Probably same issue https://github.com/p0pr0ck5/lua-resty-waf/issues/303

I tried luarocks install lua-resty-waf CC=gcc-5 but I get error agan.

gcc-5 -Wall -O3 -flto -g -fPIC -MMD -Wl,--build-id -DBUILDING_SO -c entities.c
make[1]: gcc-5: Command not found

addition, your #303 Patched and then make && make install It works fine
