[SOLVED]glib-2.0 depends on non existant libpcre2-8

technicap · 2023-11-16 13:38:41

The problem arises whenever I'm trying to compile anything dependent on glib-2.0. it says

Package 'libpcre2-8', required by 'glib-2.0', not found

Should I install pcre2-8 if so from where because I can"t find this version of pcre2
Thanks for help in advance.

pacman -Q pcre2

Output:

pacman -Q pcre2
pcre2 10.42-2

Package 'libpcre2-8'

That package doesn't exist on archlinux, though debian/ubuntu appear to have it.

Output of pacman -Qi glib2 ?

What are you trying to compile and do you have a PKGBUILD for it ?

You are building what, and how? Post the complete build log. Any self respecting buildsystem should use pkgconf and that would logically resolve things correctly.

Output of

printenv

technicap · 2023-11-16 15:03:37

You mean the output of command used to build or what? Program uses make to build

V1del · 2023-11-16 15:08:06

yes, and again, what program? And the printenv output?

If it's literally everything and normally properly working PKGBUILDs fail then you have a some library lookup override or a non-standard PKG_CONFIG_PATH or so, libpcre2-8 is provided by the pcre2 package under /usr/lib/pkgconfig/libpcre2-8.pc and that's not resolved for you for some reason.

The /usr/lib/pkgconfig/libpcre2-8.pc doesn't exist on my system

V1del · 2023-11-16 15:12:18

then your pcre2 installation is broken, reinstall it.

technicap · 2023-11-16 15:14:38

The pcre2 only comes in version pcre2-10 not pcre2-8 which is required by glib-2.0 and this doesn't seem to exist in aur or on github page of pcre2

seth · 2023-11-16 15:42:00

And what is your (relevant) glib-2.0?

V1del wrote:

Otherwise this is going absolutely nowhere.

Also

pacman -Qkk glib2
pkgconf --path glib-2.0
pkgconf --print-requires-private glib-2.0
pkgconf --print-requires glib-2.0 # this better be empty

I was trying to install xboxdrv https://github.com/xboxdrv/xboxdrv.
It uses sCons , its difrrent program that exibits the same as the one using make above. Here's output of running as instructed on giithub page:

This is completely untrue. In fact, there is no such thing as pcre2-10.

Why not? Look at the file list at https://archlinux.org/packages/core/x86_64/pcre2/ , the package does come with that file. Are you using NoExtract in pacman.conf or something?

Maybe pacman -Qi pcre2 can shed some light on it?

The problem here is not glib2, the problem is that your pcre2 is broken. Have you reinstalled it yet like V1del told you to?

I didn't reinstall it because I did it before and it didn't fix it. I did it now and it works. Thanks form putting up with me

seth · 2023-11-16 16:30:34

pkgconf --print-requires-private glib-2.0
[nothing]

Also post your /usr/lib/pkgconfig/glib-2.0.pc

Edit: though w/ the scons errors and your ultimate solution I suspect the "[nothing]" there is false?
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
