解决OpenWRT安装第三方包Incompatible with the architectures configured错误

起因起了把家里路由器更新到新版本OpenWRT的念头很久了，周末终于克服自己的懒病，下载了OpenWRT 19.07.4的安装包，更新Linksys WRT1900ACS路由器的系统。修改了IP地址，把Wifi打开后，驾轻就熟地修改了相关的配置，增加了第三方源，准备开始安装你懂的SS和ChinaDNS等组件。没想到往常屡试不爽的opkg install命令返回了安装失败提示： Incompatible with the architectures configured 仔细比对了所有的配置，确认没有错误，但是安装新增的第三方包时总是报错。解决方法试了N多种方法，还是不行，正准备放弃装回原来ROM时，突然发现运行opkg print-architecture返回的CPU架构型号是 arch all 1 arch noarch 1 arch arm_cortex-a9_vfpv3-d16 10 比原来系统打印出来的架构型号多了一个d16,而第三方源的库里貌似没有arm_cortex-a9_vfpv3-d16这样一个型号的源,尝试修改/etc/opkg.conf文件，把原来CPU型号列表增加不带d16行。 arch all 1 arch noarch 1 arch arm_cortex-a9_vfpv3 8 arch arm_cortex-a9_vfpv3-d16 10 再运行opkg install，包装成功。
