[Agda] install agda

[Michel Levy]

I followed the instructions you gave below. And thanks to you, I was
able to install Agda-2.6.1, but it wasn't easy.
After the command "cabal install", I got the following message:

michel at M1330:~/Agda-2.6.1$ cabal install
Resolving dependencies...
In order, the following would be installed:
dlist-0.8.0.8 (via: aeson-1.4.1.0) (new package)
exceptions-0.10.4 (via: Agda-2.6.1) (new package)

After a very long list of packages to reinstall, I got the message :
cabal: The following packages are likely to be broken by the reinstalls:
Agda-2.5.3
Use --force-reinstalls if you want to install anyway.

I forced the reinstall, which allowed to install all these missing
packages and after a first failure to reinstall Agda-2.6.1 on the
following error

292 of 369] Compiling Agda.TypeChecking.Rewriting.NonLinMatch (
src/full/Agda/TypeChecking/Rewriting/NonLinMatch.hs,
dist/dist-sandbox-a8ebf48f/build/Agda/TypeChecking/Rewriting/NonLinMatch.o )
ghc: out of memory (requested 1048576 bytes)
"cabal: Leaving directory.
cabal: Error: some packages failed to install:

I started again with "cabal install" and this time the installation
seems to be complete. But I don't know how to use it.
And the previous installation is not broken (fortunately) and still
working with emacs. Hence my question: where to find the new
installation in the directory Agda-2.6.1 and how to reinstall the agda
command and the agda mode .
