Question

我想安装gcc 4.9.1。所以我下载了tar ball，安装了依赖项，并使用 -

运行config

./configure --program-suffix=-4.9.1 --disable-multilib

工作得很好。

但是当我采取下一步并解雇make时，我收到以下错误：

configure: error: no usable dependency style found
make[2]: *** [configure-stage1-gcc] Error 1

当make尝试checking dependency style of /usr/bin并找到none时出现错误。

任何人都可以解释checking dependency style of /usr/bin的含义吗？

知道何时出现此问题以及如何解决此问题。我做了一些搜索，找不到任何东西。

我正在使用64位RHEL 6.x机器进行编译。

编辑1：

正如胳膊所建议的那样，我在个人config.log中遇到了错误。终于找到了它。这是一些内容

Answer 1

在CentOS/RedHat上，很可能是因为您没有安装 g ++

$ which g++
// not found

安装 Development Tools 将解决此问题：

$ yum groupinstall 'Development Tools'
$ which g++
/usr/bin/g++

Answer 2

两件事：

您不应在源树中构建GCC;它未明确禁用，但不受支持。再次尝试使用外部构建目录。它位于HTML安装手册中。
检查config.log个文件。每个目录将有一个，其中一个将包含“找不到可用的依赖样式”消息。你应该能够在那里找到更多细节。

编辑以下额外信息：

您的环境中似乎已设置CXX=/usr/bin。它应该是CXX=/usr/bin/g++。
