当我尝试在nginx src路径中运行“configure”命令时，出现了错误。

我测试了nginx默认安装，没有任何参数，除了路径的--prefix。它工作正常，nginx安装得很流畅。 我检查了参数，发现“--with-cc-opt =' - m32 -march = i386'”，我的操作系统是64位，所以我删除它，并运行命令。 它照常工作....

之前我曾经历过这个错误。希望我的两个问题可以帮助你缩小你的范围：
1）我错误地尝试使用C ++编译nginx，实际上它需要C。
2）我使用的是不兼容的插件。我使用的TCP代理插件与最新版本的nginx不兼容。问题是内部变化超出了插件的支持。
快乐狩猎。

如果在OS X上，就像我一样，请尝试按照bug report进行操作。
基本上做：
brew install pcre
并将其添加到./configure
--with-ld-opt="-L /usr/local/lib"
