Config problem / initial setup
Here's what will probably be a really easy question (hopefully it is not too far off topic). I'm trying to get Boost installed on my machine, but I haven't been able to get a working program yet. I downloaded the "bjam" program and the source for the libraries. Performing the 'bjam "-sTOOLS=gcc" install' as recommended by the "Getting Started Guide" seemed to run smoothly. (and I can't find any logs in the build directory which which would tell me differently). So next I tried to compile an example program from Regex... http://www.boost.org/libs/regex/example/snippets/credit_card_example.cpp ...this initially failed with a message complaining about "boost/regex.hpp" not being found. So I added an additional include search path... g++ -I /usr/local/include/boost-1_33_1/ credit_card_example.cpp ...this works fine until the linker gets invoked...
/tmp/ccagNJn9.o(.gnu.linkonce.t._ZN5boost11regex_matchIN9__gnu_cxx17__ : undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__ collect2: ld returned 1 exit status
...etc. So it looks like it can't find the libraries to link against. But my /usr/local/lib directory has all sorts of libboost* files, including libboost_regex-gcc.so and friends. I've tried a number of other g++ options including "-lboost", "-llibboost", "-llibboost_regex", and "-llibboost_regex-gcc". Any hints on what I might try to get things up and running? My system is Slackware Linux 9.1 and gcc 3.4.2. Thanks, Greg Buchholz

Try adding "-lboost_regex-gcc", the "lib" prefix is added for you by the linker. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org

Ah, thanks, that did the trick! Greg Buchholz

That would be -lboost_regex-gcc, but see the getting started guide for more information on how different build variants get named. John.
