Hi, I am trying to compile the example from regex_token_iterator.html using the following entries in the Jamroot file. #Jamroot exe readdata : readdata.cpp : <include>/data/cpp/boost/include/boost-1_33_1/ ; install dist : readdata : <location>. ; and im getting a linker error (collect2: ld returned 1 exit status) However all my attempts to specify the external library location failed. For example I have tried to add lib boost_regex : : <file>boost_regex <search>/data/cpp/boost/lib/ ; exe regexexp : regexexp.cpp .//boost_regex ... and many more weird stuff without success. I found something in about site-config.jam in the manual but the example is not very clear to me. Can anyone please help? Eryk
