我使用的是 Ubuntu 13.04 64 位。这是错误消息：

Ubuntu 13.04 是否太新，gcc 无法检测到（它检测到 x86_64-unknown-linux-gnu-gcc）。我使用 Linux Mint 14 32 位编译成功。
编辑：检查 config.log，好像有一个测试失败：

我将尝试安装 libisl 以查看其运行情况。
答案1
我能够检测到缺失的依赖项并修复它：检查 config.log 输出以查看缺少哪些库并安装它。例如，检查我第一篇文章中编辑部分中的 config.log；查看开头的几行，我缺少库 isl。我安装了它，问题就解决了。
您可以做同样的事情。虽然后来我遇到了另一个错误，我不得不禁用 multilib（--disable-multilib）。
