Hi,
Are you sure the library is of the correct architecture ?
Interested in AI ? www.idiap.ch
Please read the Qt Code of Conduct - https://forum.qt.io/topic/113070/qt-code-of-conduct -
@houyawei The linker error messages seem to all relate to hardware abstraction layer (HAL) functions for the target IOT device. Do you have all the required Tuya/hardware libraries in the project so they get added to the linker call?
Further to SGaist's comment, are you cross-compiling for a target device or compiling on the device that is to run the program?
@JoeCFD CFD LD_LIBRARY_PATH is used by ld.so at run time to find dynamic libraries. This is a link-time failure with static libraries. The missing functions might be in a dynamic library, which would be either found explicitly listed in the ld command line (as for libQt5Core.so in the error msg), or named (-l option) and found on a search path (-L option).

@SGaist I think this library should be available normally, after I use the official demo to compile, it can run normally.

@houyawei The linker error messages seem to all relate to hardware abstraction layer (HAL) functions for the target IOT device. Do you have all the required Tuya/hardware libraries in the project so they get added to the linker call?
Further to SGaist's comment, are you cross-compiling for a target device or compiling on the device that is to run the program?
@JoeCFD CFD LD_LIBRARY_PATH is used by ld.so at run time to find dynamic libraries. This is a link-time failure with static libraries. The missing functions might be in a dynamic library, which would be either found explicitly listed in the ld command line (as for libQt5Core.so in the error msg), or named (-l option) and found on a search path (-L option).
@ChrisW67 I only added all the .h files in the sdk/include directory, and sdk/lib/libtuya_iot.a.
They have other library versions for cross-compilation（https://github.com/TuyaInc/tuya_DeviceOS_SDK/tree/master/IOT Device OS/ty_iot_wr_qr_sdk/1.0.3）
I chose Linux 64 bit, and the program compiled by it runs on this machine
