T113S3在Tina系统下，选择自带的第三方库编译烧录后，在开发板目录下找不到对应的.so动态库
-
选择modbus这个Tina自带的第三方库，烧录后没有libmodbus.so这个动态库，find命令查找后只有libmodbus.contrl和libmodbus.list这2个文件root@TinaLinux:/# find . -name "*modbus*" ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbus_symbols_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusadu_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusclient_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbuscommevent_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusdevice_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusrtuserialmaster_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusrtuserialslave_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusserver_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbustcpclient_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbustcpserver_p.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusclient.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusdataunit.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusdevice.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusdeviceidentification.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbuspdu.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusreply.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusrtuserialmaster.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusrtuserialslave.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbusserver.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbustcpclient.h ./rom/usr/lib/arm-qt/include/QtSerialBus/qmodbustcpserver.h ./rom/usr/lib/opkg/info/libmodbus.control ./rom/usr/lib/opkg/info/libmodbus.list ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbus_symbols_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusadu_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusclient_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbuscommevent_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusdevice_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusrtuserialmaster_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusrtuserialslave_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbusserver_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbustcpclient_p.h ./usr/lib/arm-qt/include/QtSerialBus/5.12.9/QtSerialBus/private/qmodbustcpserver_p.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusclient.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusdataunit.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusdevice.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusdeviceidentification.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbuspdu.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusreply.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusrtuserialmaster.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusrtuserialslave.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbusserver.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbustcpclient.h ./usr/lib/arm-qt/include/QtSerialBus/qmodbustcpserver.h ./usr/lib/opkg/info/libmodbus.control ./usr/lib/opkg/info/libmodbus.list root@TinaLinux:/# cd usr/ root@TinaLinux:/usr# find . -name "libm*.so*" ./lib/arm-qt/lib/libm.so.6 ./lib/arm-qt/qml/QtQml/Models.2/libmodelsplugin.so ./lib/libmenuw.so ./lib/libmenuw.so.5 ./lib/libmenuw.so.5.9 root@TinaLinux:/usr# find . -name "libm*" ./lib/arm-qt/lib/libm.so.6 ./lib/arm-qt/qml/QtQml/Models.2/libmodelsplugin.so ./lib/libmenuw.so ./lib/libmenuw.so.5 ./lib/libmenuw.so.5.9 ./lib/opkg/info/libmodbus.control ./lib/opkg/info/libmodbus.list ./lib/opkg/info/libmymath.control ./lib/opkg/info/libmymath.list -
在系统配置里面，有个down rootfs size，这个选项会把用不上的so裁剪掉，关掉这个选项就可以
