Boost Date_Time problem compiling a simple program
- by Andry
Hello!
I'm writing a very stupid program using Boost Date_Time library.
int main(int srgc, char** argv) {
using namespace boost::posix_time;
date d(2002,Feb,1); //an arbitrary date
ptime t1(d, hours(5)+nanosec(100)); //date + time of day offset
ptime t2 = t1 - minutes(4)+seconds(2);
ptime now = second_clock::local_time(); //use the clock
date today = now.date(); //Get the date part out of the time
}
Well I cannot compile it, compiler does not recognize a type...
Well I used many features of Boost libs like serialization and more... I correctly built them and, looking in my /usr/local/lib folder I can see that libboost_date_time.so is there (a good sign which means I was able to build that library)
When I compile I write the following:
g++ -lboost_date_time main.cpp
But the errors it showed me when I specify the lib are the same of those ones where I do not specify any lib.
What is this? Anyone knows?
The error is
main.cpp: In function ‘int main(int,
char**)’: main.cpp:9: error: ‘date’
was not declared in this scope
main.cpp:9: error: expected ‘;’ before
‘d’ main.cpp:10: error: ‘d’ was not
declared in this scope main.cpp:10:
error: ‘nanosec’ was not declared in
this scope main.cpp:13: error:
expected ‘;’ before ‘today’
