Hi I am trying to build a test program that comes with the Genserial library (http://genserial.soureforge.net), which uses boost. I get the following error while linking: test fatal error LNK1104: cannot open file 'libboost_unit_test_framework-vc71-sgd.lib' This library seems to be included because of these lines in one of the cpp files: #include <boost/test/unit_test.hpp> using boost::unit_test_framework::test_suite; I verified that the file does exist in boost\lib however the naming is different, it has a version number suffix to it "libboost_unit_test_framework-vc71-sgd-1_31.lib'" hence the problem with the linker. How do I go about resolving this, short of renaming all the lib files? Thanks Roy --><8---Profound quote snipped by email server--><8---.
