yywrap compilation issue

[Yves de Champlain]

Hi

I'm trying to build lilypond for MacOS X 10.5 and come across this  
error :

rm -f ./out/lexer.dep; DEPENDENCIES_OUTPUT="./out/lexer.dep ./out/ 
lexer.o" g++ -c -Woverloaded-virtual -DHAVE_CONFIG_H  -DNDEBUG -I./ 
include -I./out -I../flower/include -I../flower/./out -I../flower/ 
include  -O2 -finline-functions -pipe -I/opt/local/include -

lexer.o out/lexer.cc
out/lexer.cc:389: error: no ‘int yyFlexLexer::yywrap()’ member  
function declared in class ‘yyFlexLexer’

Here is line 389 from lexer.cc :

int yyFlexLexer::yywrap() { return 1; }

Here is the virtual declaration from FlexerLexer.h :

        virtual int yywrap();

Thanks for any advice
