Sorry if this is double-posted, but my webmail has stripped angle brackets and 
their contents out of my previous email ... 
 
Boost 1.40 on CentOS 5.3 64bit: 
 
I have #included boost/regex.hpp in a file but get the following compile time 
error (mangled by webmail): 
 
 
/tmp/ccXM0HkR.o: In function `boost::basic_regex 
boost::cpp_regex_traits > >::assign(char const*, char const*, unsigned int)': 
contact.cpp:(.text._ZN5boost11basic_regexIcNS_12regex_traitsIcNS_16cpp_regex_traitsIcEEEEE6assignEPKcS7_j[boost::basic_regex 
boost::regex_traits > >::assign(char const*, 
char const*, unsigned int)]+0x27): undefined reference to 
`boost::basic_regex 
> >::do_assign(char const*, char const*, unsigned int)' 
collect2: ld returned 1 exit status 
 
 
The important bit appears to be 'undefined reference to boost__basic_regex' etc 
 
This file definitely exists at /usr/include/boost/regex.hpp. 
Another Boost #include in the same file 
(boost/date_time/posix_time/posix_time.hpp) produces no error. 
'ldconfig -p' lists libboost_regex.so. 
 
What am I doing wrong? 
 
Thanks 
Mike
