How to install gcc-4.8 in Ubuntu 12.04 from the terminal

up vote8down votefavorite

2

I checked the gcc version on my system.

It is currently at 4.6.3. I read that gcc-4.8 is out.

I tried the following commands without success:

sudo apt-get install gcc (gcc is already the newest version)sudo apt-get install gcc-4.8 (unable to locate package)

Does anyone know how to install this package on 12.04?

@maggotbrain's answer worked for me, though I had to add: sudo apt-get install gcc-multilib as I was running into this issue: superuser.com/questions/432202/make-fails-compiling-gcc – skillman May 6 at 15:56

Is GCC-4.8 available for 12.04 Precise now?

The short answer is: gcc-4.8 is currently available for 12.04(Precise) only by compiling the source(see below for details).

Update: As of 4/13/2013, there is currently a dev release of gcc 4.8 for 12.04(precise) available athttps://launchpad.net/~ubuntu-toolchain-r/+archive/test.

One can install .deb files from here.

Release Announcement

The announcement for the release of gcc-4.8 was made on March 22nd, so you probably won't be seeing this in an official repository just yet.

However, it appears that Launchpad does have a PPA available for the toolchain test builds that does include gcc-4.8, here: https://launchpad.net/~ubuntu-toolchain-r/+archive/test

According to the changelog and package list, there are debs for i386, amd64, arm, and powerpc and were built against raring 13.04. This package is not available for 12.04 Precise users at this time.

The latest available version of gcc, for 12.04, is 4.7.2-11 and is available in the toolchain PPA.

Adding the toolchain/test PPA:

To add the PPA to your system, open a terminal(Ctrl+Alt+t) and run the following commands:

sudo add-apt-repository ppa:ubuntu-toolchain-r/testsudo apt-get updatesudo apt-get install gcc-4.7-base

• What are PPAs and how do I use them?
• Are PPA's safe to add to my system and what are some "red flags" to watch out for?

What C++ features are available in gcc-4.8 that are not available in gcc-4.7.2?

• According to GNU.ORG, gcc-4.7, supports a number of C++11 features.

• As of the gcc-4.8 release, gcc-4.7 does not support 8 out of 64 features (See C++0x/C++11 Support in GCC)

• These features are:

  Language Features- Rvalue references for *this- Generalized attributes- Alignment support- Inheriting constructorsConcurreny- Bidirectional Fences- Memory model- Abandoning a process and at_quick_exit- Thread-local storage 

• For a full list of changes in gcc-4.8, see the Changelist

I need these gcc features on 12.04 Precise, now. How can I get them?

Building GCC-4.8 from source:

If you need gcc-4.8 on 12.04 now, your only option is to build it from source.

Please read the GCC installation FAQ prior to installation.

You can download gcc-4.8 from one of gnu.org's mirror sites or directly from their SVN server.

Here is an example of steps to compile from source (see here for additional details.) Note that these may vary depending on your system and preferences.

1. Download the source code

   • Make a build directory ( mkdir gcc-build && cd gcc-build)
   • Download the source file: wget http://www.netgull.com/gcc/releases/gcc-4.8.0/gcc-4.8.0.tar.bz2 (adjust this command to use an appropriate mirror site.
   • Unzip the file (tar -xvjf <file name>)

2. Install some additional libraries (sudo apt-get install libgmp-dev libmpfr-dev libmpc-dev libc6-dev)

3. Compile the source: ./gcc-4.8.0/configure --prefix=/app/gcc/4.8.0
4. Run make (This will take some time to complete. Go make some coffee, or bake some cookies. ;-))
5. Install the code: sudo make install

Once this process has completed, run the command gcc --version to verify that the installation has completed successfully. You should see something similar to the following output:

maggotbrain@foucault:~$ gcc --versiongcc (Linaro 4.8.0) 4.8.0Copyright (C) 2013 Free Software Foundation, Inc.This is free software; see the source for copying conditions.  There is NOwarranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

At this time, there does not appear to be a published schedule as to when this backport will be available on 12.04. Although there is some additional discussion regarding gcc-4.8 here:https://bugs.launchpad.net/ubuntu/+source/gcc-4.7/+bug/1159547

The bottom line: Thank all those folks who provide easy to install Ubuntu backports for you. Give them some of the cookies that you baked while running make. ;-)

Excellent answer, except: E: Unable to locate package gcc-4.8 – John Dibling Apr 4 at 11:14

So answer above works, at least for manual install. Though even after sudo make install, runninggcc still just runs the stock version 4.6.3. Even trying gcc-4.8 or gcc-4.8.0 doesn't work. Running/app/gcc/4.8.0/bin/gcc appears to be the only thing that works for me. I mean it is kind of lame but at least it works.

maybe symlinks are not updated after installation. You can run

ln -s /app/gcc/4.8.0/bin/gcc /usr/bin/gcc

and now gcc command will run 4.8 version.

It should be built-in with Ubuntu 12.04. however, you can try this:

sudo apt-get update                    sudo apt-get install gcc-4.8

Linux 编译安装 GCC 4.8

Filed under: Article,Blablabla... — 标签4.8,centos,gcc,gcc 4.8,linux,安装,编译 — OWenT @ 上午 10:01

GCC4.8发布啦，这个脚本在之前4.7的基础上做了点改进，移除一些过时的组件,增加了检测不到时自动下载源码包
PS：4.8的新功能对于4.7貌似不是太多，生成属性、align模板、继承构造、线程内存池,还有什么来着？

编译安装 GCC 4.8.X

准备环境及依赖项

1. 支持 ISO C++ 98 的编译器（GCC 4.7.2 的中期一个patch导致的整个项目开始转为由C++编译）
2. 用于创建Ada编译器的GNAT
3. 支持POSIX的shell或GNU bash
4. POSIX或SVR4的 awk工具
5. GNU binutils
6. gzip 版本1.2.4及以上     （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）

8. GNU make 工具 版本3.80及以上 （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）
9. GNU tar工具 版本1.14及以上   （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）
10. perl 版本5.6.1及以上      （此处可下载 http://www.perl.org/）
11. jar或zip和unzip工具 （此处可下载 http://www.info-zip.org)
12. gmp库 版本5.0.2及以上 （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）
13. mpfr库 版本2.4.2及以上 （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）
14. mpc库 版本0.8.1及以上 （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org 下载 ）
15. isl 版本 0.11.1 （可由GNU镜像列表 http://www.gnu.org/prep/ftp.html 或自动选择最佳镜像 http://ftpmirror.gnu.org  中gcc目录中的infrastructure目录下载 ）
16. cloog 版本0.18.0（此处可下载 ftp://gcc.gnu.org/pub/gcc/infrastructure/ ）

 

我编译的环境

# 应该就编译完啦

# 64位系统内，如果编译java支持的话可能在gmp上会有问题，可以用这个选项关闭java支持 --enable-languages=c,c++,objc,obj-c++,fortran,ada

# 再把$PREFIX_DIR/bin放到PATH

# $PREFIX_DIR/lib （如果是64位机器还有$PREFIX_DIR/lib64）[另外还有$PREFIX_DIR/libexec我也不知道要不要加，反正我加了]放到LD_LIBRARY_PATH或者/etc/ld.so.conf里

# 再执行ldconfig就可以用新的gcc啦

History:

2013-03-26Created2013-04-11改进脚本，增加统一编译选项，增加对binutils和gdb可选包的编译，增加自动把PREFIX_DIR变为绝对路径的问题，统一目录组织，修复环境变量的一些小问题
