如何在制作GCC 4.9.1时解决"找不到可用的依赖项样式"错误

Question

我想安装gcc 4.9.1.所以我下载了tar球,安装了依赖项,并运行配置 -

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

这工作得很好.

但当我采取下一步并解雇时make,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并且找到时会出现错误none.

任何人都能解释一下是什么意思checking dependency style of /usr/bin吗？

知道什么时候出现这个问题以及如何解决它.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arm所告知的那样,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

上CentOS/RedHat,这很可能是因为你没有G ++安装

$ 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

两件事情：

1. 您不应该在源代码树中构建GCC。它没有明确禁用，但不受支持。使用外部构建目录重试。在HTML安装手册中。

2. 检查config.log文件。每个目录一个，一个包含“找不到可用的依赖样式”消息。您应该能够在此处找到更多详细信息。

编辑以下额外信息：

看来您已CXX=/usr/bin在环境中进行设置。应该是CXX=/usr/bin/g++。
