Hi, I am totally new to boost and just wanted to ask a couple of simple questions... First, I compiled the boost libraries okay with msvc. I updated the include path in my vc++ 6.0, and can include boost files via #include <boost/xxx.hpp>. So far so good! I wanted to try some things out, like boost's mersenne twister random number generator. I first did this: #include <boost/random/mersenn_twister.hpp> And got no errors. Then I read there was a random.hpp for convenience so I changed this to: #include <boost/random.hpp> And received as a reward complaints: d:\dev\devproject\boost_1_30_0\boost\random\uniform_01.hpp(44) : error C2275: 'std::numeric_limits<`template-parameter258'>::is_integer' : illegal use of this type as an expression d:\dev\devproject\boost_1_30_0\boost\random\uniform_01.hpp(95) : see reference to class template instantiation 'boost::uniform_01<UniformRandomNumberGenerator,RealType>' being compiled There were 6 of these errors. What am I doing wrong? Also, is there a way to include the boost libs in vc++ where I get the autocompletion if I use boost:: ? It is very difficult to figure out how the libs are supposed to be used (for me) by looking at example code or the documentation. Autocompletion as if boost were part of my project would be very useful. Thanks, B
