      最近用到一个和同事合作的项目,也在eclipse下开发,工程代码比较多,移植时碰到一些问题,与大家分享一下:
     原因:工程编译时很多地方用到其他目录下的依赖文件,依赖一个指定的用户ubuntu,而这个我的eclipse安装使用用户不同,该代码的级联问题再多,所以决定在本机下创建ubuntu用户来解决。
        步骤:
                 1.创建新用户 ubuntu,在其主目录 /home/ubuntu/ 下面创建 workspace目录;
                 2.注销切换用户,用新的ubuntu用户登录;
                 3.打开eclipse,发现打不开,报错,提示进入
/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1348562618674.log 查看错误日志,
gedit 1348562699374.log
OK ,报错信息如下:
!ENTRY org.eclipse.osgi 4 0 2012-09-25 16:45:03.318

信息挺多,大致意思就是 eclipse启动时需要加载的一些库在
/home/ubuntu/.swt/lib/linux/x86/
下找不到,事实上ecilpse运行时在用户的主目录下都会产生2个目录,.eclipse和 .swt ;
.swt就是存放运行时库的。
       
OK ,文件找到就好解决了,找到原来用户目录下的
.swt/lib/linux/x86/
所有文件,copy到当前目录,在运行eclipse就OK了;
问题2:运行起来后发现原有的C/C++工程无法编译,文件图标全都是gedit打开风格,看来时CDT插件的问题,安装CDT插件:
help ---》install new software
打开如下地址:CDT - http://download.eclipse.org/tools/cdt/releases/helios,
安装完成重启就OK 了。
