DLang 编译实验

一直在寻找一个可以编译运行又有脚本语言便利性的语言。

我要的是编译后可以到处运行（相同OS），我非常讨厌，很多语言，还需要在OS 安装一个环境才能运行

如：Java

 

D语言是由Digital Mars公司开发的编程语言，起因是为了改进C＋＋。它与C二进制兼容（不完全），可编译为本地码，有GC也可手动管理内存，语法上借鉴多种语言，模板则在C＋＋的基础上做了相当大的扩充。D 语言既有 C 语言的强大威力，又有 Python 和 Ruby 的开发效率。它是一种集垃圾回收、手工内存操作、契约式设计、高级模板技术、内嵌汇编、内置单元测试、Mixin 风格多继承、类 Java 包管理机制、内置同步机制、内建基本运行时信息的系统级编程语言。

 

我做了一下测试，D语言满足我的需求

 

安装

 

$ wget http://ftp.digitalmars.com/dmd_2.057-0_amd64.deb
$ sudo apt-get install libc6-dev

$ sudo dpkg -i dmd_2.057-0_amd64.deb

 

 

$ cat hello.d 
#!/usr/bin/rdmd
import std.stdio;
void main() {
    writeln("Hello, world!");
}

 

 

 

$ ./hello.d 
Hello, world!

 

 

编译测试

 

 

$ dmd hello.d
$ dmd hello.d
Hello, world!

 

将编译后的hello文件复制到其他机器上（注：没有安装dmd环境，一台全新安装CentOS 5.6 的机器）

 

scp hello [email protected]:/tmp
ssh [email protected]
cd /tmp
./hello

Hello,world!

 在新机器上运行成功，表示D语言使用的是GLibc 库，不依赖dmd环境，也可能是静态编译，将dmd 速要的库编译进了hello文件

 

 

$ strace ./hello
execve("./hello", ["./hello"], [/* 20 vars */]) = 0
