Hi Math Toolkit developers. (Sending to this list as library is still in development?) If I try and run the tests on SunCC using the following command: /opt/SunStudio12/SUNWspro/bin/CC -o \ build/debug/vendor/boost/libs/math/test/log1p_expm1_test \ -library=stlport4,Crun \ build/debug/vendor/boost/libs/math/test/log1p_expm1_test.o \ -Lbuild/debug/vendor/boost -Lvendor/boost -lboost_regex I get this linker error: Undefined first referenced symbol in file int boost::math::tools::digits<boost::math::concepts::real_concept>() build/debug/vendor/boost/libs/math/test/log1p_expm1_test.o ld: fatal: Symbol referencing errors. No output written to build/debug/vendor/boost/libs/math/test/log1p_expm1_test Has anyone seen this before? What can I do to fix this? Thanks in advance, Sohail
