Hi,

 

I received this message for both libboost_regex.a and libboost_date_time.a.  I then recompiled only the regex library back to version 56.  The following is the result:

 

c++ by_bld.cpp \

/usr/local/lib/libboost_system.a \

/usr/local/lib/libboost_regex.a \

/usr/local/lib/libboost_date_time.a

/usr/local/lib/libboost_date_time.a(greg_month.o):greg_month.cpp:(.text+0x4fb): undefined reference to `__dso_handle'

/usr/local/lib/libboost_date_time.a(greg_month.o):greg_month.cpp:(.text.startup+0x13): undefined reference to `__dso_handle'

collect2: error: ld returned 1 exit status

Makefile:2: recipe for target 'by_bld' failed

make: *** [by_bld] Error 1

 

What gives with version 57?  Since then I have compiled the date_time library back to version 56 and it works (I will be moving to chrono eventually…).

 

Thanks,

Steve Valentine
