在 Ubuntu 16.04 上运行 make 构建 Sage 时出错

我正在尝试在 Ubuntu 16.04 上编译 Sage。我下载了二进制文件并安装了一个包。我在 Sage 目录中运行“make”，结果如下：

下列软件包可能未能构建（不一定在此次运行“make all”期间）：

构建目录可能包含配置文件和其他可能有用的信息。警告：如果您现在再次运行“make”，则默认情况下将删除构建目录。将环境变量 SAGE_KEEP_BUILT_SPKGS 设置为“yes”以防止这种情况发生。

Makefile：16：目标“全部”的配方失败：*** [全部] 错误 1

按照错误信息中的建议，我更改了我的环境变量，如下所示（我添加了第二行）：

~/Desktop/SageMath$ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" export SAGE_KEEP_BUILT_SPKGS=yes

然后，按照建议这里我执行了下列操作：

sudo apt-get 安装 libstdc++6

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get 更新

sudo apt-get 升级

当我运行“make”时，仍然出现以下错误：

> [sagelib-7.3]  [sagelib-7.3] real 0m4.203s [sagelib-7.3] user 0m3.516s

有人能提供建议吗？任何建议都将不胜感激。谢谢！

  1. 验证您当前的 libstdc++ 是否具有GLIBCXX_3.4.21：

    strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4.21

  2. 创建符号链接如下：

    ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /home/davidk/Desktop/SageMath/local/lib/libstdc++.so.6

  3. make
