I have copied the code from How to write Bengali in LaTeX? .

When I paste it in my KILE editor its not working. Even I have inserted it on https://www.writelatex.com/656918hxmjxx#/1381658/
but it is showing compile error. How to solve this?

sudo apt-get install ttf-bengali-fonts

From above I have installed the code.

When I run the problem is showing:

This is the .log file,:

Answer 1

The log file is telling you that polyglossia needs etoolbox to work. You appear to not have etoolbox installed:

! LaTeX Error: File `etoolbox.sty' not found.

Type X to quit or <RETURN> to proceed,

I would take a look at How to install "vanilla" TeXLive on Debian or Ubuntu? to ensure you have a full TeX Live distribution. If you don't mind being several iterations behind the current state of CTAN, you can run

sudo apt-get install texlive-full

to get (mostly) everything. It should at least come with the tools you need to get this document compiling.

Make sure you are compiling with XeLaTeX; pdfTeX has many limitations concerning Unicode. I don't have Kile installed, but this suggestion from the TUG mailing list will be helpful:

Configure Kile -> tools -> new -> create some name -> behaviour like pdflatex -> change command into "xelatex"

---

Also ensure you have the Akaash and Linux Biolinum O fonts installed on your computer.

Arial Unicode MS is installed on OSX:

\documentclass[10pt]{article}
\usepackage{polyglossia}
\setmainlanguage[numerals=Devanagari]{bengali}
\setotherlanguage{english}
\newfontfamily\bengalifont[Script=Bengali]{Arial Unicode MS}

Find out which fonts Aptitude installed for you and use one of those in Arial's place.
