I want to use the package makeidx, but I can't.
When I comment out the usepackage{makeidx} everything is ok, but I don't have index at the end.

Note

index{animal} at the end.

I have this source

documentclass{article}

usepackage{amsmath,amssymb}

%usepackage[fleqn]{amsmath}

usepackage{stmaryrd}



usepackage{makeidx}



DeclareMathAlphabetEuScript{U}{eus}{m}{n}

SetMathAlphabetEuScript{bold}{U}{eus}{b}{n}

newcommand{CMcal}{}

letCMcal=mathcal

usepackage{fancybox}

usepackage{shadow}



usepackage{carom,epic,eepic,hetarom}



usepackage{xymtexpdf}%%PDF-compatible mode

%usepackage{xymtexps}%%PostScript-compatible mode

%wedgehashedwedge%global declaration







begin{document}

cyclohexanev{2B==Cl;4E==S}

X shadowbox{This is a shadowbox}

Y shabox{This is a shabox} Z



cyclohexanev{}

cyclohexanev{ 1==1 ; %

2D==2D ; %

3A==3A ; %

4B==4B ; %

5Sa==5Sa ; 5Sb==5Sb ; %

6SA==6SA ; 6SB==6SB}



index{animal}





$bigcurlyvee$



[ mathcal{A} = EuScript{A} neq CMcal{A} ]

begin{theindex}

end{theindex}



end{document}
