix is /usr/local the followings should be set:

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
LD_LIBRARY_PATH=/usr/local/lib

You may also need to set other variables to compile glib dependent softwares:

ACLOCAL_PATH=/usr/local/share/aclocal/
PATH=/usr/local/bin:$PATH
