有用crossdev安装insight的么？我一直安装失败，请大虾指教

lofeng

# crossdev -S -s4 --ex-gdb --ex-insight --target arm-unknown-linux-gnu
因为需要调试，所以想装个insight，毕竟对于我等菜鸟来说gdb文本界面有点困难。但是安装一直失败，相关log中信息如下。

# cat /var/log/portage/cross-arm-unknown-linux-gnu-insight.log

!!! All ebuilds that could satisfy "cross-arm-unknown-linux-gnu/insight" have been masked.
!!! One of the following masked packages is required to complete your request:
- cross-arm-unknown-linux-gnu/insight-6.8 (masked by: missing keyword)
- cross-arm-unknown-linux-gnu/insight-6.7.1-r1 (masked by: missing keyword)

根据提示，我在/etc/portage/package.keywords中添加了cross-arm-unknown-linux-gnu/insight，问题依旧

# vim /usr/portage/dev-util/insight/insight-6.8.ebuild

KEYWORDS="~alpha ~amd64 ~ppc ~sparc ~x86"

其中并没有arm，但是我安装的insight是:
host为x86 gentoo
target为arm
这里的KEYWORDS应该为x86即可了
为什么我修改了/etc/portage/package.keywords还是提示missing keyword呢？

发现这个overlay竟然是系统portage的symbol link，既然这样，为什么还要设置这么个overlay呢？

# ls -l /usr/local/portage/cross-arm-unknown-linux-gnu/

如果portage不支持安装target为arm的insight，那岂不是需要自己下载源码来编译insight，编译时加上
[color="Red"]--target arm-unknown-linux-gnu这个参数？

没有人这样来使用crossdev的么？
