我想使用一些仅在该语言的最新版本中可用的C ++功能。问题是Ubuntu 15.04(Vivid Vervet)已安装4.9.2,并查看我从apt-get install gcc获得的输出:
Reading package lists... Done
Building dependency tree
Reading state information... Done
gcc is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
2 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n]
它说它已经是最新版本了。我不明白为什么

Ubuntu 15.04不再受支持,也许您应该升级到新版本。旧版本的Ubuntu通常没有最新版本的软件包,您必须升级发行版或从ppa安装软件包或从源代码构建它。
