My current SDK version is release/v2.4
An example would be fine, please reply if any expert can help.
Take a look at this example: Generate Lib Example - SiFli SDK Programming Guide Document
Could you please explain? I installed the Siche SDK (思澈SDK) version 2.4 on Ubuntu, but why does this example package produce a .a extension?
This should not matter; it’s just that different compilation environments generate different files. The GCC environment generates .a files, while if you switch to the ARMCC environment, it should generate .lib files. There should be no issues in usage. You can check the description of file suffixes for different environments in building.py. Alternatively, you can refer to the way other third-party libraries are built.
