c++ - In boost::posix_time, how to construct time_duration from volatile time_duration? -


i'm trying compile code:

#include <boost/date_time.hpp> using boost::posix_time::time_duration; int main() {   volatile time_duration t0;   time_duration t1 = t0;   return 0; }

with command:

g++ test01.cpp -std=c++11 -i /boost_1_55_0/ -o test01

and error:

test01.cpp:6:22: error: no matching function call ‘boost::posix_time::time_duration::time_duration(volatile boost::posix_time::time_duration&)

i'm using gcc 4.8.2; idea how fix this?

this due a gcc bug. workaround so:

volatile time_duration t0; time_duration t1 = const_cast<time_duration&>(t0);

it works because const_cast can remove volatility constness. i'm not sure how strictly safe is, mind you.

an alternative fix rid of volatile in first place; serves purpose nowadays.
