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

Please tell me how can I fix my problem.

Thank you.

安装libxtst-dev软件包，您就可以编译Chromium源代码了。

Answer 2

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.
