I guess you mean compiling DPDK itself, but I can add that compiling my
example "app" (i.e., a file which includes the DPDK headers and an empty
main()) with clang++ gives more problems:

  include/rte_devargs.h:89:5: error:
      'virtual' can only appear on non-static member functions
                } virtual;
                  ^

and a slew of warnings of the type

  include/rte_byteorder_64.h:45:2: warning:
      'register' storage class specifier is deprecated
[-Wdeprecated-register]
        register uint64_t x = _x;
        ^~~~~~~~~

include/rte_memcpy.h:85:25: warning:
      cast from 'const uint8_t *' (aka 'const unsigned char *') to
      'const __m128i *' increases required alignment from 1 to 16
[-Wcast-align]
        xmm0 = _mm_loadu_si128((const __m128i *)src);
