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试图检查/usr/bin的依赖样式并且它找不到时,会出现错误.
任何人都可以通过检查/usr/bin的依赖样式来解释是什么意思吗？
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.
EDIT 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

解决方法
两件事情：
>你不应该在源代码树中构建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：
您似乎已在环境中设置了CXX = /usr/bin.它应该是CXX = /usr/bin/g.
