正在检查主机系统类型...无效配置“x86_64-unknown-linux-gnu”：无法识别计算机“x86_64-unknown”

问：

./configure尝试编译时出现以下错误：

ltconfig: you must specify a host type if you use `--no-verify'
Try `ltconfig --help' for more information.
configure: error: libtool configure failed

我尝试使用以下方法设置主机 var

./configure --host=$[my system]

但新主机名出现相同的错误。 我仍然不熟悉使用配置和生成文件，但我的猜测是我输入了错误的主机名，或者完全错误地执行此操作。
