本文详细介绍如何在Ubuntu系统上安装并配置LibLAS库，包括下载源码、安装必备组件如CMake和Boost库，以及编译安装过程。最后通过一个示例验证LibLAS的功能，输出LAS文件的详细信息。

一、下载最新版liblas源码

下载地址：https://liblas.org/download.html

二、必备条件：

CMake 2.8.1+以及C/C++编译器

三、编译

1.首先，你必须已经安装1.38.0及以上版本的Boost库。没有安装的可以参考我的博客：ubuntu：安装boost库 v1.70

2.然后执行如下命令：

cd liblas
mkdir makefiles
cd makefiles
cmake -G "Unix Makefiles" ../

完了以后：

make

再然后：

make install

四、测试

输入如下命令：

lasinfo ../test/data/TO_core_last_clip.las

会输出如下类似信息：
