ubuntu9.10中安装eCos并建立eCos开发环境

本文主要介绍了在虚拟机linux中下载和安装最新版本eCos并建立eCos开发环境的方法与步骤。本人使用的linux虚拟机是ubuntu9.10，其它linux版本的eCos安装方法应该类似。

1. 安装 tcl

Tcl ，工具命令语言 Tool Command Language。

linux系统里一般不自带安装tcl，如果虚拟机中没有安装tcl，则要先安装tcl。

2.  下载 ecos-install.tcl在线安装脚本文件

下地址：ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl

或者执行如下命令直接在linux中下载：

上述命令会把 ecos-install.tcl下载当前目录下。

3.  在shell中执行ecos-install.tcl

执行如下命令：

然后就开始安装eCos了，安装过程中要选择源和一些参数镜像地址、安装路径、gnu工具链选择等，按提示操作就是了。本人选择安装在了/opt/ecos/路径下。下面是安装过程（打蓝色部分根据你的情况进行操作）：

In future, to establish the correct environment for eCos,
run one of the following commands:
. ./ecosenv.sh (for sh/bash users); or
source ./ecosenv.csh (for csh/tcsh users)

It is recommended you append these commands to the end of your
shell startup files such as $HOME/.profile or $HOME/.login

注意上面打红色部分。这段英文提供了设置eCos环境的方法。按推荐的方法进行操作即可。

4.  安装 libstdc++.so.5库文件

上面已经安装好eCos并建立了eCos的环境变量。但此时运行eCos下的图形配置工具：configtool，或命令行配置工具：ecosconfig是会出错的，错误如下：

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

这是因为linux虚拟机中没有安装libstdc++ v3 (/usr/lib/libstdc++.so.5)兼容库导致的。

本人尝试了下使用apt-get install命令安装，但在ubuntu9.10中不能安装成功，因此，采用了手动安装的方法。具体参见：

ubuntu下安装eCos 3.0时所必需库libstdc++5下载 一文的介绍。

至此，完成了安装eCos并建立eCos开发环境。
