Fix build warnings with recent boost libraries (>= 1.67) #118

Closed myungjoo closed 4 years ago

myungjoo commented 4 years ago

With https://github.com/boostorg/date_time/commit/f9f2aaf5216c we need to update the usage of duration. Reference: https://github.com/Icinga/icinga2/pull/6230

Can you please provide more details about your exact environment as well as the specific error message you are seeing?

I can build the current state of the target branch just fine on Ubuntu Focal which has Boost 1.67.0 - same for the buildfarm which has built the package as well as downstream packages using it just fine.

I'm using gcc-9 with strict build options that do not ignore warnings.

gcc-c++-9.2.0 glibc-devel-2.30 boost-devel-1.71

I believe this is related with GCC-9 + Boost-recent because this code was ok with GCC-6 + Boost-a--bit-old.

The Jenkins job doesn't show any compiler warnings: http://build.ros.org/view/Ndev/job/Ndev__roscpp_core__ubuntu_focal_amd64/6/

Can you please show the exact compiler warning you see with the latest state of the targeted branch (noetic-devel)?

Also you error message shows kinetic which isn't the targeted branch of this patch.
