Hi, I'm attempting to get the Boost CRC to compile for a TI C6713 DSP. I'm using C6000 Code Gen Tools 6.1.6 which is based on EDG. STL implementation is from Dinkumware. When I include <boost/crc.hpp> I get the following errors: "C:/Program Files/boost_1_37_0/boost/crc.hpp", line 286: error: shift count is too large detected during instantiation of class "boost::detail::high_uint_t<Bits> [with Bits=64U]" at line 433 "C:/Program Files/boost_1_37_0/boost/crc.hpp", line 288: error: shift count is too large detected during instantiation of class "boost::detail::high_uint_t<Bits> [with Bits=64U]" at line 433 I'm new to Boost so I could use some help figuring this out. I looked at crc.hpp and high_uint_t appears to be a structure containing two uint_t types corresponding with the errors. In integer.hpp the uint_t struct does not evaluate long long. On this architecture a long is 48 bits and long long is 64 bits. I've only included the header so why is it trying to instantiate a 64 bit type? Thanks, Mike
