Hello World,
I'm doing some experiments to use boost (1.33.1) under Win XP and with
MinGW (5.1.3) environment. Boost was compiled with bjam with no
particular options.
I'm facing some problems on linking with boost_date_time. Here is the
simple test program:
#include <iostream>
#include <string>
#include
using namespace std;
using namespace boost::posix_time;
int main (int argc, char** argv)
{
char dummy;
ptime d1(min_date_time);
ptime d2(max_date_time);
cout << "min:" << to_simple_string(d1) << endl;
cout << "max:" << to_simple_string(d2) << endl;
cin.get(dummy);
return 0;
}
Compiling lines are :
g++ -DUSE_DATE_TIME_PRE_1_33_FACET_IO -I"E:\dev\boost_1_33_1" -O0 -g3
-Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o"main.o"
"../main.cpp"
g++ -L"E:\dev\boost_1_33_1\stage\lib" -o"TestBOOST.exe" ./main.o
-lboost_date_time-mgw-mt-d-1_33_1
I get the error (simplified output) :
E:/dev/boost_1_33_1/boost/date_time/gregorian/greg_weekday.hpp:
undefined reference to `boost::gregorian::greg_month::as_long_string()
const'
If I remove the lines with *to_simple_string*, I get no error.
From the docs [*] it seems there may be a problem for streams support
for some compilers, so I tryed to define USE_DATE_TIME_PRE_1_33_FACET_IO
in my project, but with no effect. Does it needs to be done when
compiling boost ?
Is there any other way to solve my link problem ?
(appart not using string output for dates :-) )
Thanks for any help.
