Hi Shawn, I've never compiled using HP's compiler, so take this for what its worth....

I suspect its because x86 is very tolerant of misaligned data, so the flag was never needed to preempt the SIGBUS that could result. > "misc.h", line 414: warning #2186-D: pointless comparison of unsigned > integer > with zero > if (a < 0) > ^ > detected during instantiation of "std::string > CryptoPP::IntToString(T, unsigned int) [with T=unsigned > long]" at line 35 of "simple.h" > This is due to an unsigned type with template code. It works fine with signed types. template <class T> Foo<T>::someMethod(T t) { if(t < 0) .... } For GCC, you can suppress the warning with -Wno-type-limits. Under Clang, you would use -Wno-tautological-compare. I'm not sure what you would use under HP's compiler. > shark.cpp > "secblock.h", line 39: warning #4276-D: relational operator ">" always > evaluates to 'false' > if (n > ~size_t(0) / sizeof(T)) > ^ I'm not sure what to do here since I've never encountered it. Perhaps a template specialization while removing the offending code? > "seckey.h", line 50: warning #4276-D: relational operator ">" always > evaluates > to 'false' > if (rounds < MIN_ROUNDS || rounds > MAX_ROUNDS) > ^ Ditto. You should see a lot of these (MIN_ROUNDS, BLOCKSIZE, DEFAULT_KEYLENGTH, ...) since they are enumerations and static constants.
