Hi.. there

Hope all are doing well

I'm dealing with the Makefile based project, for which i have created the recipe file

The file architecture of the recipes file is as follows,

|---modem-api
├── files
│   ├── GpioApi.c
│   ├── GpioApi.h
│   ├── main.c
│   ├── Makefile
│   ├── modem.c
│   ├── modem.h
│   └── target_build
│       └── Makefile
└── modem-api_1.0.bb

- During the building the recipe modem-api, all files are fetched and compiled with out any issue
- The aim is to create the shared library called *libmodem.so* which need to install in */usr/lib* directory after the build

*Problem statement

-* During the do_package, it's generating the error message as *OSError: [Errno 40] too much recursions while resolving*

- For the instance, i have share the make file, recipe file and error logs here

- pl. can anyone help me here ?

all comments and suggestions welcome

Thanks

Mahendra
