HI,

please could you check the boost/chrono/config.hpp file.

It contains the following 

# if defined( BOOST_CHRONO_WINDOWS_API )
#   ifndef UNDER_CE
#     define BOOST_CHRONO_HAS_PROCESS_CLOCKS
#   endif
#   define BOOST_CHRONO_HAS_CLOCK_STEADY
#   define BOOST_CHRONO_HAS_THREAD_CLOCK
#   define BOOST_CHRONO_THREAD_CLOCK_IS_STEADY true
# endif

# if defined( BOOST_CHRONO_MAC_API )
#   define BOOST_CHRONO_HAS_PROCESS_CLOCKS
#   define BOOST_CHRONO_HAS_CLOCK_STEADY
#   define BOOST_CHRONO_THREAD_CLOCK_IS_STEADY true
# endif

# if defined( BOOST_CHRONO_POSIX_API )
#   define BOOST_CHRONO_HAS_PROCESS_CLOCKS
#   include <time.h>  //to check for CLOCK_REALTIME and CLOCK_MONOTONIC and _POSIX_THREAD_CPUTIME
#   if defined(CLOCK_MONOTONIC)
#      define BOOST_CHRONO_HAS_CLOCK_STEADY
#   endif

Does your platform meets the condition for which BOOST_CHRONO_HAS_CLOCK_STEADY is defined?

comment:5 by gengyonghui@…, 9 years ago

I tested the micro, it is NOT defined under hp-ux ia 11.23, hp-ux pa 11.11, and solaris 8/9. But is defined under AIX 5.2.

$uname -a HP-UX machinename B.11.23 U ia64 unlimited-user license

$cat micro.cpp #include <string> #include <iostream> #include <stdio.h> #include <stdlib.h> #include <boost/chrono/config.hpp> using namespace std;

int main() { #ifdef BOOST_CHRONO_HAS_CLOCK_STEADY

printf("boost_chrono_has_clock_steady is defined!\n");

#else

printf("boost_chrono_has_clock_steady is not defined!\n");

#endif

return 0;

}

$g++ -Iboost_1_55_0 -o micro micro.cpp

$./micro boost_chrono_has_clock_steady is not defined!

Thanks.

comment:6 by viboes, 9 years ago

I was requesting you to analyze why it is not defined. It is because CLOCK_MONOTONIC is not defined? If yes, could you find if there is something like that?

Hi Viboes, You are right, CLOCK_MONOTONIC is not defined. I have attached /usr/include/time.h and /usr/include/sys/time.h files. Thanks.

Resolution: worksforme
Status: closed → reopened

I have the same issue on HP/UX. CLOCK_MONOTONIC is not available on HP/UX. I suppose CLOCK_REALTIME would be a non-optimal fallback. However, there is a gethrtime() function that returns a similar value to clock_gettime(CLOCK_MONOTONIC), also measured in nanoseconds:

typedef int64_t hrtime_t;

hrtime_t gethrtime(void);

comment:11 by viboes, 8 years ago

Please, could you provide a patch, I'm unable to test it, so unable to write it.

comment:12 by 20313412@…, 8 years ago

Hi Viboes，I have the same issue too. Could you please provide a patch? Or any suggestion/workaround to resolve this issue? I'll follow your suggestion to write a patch and verify the patch in our environment as soon as possible .

comment:13 by 20313412@…, 8 years ago

My email address 20313412@…, anyone knows how to fix this issue please mail me.

comment:14 by viboes, 8 years ago

Ok. I will create a branch to take care of this issue. I will add code as soon as I know what to put in. I would need that you check this branch on your environment.

We can start by identifying under which conditions gethrtime is available. Try something like that and tell me what to put in WHATEVER_HPUX_SPECIFIC_FLAG_ENSURES_GETHRTIME_WILL_BE_DEFINED.

Maybe this will help you to find out the flag 

This API will only be available if the application is being compiled in -Ae mode 
(extended ANSI) because 64-bit integer numbers are not available in -Aa (ANSI) mode. 
Please refer to cc(1).

comment:18 by viboes, 8 years ago

Yet an additional commit

Added the possibility for the user to define BOOST_CHRONO_HAS_GETHRTIME and manage with error cases

​https://github.com/boostorg/chrono/commit/b06da09faaa0ee55e991695e81b7320bdaf4e6e6

Please, define BOOST_CHRONO_HAS_GETHRTIME on your build system to see if the patch works.

If this is the case, the last thing to find are the flag for WHATEVER_HPUX_SPECIFIC_FLAG_ENSURES_GETHRTIME_WILL_BE_DEFINED.

comment:19 by 20313412@…, 8 years ago

Hi Viboes, what a quick response!

My test environment: HP-UX B.11.23 ia64, gcc 4.7.1, boost 1.53 and boost 1.57

my findings:

  1. there's no header file named user_time.h on hp-ux
  2. I didn't find any flag(in time.h) which controls the availability of function gethrtime, just use this function directly and everything works fine( or please kindly tell me how to find the Flag that you want);
  3. with some modification based on your patch, the bug is verified to be fixed!!!!
  4. please kindly let me know if you want any operation/verification under HP-UX, I'd like to do that.

Please, add only the changes, not the whole file. Post here the changes you want respect to what I is already in the last version of the fix branch.

I wan not say that we have always gethrtime() as the documentation says 

This API will only be available if the application is being compiled in -Ae mode 
(extended ANSI) because 64-bit integer numbers are not available in -Aa (ANSI) mode. 
Please refer to cc(1).

I would need a flag that states if the user compiles with option -Ae.

The following 

#   elif (defined(__HP_aCC) || defined(__GNUC__)) && defined(__hpux)

is equivalent to my 

# if BOOST_PLATFORM="HP-UX"

Isn't it?

comment:24 by viboes, 8 years ago

Thanks for the diff and the test. Fixed the missing right-parenthesis ). Removed include user_time.h.

​https://github.com/boostorg/chrono/commit/7f817fe8c1a4b0e336e627fa658323e27facc39a

Yet missing the flag. I could merge this to develop as it works. The single thing the user must do is to define BOOST_CHRONO_HAS_GETHRTIME. This can be documented.

What do you think?

comment:26 by 20313412@…, 8 years ago

Hi Viboes, checked HP-UX with following code: 

#include </usr/include/time.h>
int main()
{
    
  #ifdef _POSIX_SOURCE
    long long a = 0;
    a += 1;
    
    hrtime_t begin ;
    begin = gethrtime(); 
  #endif
  return 0;    
    
}

both following cmd line successed 

cc -g -Ae -o b b.c

cc -g -Aa -o b b.c

with following code 

#include </usr/include/time.h>
int main()
{
    long long a = 0;
    a += 1;
    
    hrtime_t begin ;
    begin = gethrtime(); 
  return 0;    
    
}

failed to compile with cc -g -Aa -o b b.c err msg: 

"b.c", line 4: warning #2450-D: the type "long long" is nonstandard
      long long a = 0;
           ^
"b.c", line 7: error #2268: declaration may not appear after executable
          statement in block
      hrtime_t begin ;
      ^
"b.c", line 7: error #2020: identifier "hrtime_t" is undefined
      hrtime_t begin ;
      ^
2 errors detected in the compilation of "b.c".

but successed with cc -g -Ae -o b b.c

so , I think:

  1. BOOST_NO_LONG_LONG indicates no -Ae option used in cmd line
  2. _POSIX_SOURCE indicates -Ae model too
  3. since {{{In HP-UX 10.20 and earlier releases, compatibility mode is the default

compilation mode. In HP-UX 10.30 forward, extended ANSI mode (-Ae) is the default}}}, maybe it's not necessary to check -Ae model?

I think about just checking the version, however the default is not forcedly what the user uses ;-)

Patch for tocket 9379

comment:30 by brian.groose@…, 5 years ago

I know this has been resolved as wontfix, but if there's any chance of this getting fixed, that would be great. I have attached a patch that fixes this for g++ on HPUX, based on previous patches attached and references in this bug. I did not test with aCC since I do not use it.
