How to find X11/extensions/XTest.h

Question

I am using ubuntu 10.10, and when i compile chromium, it said remoting/host/event_executor_linux.cc:9: fatal error: X11/extensions/XTest.h: No such file or directory

But i have already installed libx11-dev:

$ sudo apt-get install  libx11-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libx11-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Please tell me how can I fix my problem.

Thank you.

libX11 is the core X protocol library - anything under X11/extensions is generally one of the extension libraries. — alanc, Feb 22 '11 at 02:27

Install libxtst-dev package and you'll be able to compile Chromium sources.

Note: the package name might not be exactly the same. On the Fedora 16 I had to do: `sudo yum install libXtst-devel` – Hamish Grubijan Nov 19 '12 at 23:31

This helps compile keepassx, as well. – earthmeLon Feb 27 '13 at 22:30

I still had issues in finding this header file in RHEL6.2. I had to do "sudo yum install libXi-devel" to fix it. Got the hint from here: https://code.google.com/p/box2d/issues/detail?id=127 – nom-mon-ir Nov 19 '13 at 03:29
Also helped with compiling [NEURON](https://neuron.yale.edu/neuron/) on Ubuntu 19.04. – TheBamf Feb 19 '20 at 13:49
npm module `robotjs` also requires this. Thanks. – Bharat D Bhadresha Jul 28 '23 at 17:35

To find to which package your include file (X11/extensions/XTest.h) belong to, install apt-file and search for it, example:

$ sudo apt-get install apt-file
$ sudo apt-file update
$ apt-file search "X11/extensions/XTest.h"
libxtst-dev: /usr/include/X11/extensions/XTest.h

Once you've the package name, install via:

sudo apt-get install libxtst-dev

This method is especially useful when there are more similar dependencies like that, so you don't have to guess.
