Well I'm rather puzzelled why you're the only person to be experiencing this... I've tried to locate a binary version of gcc-3.3 to test with but couldn't find one for my Linux box - is there any way you can use a newer gcc release as 3.3 is rather old these days? Alternatively what happens if you build the application and the regex source all together like this: g++ -O3 test.cpp boost-path/libs/regex/src/*.cpp or if that fails then like this: g++ -O3 -DBOOST_REGEX_NO_EXTERNAL_TEMPLATES=1 test.cpp boost-path/libs/regex/src/*.cpp ?
