Compiling Target

Only Once:

(Do this if you still don't have Makefile.in). In behavioural-model/configure.ac:
Under Generate makefiles:

• targets/P4-SAI/Makefile
• targets/P4-SAI/tests/Makefile
• targets/P4-SAI/tests/CLI_tests/Makefile

Under Generate Other files

• AC_CONFIG_FILES([targets/P4-SAI/tests/CLI_tests/run_one_test.py], [chmod +x targets/P4-SAI/tests/CLI_tests/run_one_test.py])

In behaviooural-model/targets folder/Makefile.am:

• add P4-SAI to SUBDIRS variable.

now execute in behavioural-model/ folder:

• ./autogen.sh
• ./configure
• make

Changes only in target:

For every change in simple_switch.cpp target only needed to do:
execute make in repositor directory.

Compiling P4 to JSON

make sure you have the p4c-bm compiler installed. run p4c-bmv2 --p4-v1.1 --json sai.json --pd PD p4src/sai.p4 on main directory.
