Description
I'm trying to use your regex class. I'm using boost_1_27_0 on Solaris compiled with Workshop 6 update 1. The build of the sample site :http://www.boost.org/libs/regex/example/snippets/ regex_match_example.cpp //THE SAMPLE START { #include <stdio.h> #include <boost/regex.hpp> using namespace std; using namespace boost; #define CHAR char void main() { char *format = "(.*)"; regex expression(format, regbase :: normal, a ); } //SAMPLE FINISHED is failed with the following error: $CC -g - I/usr/mwdata/users/olga/boost_1_27_0 /usr/mwdata/users/ olga/boost_1_27_0/libs/regex/build/sunpro/libboost_rege x_mt.so test.C -o test // ERROR START Undefined first referenced symbol in file boost::detail::allocator<unsigned char>::allocator<char>#Nvariant 1(const boost::detail::allocator<__type_1>&) /vobs/studio/serve r/debugger/SunWS_cache/CC_obj_h/hKZggW9H89qzPd1td_2e.o ld: fatal: Symbol referencing errors. No output written to test/test1 // ERROR FINISHED I have found that the problem comming from the expression initialization line: regex expression("^([0-9]+)(\\-| |$)(.*)$"); regex was defined as "typedef reg_expression < CHAR , regex_traits < CHAR > , :: boost :: detail :: allocator < CHAR > > regex" and the problem is in allocator initialization. If I put the only line with allocator initialization into the sample like: //THE SAMPLE START { #include <stdio.h> #include <boost/regex.hpp> using namespace std; using namespace boost; #define CHAR char void main() { char *format = "(.*)"; :: boost :: detail :: allocator < char> a; } //SAMPLE FINISHED the build is failed with the same error. How could I save this problem with 'Undefined symbol'???
