我在从最新的 2017.03 AMI 启动的 EC2 实例上使用 Amazon Linux (ami-6df1e514）。
该发行版自 2013 年起附带g++4.8.3。我需要一些可以编译 C++14 的更新版本。
有什么办法可以gcc从某种二进制文件中安装更新的版本，还是我只能从源代码进行编译？
我在亚马逊仓库中没有看到任何看起来最新的内容：

是否有替代方案、测试 repo 或者包含更新软件包的东西？
答案1
使用新的 Amazon Linux 2https://aws.amazon.com/amazon-linux-2/其默认 repo 中有 gcc v7.2.1。
答案2
目前看起来是这样的：
# yum list \*gcc10\*
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
Installed Packages
gcc10.x86_64 10.3.1-1.amzn2.0.1 @amzn2-core
gcc10-binutils.x86_64 2.35-21.amzn2.0.1 @amzn2-core
gcc10-binutils-gold.x86_64 2.35-21.amzn2.0.1 @amzn2-core
Available Packages
gcc10-binutils.i686 2.35-21.amzn2.0.1 amzn2-core
gcc10-binutils-devel.x86_64 2.35-21.amzn2.0.1 amzn2-core
gcc10-c++.x86_64 10.3.1-1.amzn2.0.1 amzn2-core
gcc10-gdb-plugin.x86_64 10.3.1-1.amzn2.0.1 amzn2-core
gcc10-plugin-devel.x86_64 10.3.1-1.amzn2.0.1 amzn2-core
因此只需执行：
yum install -y gcc10.x86_64 gcc10-c++.x86_64并检查：
# gcc10-gcc --version
