There is a nice table in the cabal docs that explains how prefix gets used:<br>

For Vista and above C:\Documents and settings\myusername\ is<br>
C:\Users\myusername. The equivalent to $HOME on Windows would be<br>
$USERPROFILE but the syntax of expanding an environment variable is<br>
going to depend on the shell you are using:<br>
<br>
cmd window: cabal install --prefix=%USERPROFILE% --user<br>
PowerShell: cabal install --prefix=${env:USERPROFILE} --user<br>
msys window: cabal install --prefix=$USERPROFILE --user<br>
<br>
Note that msys does define $HOME and it is a different physical path<br>
than $USERPROFILE.<br>

for win32 platform? <br>Where in this case "cabal install" root will be?<br><br><br>
