Unzipping Zip file in EC600U Module

I am trying to unzip Zip file in EC600U module using openQuec(openCPU). I am encountering error as undefined reference to `ql_fs_unzip’

Screenshot is attatched below:

Kindly help in resolving this issue or by suggesting alternative to `ql_fs_unzip’, because it is not working.

the solution to this is to enable Zip File handler in the SDK by appending following line:

CONFIG_QUEC_PROJECT_FEATURE_FILE_ZIP=y
in the components\ql-config\build\EC600UCE_AC\8915DM_cat1_open\target.config
