此时已经可以查看到EC25
编译拨号软件
下载Quectel_QConnectManager_Linux软件拨号
因为扩展了系统空间，选择直接将此压缩包放在openwrt设备上解压
opkg update && opkg install unzip make gcc
#解压压缩包
unzip Quectel_QConnectManager_Linux_V1.6.0.16.zip
编译
在编译过程中发现缺失两个lib库 pthread,dl
选择从工具链中直接复制两个库到设备
下载工具链并解压到linux系统下
# 文件位置
# pthread
/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libpthread.a
# dl
/openwrt-toolchain-22.03.2-bcm27xx-bcm2711_gcc-11.2.0_musl.Linux-x86_64/toolchain-aarch64_cortex-a72_gcc-11.2.0_musl/lib/libdl.a
将这两个文件放到openwrt系统/usr/lib目录下，然后进入刚才解压拨号软件的文件夹中，执行make命令
cd quectel-CM
make release
等待执行结束即可得到quectel-CM二进制文件，执行后即可拨号
./quectel-CM
