Another day and another major update exposed an error of missing the “x11” library. Apparently, the pkg-config got corrupted for X11 library. Most of the time the error is self-explanatory, but sometimes it is too generic like:
Run-time dependency x11 found: NO (tried pkgconfig and cmake) meson.build:412:2: ERROR: Dependency "x11" not found, tried pkgconfig and cmake
The name “x11” is a part of multiple libraries:
srv ~ # pkg-config --list-all |grep x11 gdkglext-1.0 GdkGLExt - OpenGL Extension to GDK (x11 target) gdk-2.0 GDK - GTK+ Drawing Kit (x11 target) gtk+-2.0 GTK+ - GTK+ Graphical UI Library (x11 target) gdkglext-x11-1.0 GdkGLExt - OpenGL Extension to GDK (x11 target) x11-xcb X11 XCB - X Library XCB interface gdk-x11-3.0 GDK - GTK+ Drawing Kit gdk-x11-2.0 GDK - GTK+ Drawing Kit (x11 target) gtkglext-1.0 GtkGLExt - OpenGL Extension to GTK+ (x11 target) x11 X11 - X Library xkbcommon-x11 xkbcommon-x11 - XKB API common to servers and clients - X11 support scim-x11utils scim-x11utils - X11 Utilities for Smart Common Input Method platform clutter-x11-1.0 Clutter - Clutter Core Library gtk+-x11-3.0 GTK+ - GTK+ Graphical UI Library libva-x11 libva-x11 - Userspace Video Acceleration (VA) x11 interface gtkglext-x11-1.0 GtkGLExt - OpenGL Extension to GTK+ (x11 target) gtk+-x11-2.0 GTK+ - GTK+ Graphical UI Library (x11 target)
The above example is of working x11 library pkg-config. In our broken system the 10th line was missing.
To resolve the problem just emerge the “x11-libs/libX11” successfully and your pkg-config will be repaired.
If you happened to come here not using Gentoo but with the same problem, you just missed the X11 library – https://gitlab.freedesktop.org/xorg/lib/libx11.
Or you may check your pkg-config configuration file /usr/lib64/pkgconfig/x11.pc):
prefix=/usr
exec_prefix=${prefix}
libdir=/usr/lib64
includedir=${prefix}/include
xthreadlib=-lpthread
Name: X11
Description: X Library
Version: 1.6.9
Requires: xproto kbproto
Requires.private: xcb >= 1.11.1
Cflags: -I${includedir}
Libs: -L${libdir} -lX11
Libs.private: -lpthread
This is currently our pkg-config file /usr/lib64/pkgconfig/x11.pc for version 1.6.9.

As you can see there is a problem only with the 32 bit abi multilib configuration.
x11 library missing error because of corrupted x11-libs/lib* library
Trying to build the “media-sound/pulseaudio-13.0” threw the following error even we had rebuilt the x11-libs/libX11:

The 7th line is not very clear if any of the following “xcb >= 1.6 ice sm xtst” is the problem or not!
Apparently, the check for x11 in the initial emerge build phase may throw a generic error for missing x11 library if there is problem with some libraries part of this group “x11-libs/” (probably – x11-libs/lib*).
To find out more details about the error follow the advice of the emerge just read the support log file “/var/tmp/portage/media-sound/pulseaudio-13.0/work/pulseaudio-13.0-abi_x86_32.x86/config.log” (in this current example, in your case it would be different) and search for the error:

configure:24432: error: *** X11 not found
There are more details, you see the error “No package ‘xtst‘ found” and the missing pkg-config file “xtst.pc“. We have a hint to search for a library with a name “xtst” or similar. You may do it with “qlist” (part of package app-portage/portage-utils):
srv ~ # qlist -IC|grep -i xtst x11-libs/libXtst
And the library package “x11-libs/libXtst” should be rebuilt (note the “-i” for grep case insensitive search is important). Building the package pulseaudio does not fail.
