ubuntu 编译安装gcc 6.3

1. 参考博客编译安装gcc 6.3

 对make出错解决:

 错误一

error: dereferencing pointer to incomplete type 'struct ucontext'

   解决方法:

In order to have make to work you have to modify the file make_folder/libgcc/config/i386/linux_unwind.h where make_folder is the folder where you type the make command.

In linux_unwind.h you have to change struct ucontext *uc_ = context->cfa; on line 61 to struct ucontext_t *uc_ = context->cfa;

  错误二: 

aggregate ‘sigaltstack handler_stack’ has incomplete type and cannot be defined
   struct sigaltstack handler_stack;

根据Fix sanitizer build against latest glibc 修改对应文件后 重新编译
