我想安装 eclipse-cdt 进行 c++ 开发。但它似乎无法在 ubuntu 中单独安装。如果不能单独安装，为什么会有单独的包？
[balakrishnan@mylap ~]$ sudo apt-get install eclipse-cdt 正在读取软件包列表...完成 正在构建依赖关系树 正在读取状态信息...完成 将安装以下额外软件包：

答案1
我建议从 eclipse.org 安装 eclipse。转到http://www.eclipse.org/downloads/并下载您喜欢的 eclipse 包。然后转到http://java.com/en/download/manual.jsp?locale=en并下载适合您操作系统的 Java 版本（i386 为“Linux”，amd64 为“Linux x64”）。将两个存档解压到一个文件夹（我通常创建 ~/bin）。您应该得到两个文件夹：eclipse 和 jre1.7.0_09。
然后编辑文件 eclipse/eclipse.ini，添加：
-vm
../jre1.7.0_09/bin/java
以下
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
这将使 eclipse 始终使用 Oracles 的 java。Eclipse 仅经过测试可在 oracle 的 java 上运行。
使用此方法，您可以进行多次 eclipse 安装，每个安装中只需要安装所需的工具。
