#9379: 'boost::chrono::steady_clock' has not been declared" on boost 1.55, hp-ux
11.23 IA, gcc 4.6
-------------------------------+--------------------------
Reporter: gengyonghui@… | Owner: viboes
Type: Bugs | Status: reopened
Milestone: To Be Determined | Component: chrono
Version: Boost 1.55.0 | Severity: Problem
Resolution: | Keywords: steady_clock
-------------------------------+--------------------------
Comment (by 20313412@…):
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.
