I have read the tool's source code as Prof. Brandenburg instruct, I programmed a small code on file called "base_task.c" in LITMUSRT platform and I wrote the following command line( I attached a picture for the command and other commands):

Dear Marov,

the tool is behaving as expected. It does not make sense to feed a file containing C source code to a tool expecting a device file.  I suggest you review the differences between interpreters and compilers, source files and compiled executables, and device files on Unix-like platforms. This is basic knowledge that we cannot help you with here.
