Hi Buddy: I down the boost 1.3.3.1 and stlport 4.6.2 and then using the command < bjam.exe -sTOOLS=msvc-stlport -sSTLPORT_4.6.2_PATH=D:\SDK\Stlport\STLport-4.6.2 > to build the boost source ,but some error was threw out in compile process just as: E:\boost_1_33_1\boost/date_time/date_formatting.hpp(64) : fatal error C1001: INT ERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information I searched the web and find out some clues at microsoft web site http://support.microsoft.com/kb/226110/en-us and Microsoft has comfirmed that this is a bug of vc6 . But I'm thinking if there is any other way to build the boost with stlport . If anyone knows it,please give me a tip! Thank you very much! Hongquan I-ZQ
