error in memoir: Command \newfloat already defined

Question

Using this preamble:

\documentclass[pdftex,11pt,a4paper,openany]{memoir}
\usepackage[brazil]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{indentfirst}
\usepackage{latexsym}
\usepackage{amsmath,amssymb,amsfonts,wasysym}
\usepackage[pdftex]{graphicx}
\usepackage{wrapfig}
\usepackage[left=3cm,right=2cm,top=3cm,bottom=3cm]{geometry}
\usepackage{color}
\usepackage[dvipsnames]{xcolor}
\definecolor{darkgray}{gray}{0.3}
\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}
\usepackage[pdftex, colorlinks=true, linkcolor=darkgray, citecolor=blue, urlcolor=blue]{hyperref}

TexMaker gives this error message:

! LaTeX Error: Command \newfloat already defined.
Or name \end... illegal, see p.192 of the manual.

Where is the problem?

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces, then they are marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). — Caramdir, Jul 21 '11 at 17:49
There's no error with the preamble you provided. If you are trying to load the package float afterwards, don't: memoir has its built-in mechanism for this. Never use the option pdftex. — egreg, Jul 21 '11 at 18:04
no, just that there is no reason to specify the pdftex option. Packages that respond to it will detect it by themselfs — daleif, Jul 21 '11 at 18:51

Just for the record, I had the same problem, using memoir and floatrow together. Removing pdflatex from the preamble did not solve it.

I compiled the document successfully by adding the following line before loading floatrow:

\let\newfloat\undefined
\usepackage{floatrow}

Thanks to Joseph Wright.

There's no error with the preamble you provided. If you are trying to load the package float afterwards, don't: memoir has its built-in mechanism for defining new floating environments.

See p. 169 in the documentation.
