Hi All, I am using boost thread for my project. I have used BCP tool to extract only those binaries that is related to boost thread(and the dependencies also).... Now I am trying to compile my code using only that thread binaries.. previously i tried using that binaries by writing a small code.... and it worked properly. I have done the necessary setings changes in VS2008. A snippet of the errors are as follows c:\program files\bthread\boost\shared_ptr.hpp(142) : error C2332: 'class' : missing tag name 1>c:\program files\bthread\boost\shared_ptr.hpp(142) : error C2011: '<unnamed-tag>' : 'enum' type redefinition 1> c:\program files\microsoft sdks\windows\v6.0a\include\shlwapi.h(1550) : see declaration of '<unnamed-tag>' 1>c:\program files\bthread\boost\shared_ptr.hpp(142) : error C2143: syntax error : missing ',' before 'return' 1>c:\program files\bthread\boost\shared_ptr.hpp(146) : error C2332: 'class' : missing tag name 1>c:\program files\bthread\boost\shared_ptr.hpp(146) : error C2011: '<unnamed-tag>' : 'enum' type redefinition 1> c:\program files\microsoft sdks\windows\v6.0a\include\shlwapi.h(1550) : see declaration of '<unnamed-tag>' 1>c:\program files\bthread\boost\shared_ptr.hpp(146) : error C2143: syntax error : missing ',' before 'return' 1>c:\program files\bthread\boost\shared_ptr.hpp(146) : error C2059: syntax error : 'return' 1>c:\program files\bthread\boost\shared_ptr.hpp(147) : error C2143: syntax error : missing ';' before '{' 1>c:\program files\bthread\boost\shared_ptr.hpp(149) : error C2143: syntax error : missing ';' before '}' 1>c:\program files\bthread\boost\shared_ptr.hpp(153) : error C2143: syntax error : missing ';' before '}' 1>c:\program files\bthread\boost\shared_ptr.hpp(164) : error C2649: 'typename' : is not a 'class' 1>c:\program files\bthread\boost\shared_ptr.hpp(529) : error C2649: 'typename' : is not a 'class' I have done a little bit of googling... but i am not getting the right info.... As we can see it is giving syntax error related to .hpp files .... which I haven't change at all.... I will really appreciate if any body can throw some light on it.... Thanks in Advance Ayan.
