HP-UX 11.11 C-ANSI-C has no stdint.h

[Tux]

By the time these archaic systems were still modern, stdint.h did not exist on HP-UX

I created src/ltm/stdint.h:

#define MP_32BIT

(MP_64BIT caused epic failures)

HP-UX 11.11/64 U  rp3410/64 PA8800/800
This is perl 5, version 14, subversion 2 (v5.14.2) built for PA-RISC2.0-LP64

With above define, I saw

All tests successful.

on HP-UX 11.31 building with HP C-ANSI-C in 64bitall mode, I needed

#define MP_64BIT

and

wgrep __hpux src/ltm/tommath.h
src/ltm/tommath.h:   90 ===
#      error You must not define DIGIT_BIT when using MP_16BIT
#   endif
#elif defined(MP_64BIT)
/* for GCC only on supported platforms */
typedef uint64_t mp_digit;
#   if defined(__GNUC__) || defined(__hpux)
typedef unsigned long        mp_word __attribute__((mode(TI)));
#   else
/* it seems you have a problem
 * but we assume you can somewhere define your own uint128_t */
typedef uint128_t            mp_word;

Furthermore, the #defines in ltc/headers/tomcrypt_custom.h are not dynamic, causing havoc if methods are not available. ON this system I had to #undef LTC_RC4, LTC_CHACHA20, LTC_YARROW, LTC_FORTUNA, and LTC_SOBER128, after which all tests fail :(

Hi I have still an access to p5p-hpux.procura.nl (you have granted to me) can I reproduce it there?

Ad stdint.h do you know of any handy #ifdef to detect the situation when we do not have stdint.h on HP/UX?

[Tux]

You still have access to that box. However, it is a PA-RISC2 , not a Itanium.
I hope to be able to add Itanium to that network segment, but I need the management to grant me an oké, as they don't want to pay for the electricity

[Tux]

FWIW I need CryptX for Spreadsheet::ParseXLSX, which I use a lot.

[karel-m]

I have just uploaded CryptX-0.060_001 can you test it?

It looks like the compiler does not like a struct containing an anonymous union like:

typedef struct {
   union {
      char dummy[1];
      struct yarrow_prng    yarrow;
      struct rc4_prng       rc4;
      struct chacha20_prng  chacha;
      struct fortuna_prng   fortuna;
      struct sober128_prng  sober128;
   };
   short ready;
} prng_state;

"Anonymous unions are a GNU extension, not part of any standard version of the C language. You can use -std=gnu99 or something like that for c99+GNU extensions, but it's best to write proper C and not rely on extensions which provide nothing but syntactic sugar...

Edit: Anonymous unions were added in C11, so they are now a standard part of the language. Presumably GCC's -std=c11 lets you use them."
Added in gcc-2.95: https://gcc.gnu.org/ml/gcc-patches/1999-06n/msg00376.html

Surprisingly, AIX' xlc accepts this code style.
Note that perl itself requires C89 (not even C99), so declaring C11 should not be an option IMHO.

@sjaeckel what do you think about this libtomcrypt related change to avoid the use of anonymous union e038ed0 ?

[karel-m]

@Tux could you try http://cpan.metacpan.org/authors/id/M/MI/MIK/CryptX-0.060_002.tar.gz ?

[karel-m]

@sjaeckel or do you prefer an alternative approach proposed by @Tux c5a9061 ?

[Tux]

@karel-m @sjaeckel Karel's patch also works fine:

@sjaeckel ping - c5a9061 or e038ed0 ?
