You need to link to a library to use boost::regex. It looks like you have the choice of debug/release single/multi-threaded, static library only. The "*.a" files are in $BOOST_ROOT/bin/boost/libs/regex directory tree. Laurent AUDIBERT wrote:

Hello I would like ot use g++ to compile a programme which use boost regex To use regex I put this lines in the header of test_expreg.cpp : #include #include

The file compiles fine with this command line : g++ -c test_expreg.cpp -o test_expreg.o

But I can't link : g++ -o test_expreg test_expreg.o Produce error : : undefined reference to `boost::RegEx::RegEx(std::basic_string const&, bool)'

I tried : g++ -o test_expreg test_expreg.o -L/usr/bin -llibboost_regex

And obtained this error : /usr/bin/ld: ne peut trouver -llibboost_regex

Someone could tel me how compile correcly this programme that already compiles well en Microsoft Visual C++ but that I can't compile with g++ on Linux Fecora Core 3

Thanks, Laurent
