Unable to find full path g++ and gcc
提问by user3306996
I am trying to install Eclipse Helios on Linux and I manage to get eclipse installed. However, upon running a simple hello world program, errors occurred. It says unable to find full path for g++ and gcc and thus I am unable to run the program.
我正在尝试在 Linux 上安装 Eclipse Helios，并且我设法安装了 Eclipse。但是，在运行一个简单的 hello world 程序时，发生了错误。它说无法找到 g++ 和 gcc 的完整路径，因此我无法运行该程序。
Does it got to do with my linux installation or eclipse installation? Please advice. Thank you.
它与我的 linux 安装或 eclipse 安装有关吗？请指教。谢谢你。

Okay, Possibilities are either you didn't installed g++ before (or after) installing eclipse or the path was not detected by eclipse. Since Eclipse's installation itself does not include g++ you need to install it separately using terminal.
好的，可能是您在安装 eclipse 之前（或之后）没有安装 g++，或者 eclipse 未检测到路径。由于 Eclipse 的安装本身不包含 g++，因此您需要使用终端单独安装它。
Also as you didn't mention which Linux are you on, I am assuming Ubuntu/Debian.Now you need to check whether g++ is installed or not on your system.To do this: Open Terminal by pressing CTRL+ALT+T and then enter the following command
此外，由于您没有提到您使用的是哪个 Linux，我假设您使用的是 Ubuntu/Debian。现在您需要检查您的系统上是否安装了 g++。为此：按 CTRL+ALT+T 打开终端，然后输入以下命令
g++ <some c++ filename and path> -o output
and press enter.If it compiles that means G++ is installed else it'll say command not found.In case you don't have g++ installed use this command (this is ONLY for UBUNTU and its derivatives)`
然后按回车。如果它编译意味着安装了 G++，否则它会说找不到命令。如果你没有安装 g++，请使用这个命令（这仅适用于 UBUNTU 及其衍生产品）`
sudo apt-get install g++
Also in case of previous broken installation, first use this command`
同样在以前安装损坏的情况下，首先使用此命令`
sudo apt-get autoremove g++
and then install! Now to get the path of the newly installed compiler use this
然后安装！现在要获取新安装的编译器的路径，请使用它
$ which g++
and put the output path in Eclipse preferences
并将输出路径放在 Eclipse 首选项中

first of all title is misleading, i will recommend to change it to get better answers. check where your g++ and gcc executable are located: Terminal:
首先，标题具有误导性，我会建议更改它以获得更好的答案。检查您的 g++ 和 gcc 可执行文件所在的位置：终端：
$ which g++
$ which gcc
output is likely gooing to be:
输出很可能是：
/usr/bin/g++
/usr/bin/g++
and
和
/usr/bin/g++
/usr/bin/g++
(in this point if you get a path for gcc/g++ your linux installation is likely ok and eclipse can't find gcc and g++)
（在这一点上，如果您获得 gcc/g++ 的路径，则您的 linux 安装可能没问题，并且 eclipse 找不到 gcc 和 g++）
then go to eclipse yourProject > properties and set path/command for gcc and g++.
然后转到 eclipse yourProject > properties 并为 gcc 和 g++ 设置路径/命令。

On RHEL 7.3 you can do this to install the 64-bit gcc/g++compiler:
在 RHEL 7.3 上，您可以执行以下操作来安装 64 位gcc/g++编译器：
$ yum install gcc-c++.x86_64
$ g++ --version

Have you installed gcc? If you have installed, maybe you should configurate eclipse? It might be the problem.
你安装gcc了吗？如果你已经安装，也许你应该配置eclipse？这可能是问题所在。
