Hi,

I get this warning

yywcsskp.obj : warning LNK4221: no public symbols found; archive member
will be inaccessible

when I compile a static library with VS2005. But the same project with
VS2003 doesn't give this warning.

And this warning seem to cause me problem when I want to link an
application with this library. I got some unresolved external symbol
like this

my_lexer.obj : error LNK2001: unresolved external symbol "public:
virtual void __thiscall yl::yywlexer::yyerror(unsigned short const *)"
(?yyerror@yywlexer@yl@@UAEXPBG@Z)

Can somebody help me ? Is it a VS2005 known bug ?

It's likely the result of fixing a bug in 2003, but since you haven't posted
any code, it's impossible to know for sure.

How is yl::yywlexer::yyerror declared? How is the class yl::yywlexer
declared?

and why the size of the generated library is very different between
VS2005 and VS2003 ?

2,418 KB (VS2005) vs 1,679 KB (VS2003)

Probably larger symbol information in the 2005 library. The code itself
shouldn't be larger unless it's a debug build - the 2005 compiler includes
more runtime checks in debug builds than 2003 did.
