‘.sdnet_switch_info.dat’ Does not Exist.

Hello, I am a freshman in P4->NetFPGA. I am trying to compile my code following the Workflow Overview provided in the Wiki of this project.

I set P4_PROJECT_NAME=switch_calc, and go to the directory for compiling.

When I enter make, an error occurs as follows:

p4c-sdnet -o switch_calc.sdnet switch_calc_solution.p4
/home/tian/wbq/P4-NetFPGA/contrib-projects/sume-sdnet-switch/bin/p4_px_tables.py commands.txt .sdnet_switch_info.dat
Traceback (most recent call last):
  File "/home/tian/wbq/P4-NetFPGA/contrib-projects/sume-sdnet-switch/bin/p4_px_tables.py", line 409, in <module>
    main()
  File "/home/tian/wbq/P4-NetFPGA/contrib-projects/sume-sdnet-switch/bin/p4_px_tables.py", line 404, in main
    make_px_tables(args.switch_info_file)
  File "/home/tian/wbq/P4-NetFPGA/contrib-projects/sume-sdnet-switch/bin/p4_px_tables.py", line 225, in make_px_tables
    with open(switch_info_file) as f:
IOError: [Errno 2] No such file or directory: '.sdnet_switch_info.dat'
Makefile:34: recipe for target 'all' failed
make[1]: *** [all] Error 1
make[1]: Leaving directory '/home/tian/wbq/P4-NetFPGA/contrib-projects/sume-sdnet-switch/projects/switch_calc/src'
Makefile:57: recipe for target 'frontend' failed
make: *** [frontend] Error 2

The problem is from the following pieces of code in p4_px_tables.py:

def make_px_tables(switch_info_file):
    with open(switch_info_file) as f:
        switch_info = json.load(f)
    for table_dict in switch_info['lookup_engines']:
        table_name = table_dict['p4_name']
        table_type = table_dict['match_type']
        if (table_type == "EM"):
            PX_TABLES[table_name] = PXCAMTable(table_dict)
        elif (table_type == "TCAM"):
            PX_TABLES[table_name] = PXTCAMTable(table_dict)
        elif (table_type == "LPM"):
            PX_TABLES[table_name] = PXLPMTable(table_dict)
        else:
            print >> sys.stderr, "ERROR: {0} uses an unsupported match type".format(table_name)
            sys.exit(1)

The problem is the missing of file .sdnet_switch_info.dat, which should be placed in the src folder of the switch_cal project. However, it is missing right now.

I have searched the error in Google, but there is not an explanation of this error or related to .sdnet_switch_info.dat file.

These are the environment settings of my PC:

###### Vivado ######
source /home/tian/Xilinx/Vivado/2016.4/settings64.sh

#### P4-NetFPGA #####
source /home/tian/wbq/P4-NetFPGA/tools/settings.sh

#### SDNet ####
source /home/tian/Xilinx/SDNet/2018.1.1/settings64.sh
export PATH=/home/tian/Xilinx/SDNet/2018.1.1/bin:$PATH

# point to Vivado license file and SDNet license file
export XILINXD_LICENSE_FILE=/home/tian/software/license/Xilinx_sdnet.lic

Could you share some ideas on my problem? Thank you for your time. Best wishes.
