Hello everyone：

When I compiled this model using MinGW64, a fault occurred, with the following information:

### Starting build procedure for: TestLinUnpack ### Generating code and artifacts to 'Model specific' folder structure ### Generating code into build folder: E:\Test_LINUNPACK\TestLinUnpack_ert_rtw ### Invoking Target Language Compiler on TestLinUnpack.rtw ### Using System Target File: D:\matlab2022b\rtw\c\ert\ert.tlc ### Loading TLC function libraries ### Generating TLC interface API for custom data ### Initial pass through model to cache user defined code . ### Caching model source code ### Writing header file TestLinUnpack_types.h . ### Writing header file TestLinUnpack.h ### Writing header file rtwtypes.h ### Writing source file TestLinUnpack.c ### Writing header file TestLinUnpack_private.h ### Writing source file TestLinUnpack_data.c . ### Writing source file ert_main.c ### TLC code generation complete (took 3.603s). ### Saving binary information cache. ### Using toolchain: MinGW64 | gmake (64-bit Windows)

How can I solve this problem?The attached is the model file and ldf file.

Thank you!
