安装无根的GCC-4.9 - 添加路径和二进制文件和额外的 [英] installing GCC-4.9 without root - adding paths and binaries and extra

问题描述

我刚刚使用链接安装了gcc 4.9 这里，它是一个非常好的链接。但我只有一个问题，我不想尝试不要搞乱 - >链接库和路径变量。

我们大学有一个集群，我将它安装在我的主目录中（没有root）。现在我的home /目录包含这个文件夹，其中包含所有gcc文件夹：

  bin 
 include 
 lib 
 lib64 
 libexec 
 share 
  

我要做什么做额外的链接指向bin文件夹中的g ++ / gcc二进制文件吗？例如，设置ld_library_path，设置二进制路径（export PATH = /home/asdf/gcc4.9/bin:$PATH）。等等。

任何人都可以提供关于使用gcc / g ++ 4.9（由我安装）绕过由root安装的旧版gcc所需做的所有事情的详细信息。

我还必须将lib和lib64添加到ld_library_paths吗？我将不得不使用而不是 >包含文件（例如＃inlcudeset或#include，它包括来自gcc4.9而不是旧版本）或者使用-I

欢迎任何建议/讨论/评论。我知道这可能被标记为重复，但对于那些想要用c ++ 11尝试新的gcc-4.9而不搞乱环境变量的人来说真的很有用。

PS：我不问如何导出或设置环境变量。我在问什么所有环境变量需要使用我的非root版本的gcc，而不是root的旧版本，而不是弄乱 ld 路径和运行时路径。

谢谢！如果你用 - 前缀= / home / myname / gcc4.9来编译你的编译器 / code>（调整以匹配你的系统，显然），那么编译器应该知道包含路径等。

确保你的路径 /home/myname/gcc4.9/bin 在 / usr / bin 之前或你的任何地方其他的gcc已经安装好了，一切都应该像平常一样工作。在我的机器上，我已经从我自己的版本安装了gcc 4.8.2，并且从gcc的linux安装程序中安装了gcc 4.6.3（因为它是一个相当老的发行版）。只要我按照正确的顺序设置路径，它就会自动地运行。

您需要设置 LD_LIBRARY_PATH ，但include路径和静态库应该由gcc自己处理。

i just installed gcc 4.9 using the link here and it is a very good link. But I have only one problem which i dont want to try not to mess up --> linking the libraries and path variables.

we have a cluster in our college and i installed this in my home directory (without root). Now my home/ directory contains this folder where all the gcc folders are :

bin  
include  
lib  
lib64  
libexec  
share

What all do i have to do to point to the g++/gcc binary in bin folder with additional linking ? For example, set ld_library_path, set binary paths (export PATH = /home/asdf/gcc4.9/bin:$PATH) . etc..

Can anyone provide details on what all needs to be done to use gcc/g++ 4.9 (installed by me) by bypassing the older version of gcc installed by root.

Do i have to add lib and lib64 to the ld_library_paths as well ? Will i have to use " " instead of < > to include files (e.g. # inlcude "set" or #include and it includes from gcc4.9 and not the old one ) Or explicitly provide the include path using -I

Any suggestions/discussions/comments are welcome. I am aware this may marked as duplicate, but it will really be useful to all the people out there who want to try the new gcc-4.9 with c++11 without messing up the environment variables.

PS: I am not asking how to export or set an environment variable. I am asking what all environment variables are required to use my non-root version of gcc and not the root's older version and not mess up the ld paths and so paths during runtime.

thanks !!

解决方案

If you build your compiler with --prefix=/home/myname/gcc4.9 (adjust to match your system, obviously), then the compiler should "know" that the include paths etc.

All you need beyond that is to make sure your path has /home/myname/gcc4.9/bin before /usr/bin or wherever your other gcc is installed, and everything should work just like normal. On my machine, I have gcc 4.8.2 installed from my own build and gcc 4.6.3 from the linux installer for gcc (because it's a fairly old distro). And as long as I have the paths set in the right order, it works "automagically".

You will need to set LD_LIBRARY_PATH, but include-paths and static libraries should be handled by gcc itself.
