我将binutils-2.25.1安装到/usr/local/binutils-2.25.1,配置了

../configure --prefix=/usr/local/binutils-2.25.1 --enable-plugins --enable-gold --disable-werror

我想构建RPM包 - 使用LTO支持的gcc,它使用来自/usr/local/binutils-2.25.1的链接器ld.

我尝试:

Summary: The GNU Compiler Collection
Name: gcc-custom
Version: 4.9.3
%define full_name gcc-%{version}
%define binutils_path /usr/local/binutils-2.25.1
Release: 0

Requires(postun): /sbin/ldconfig
