March 1, 2012 • Help wanted! Click on the little flags under LXR logo (only from the start page).

February 5, 2012 • Beta User's Manual for release 0.11 uploaded. Available through the "beta" documentation link on this page.

January 27, 2012 • Demo upgraded to use 0.11-beta version. Default view is still 0.10. To display 0.11-beta, select from the menu.
This demo offers two trees: LXR is the traditional way of displaying plain files (releases 0.9.8 to 0.10, plus 0.11-beta, are loaded); LXR/CVS shows everything from LXR debut in CVS snapshot taken on January 26th, 2012.

December 28, 2011 • Release 0.10 available for download. Users are encouraged to update to this version since it corrects many bugs, offers more langage support and brings new features.
Have a look at the demo.

December 27, 2011 • Demo operational again!
Malfunction was caused a) by a syntax problem due to the old version of SourceForge's Perl interpreter, b) by a bug related to "search" script.
NOTE: click on the "Change" button after you select another version in the drop-down menu for the change to take effect.
Have a good navigation!

December 27, 2011 • Demo LXR has been switched to 0.10, but SourceForge configuration is a bit peculiar (old Perl interpreter, missing system free-text search engine, security oriented directory structure, launching of time-consuming tools forbidden in Web mode, ...). Consequently, this demo is a bit unstable and buggy: for instance, you cannot change the displayed file version from the links unless you fiddle manually the URL (remove the %24 sequence).
The problem is under close investigation.

December 26, 2011 • Release 0.10 is available in the demo for browsing. However genxref has not been run against it, consequently you have no croos-references (temporarily).

December 18, 2011 • The advanced configuration topic now reflects the features of the upcoming 0.10 release. Some are not applicable to current 0.9.10.

October 9, 2011 • Important notice about unofficial copies of this site in the "typographical conventions" page.

October 3, 2011 • Added clarification on multi-tree configuration.

July 23, 2011 • New troubleshooting page; please give feed back to improve it.

June 25, 2011 • Demo operational again!

June 24, 2011 • Clarification in installation, presentation enhancement.

June 12, 2011 • Release 0.9.10 available for download. Users are encouraged to update to this version since it corrects a serious bug.

May 29, 2011 • Release 0.9.10 will be issued before mid-June to correct bug 3278970 causing out-of-sync conditions in strings.
No other feature announced for 0.10 should be considered operational.

April 4, 2011 • LXR browsing demonstration on the LXR tree itself now possible!
Get a taste of the buttons-and-menus interface.
Also, alpha version of 0.9.10 manual available.

Translation in progress! Missing pages will be displayed in English.

介绍

LXR 是一个通用的源码索引和交叉引用工具。它通过基于 web 的视图提供了代码浏览、符号定义查询、标识符引用查询的功能。您可以使用 LXR 浏览多种语言的源码。

LXR 的意思是 “Linux Cross-Referencer”。它被设计的很通用，您不仅可以用它浏览 Linux 内核，也可以浏览各种工程项目。

LX R基于“常规”的 web 技术构建（这意味它输出的页面是常规的 HTML)，这样您就可以选择各种浏览器作为显示客户端。为了将系统依赖降到最低，LXR 的设计避免使用 Java 或其它的客户端脚本语言。

人们经常问起 LXR 和 LXRng 的区别 (LXRng 参见 http://lxr.linux.no)。 LXRng 是 LXR 的一个试验性分支，它的目的是尝试其它一些技术的在 LXR 上的应用。LXRng 基于 AJAX 和其它一些 CPAN 包构建。它使用了大量客户端脚本技术，计算载荷也得以在服务器和客户端之间分配。

注意！

看起来在2014年上半年 lxr.linux.no在没有通知的情况下关闭了。这个站点有无备份不得而知。

更新：好消息，2016年中旬，这个站点又回来了！

对于服务器架设来说，任何能够支持 CGI 脚本的 web 服务器都能够很好地满足需求。

在项目开发中，LXR 可以作为帮助您“统观全局”的工具。它也可以作为您从头开始学习源码的利器。使用 LXR 可以大大降低学习曲线的坡度。

安装指南

按部就班的 LXR 安装指南

如果您将 LXR 升级到 2.2 版本的同时不希望重新对代码树进行索引，请阅读这个指南。但我们还是建议您用重新安装的方法升级 LXR，那样更加可靠。

较早前版本（已废弃）请参见以下链接：

0.11
0.9.x 和 0.10.x
对于更早的版本请阅读和源码包一起发行的 INSTALL 文件

高级配置

Troubleshooting

安装遇到问题，请参考这里。

示例：用 LXR 建立 LXR 自身的源码树的交叉索引

Safety procedures on SourceForge no longer allow to provide demos in web service.

本示例建立从 0.9.8 版本到最新版本的索引，可以用于展示和比较不同版本源码的差异。本示例将向您展示两种不同的建立索引树的形式：

经典的普通文件树用来展示几个选取出来的源码版本；
CVS 仓库树用来展示全部的代码版本；
由于 SourceForge 的限制，本例只是一个版本库快照。快照的保存日期在根路径给出。
LXR 的源码切换到 Git 管理之后，本示例就不再更新了。

注记:

SourceForge 的 Perl 升级到5.10后（2014年5月），标准 LXR 引擎又可以重新使用了。
SourceForge的 MySQl 数据库的用户权限阻碍了在源码树索引过程中所需的完整性检查。所以我们用 SQLite 进行了替代
SourceForge 有复杂的配置策略，在服务器上移除了一些支持工具以提高安全性。因此 LXR 的一些特性不能如期正常工作 (例如 CVS模式下文件注记 (annotations) 显示)
由于同样原因，本示例也无法引用 Git 版本仓库
