I built boost_1.36_0 with vs2005, used command "bjam.exe --build-dir="D:\src\boost_1_36_0" --toolset=msvc --build-type=complete stage". Then i built a project using regex, and link error "can not open file "libboost_regex-vc80-mt-gd-1_36.lib" ". I check the stage diretory, found regex libs: libboost_regex-vc80-mt-s-1_36.lib libboost_regex-vc80-mt-s.lib libboost_regex-vc80-mt-sgd-1_36.lib libboost_regex-vc80-mt-sgd.lib libboost_regex-vc80-s-1_36.lib libboost_regex-vc80-s.lib libboost_regex-vc80-sgd-1_36.lib libboost_regex-vc80-sgd.lib There are no "libboost_regex-vc80-mt-gd-1_36.lib" here. How can i get the "libboost_regex-vc80-mt-gd-1_36.lib" ? PS. I have a machine which has vs2005 and vs2008 install, when i built boost on it, it always uses vs2008 to compile. How can i just use vs2005 buiding it? -- Best regards, PangYongQiang
