Hi all, Sorry for the repeated noise on this one, but I haven't had a reply (apart from Hartmut who pointed me in the right direction to the solution). At the moment, there are two problems with: bjam install msvc-7.1 link=static,shared (1) The <rtti> feature isn't included in <tag> names, so Boost.Wave/FileSystem produce duplicate target errors. (2) The <link>shared feature generates a LIB target that clashes with the LIB from <link>static, again producing duplicate target errors. This needs fixing for 1.34.0! I have attached a patch that fixes the problem, but I would like to know that this is the right fix and that I haven't missed anything obvious. For issue (1), I am adding an 'r' for rtti=on. Given: bjam install msvc-7.1 rtti=on this will produce: boost_filesystem-vc7_1-gd-r.lib boost_filesystem-vc7_1-gd.lib boost_wave-vc7_1-gd.lib For issue (2) I am now adding an 'i' instead of '-imp' for the import LIB files. Given: bjam install msvc-7.1 link=static,shared this will produce: boost_filesystem-vc7_1-gd-r.lib boost_filesystem-vc7_1-gd-ir.lib boost_filesystem-vc7_1-gd-r.dll - Reece _________________________________________________________________ Try Live.com: where your online world comes together - with news, sports, weather, and much more. http://www.live.com/getstarted
