C 编译器无法在 Ubuntu 12.04 中创建可执行文件

Question

我正在尝试为莱特币配置 cpuminer，我得到了

checking whether the C compiler works... no
configure: error: in `/home/username/cpuminer-2.2.3':
configure: error: C compiler cannot create executables
See `config.log' for more details

这是在 Ubuntu 12.04 x64 上。

我不确定会发生什么，但我已经运行更新并安装了 gcc。我读了很多文章，但它们似乎指向不同的东西。

config.log 的输出是

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by cpuminer configure 2.2.3, which was
generated by GNU Autoconf 2.68.  Invocation command line was

  $ ./configure CFLAGS=-03

看起来 gcc 正在使用选项 -03 而不是 -O3 调用，导致它出错。检查您可能指定的任何 CFLAGS。
