I've started to play with this after starting to read the (nice) docs.
But I've come to a sudden halt on the "Hello World" :-(
Running it without has produced the (expected) warning that I haven't built the library yet)
LINK : fatal error LNK1104: cannot open file 'libboost_chrono-vc100-mt-gd-1_45.lib'
Assuming I could just try it out as header only first, (before I begin swearing at bjam ;-)
I've added
#define BOOST_CHRONO_INLINED
// run_timer_example.cpp ---------------------------------------------------//
#define BOOST_CHRONO_INLINED
#include <boost/chrono/process_times.hpp> #include <cmath> ...
But got a surprising list of errors:
C:\Program Files\Microsoft SDKs\Windows\v7.0A\include\driverspecs.h(142): error C2008: '$' : unexpected in macro definition C:\Program Files\Microsoft SDKs\Windows\v7.0A\include\driverspecs.h(294): error C2008: '$' : unexpected in macro definition C:\Program Files\Microsoft SDKs\Windows\v7.0A\include\driverspecs.h(295): warning C4005: '__' : macro redefinition
What am I doing wrong?
Hi, currently Boost.Chrono in a header only library if Boosy.System it is also. You need have you defined BOOST_SYSTEM_INLINED? When I remove the BOOST_SYSTEM_INLINED I get the expected error: run_timer_example.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAABVerror_category@12@XZ) referenced in function "public: __thiscall boost::system::error_code::error_code(void)" (??0error_code@system@boost@@QAE@XZ) On cygwin I get the following $ g++ -I /boost/v44 ../example/run_timer_example.cpp -D BOOST_CHRONO_INLINED -D BOOST_SYSTEM_INLINED Vicente@viboes1 /boost/v44/libs/chrono/test $ ./a.exe real 0.015s, cpu 0.000s (0.0%), user 0.000s, system 0.000s Could you sent the command line you used? Best, Vicente
