Sorry for the late reply! I successfully reproduced your compilation errors. I fixed the deprecated function call in my recent commit, however, it does not fix the whole compilation issue. One of my colleges will answer this issue in detail soon.

Please check and see if the following examples are working for you: portfwd-gen.p4, l2wfd-gen.p4, l3fwd-wo-chksm-gen.p4. These are our most tested examples and should work well.
