TL;DR

make install && make test

Scripts to install tools and configurations I use on a daily basis.

To install everything, you need

• nix
• go

e. g. installed from you systems packages manager.

If you want to setup the Haskell environment you need

• ghc <= 8.6.5 (depending on the MAKE_GHC_VERSION in tools/Makefile)
• cabal >=2.4

You can then run

make install-haskell-env

If your distribution is supported, you can run the preparation script, e. g.

sh prepare.alpine

Targets

• install falls back to install-core
• install-core installs packages, which don't require X11 libraries.
• install-gui installs core tools and gui tools
• install-haskell-env installs GHC, cabal and useful development tools.

GHC

GHC_VERSIONS

Depending on the installed GHC version you have to set GHC_VERSIONS. It is recommended to start with the system installed version. The list has to be in ascending order and has to contain 8.6.5 and 8.8.2. Assuming your system has GHC 8.2.2 install you should call make with

make GHC_VERSIONS='8.2.2 8.4.2 8.6.5 8.8.2' install-haskell-env

Customizations

You can specify workstation specific settings in $HOME/local/profile, e. g.

export BROWSER=firefox
export ACME_VARFONT=/mnt/font/FreeSans/12a/font
export ACME_FIXFONT=/mnt/font/DejaVuSansMono/13a/font

Troubleshooting

unknown package interger-gmp

ghc is compiled with INTEGER_LIBRARY = integer-simple. This might cause trouble if cabal already cached some packages built with integer-gmp. In this case it might help to remove $HOME/.cabal/store and $HOME/.cabal/packages.

nix: `warning: setlocale:

If you get the following error, when envoking nix command, e.g. nix-shell

bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

add the following to $HOME/local/profile

export LOCALE_ARCHIVE=/usr/lib/locale/locale-archive

You may have to adopt /usr/lib/locale.

When on a non glibc Linux, e.g. alpine try to install

nix-env -i glibc-locales

and add the following to $HOME/local/profile

export LOCALE_ARCHIVE="$(nix-env --installed --no-name --out-path --query glibc-locales)/lib/locale/locale-archive"

Compare with NixOS/nix#599.

Dockerfiles

The Dockerfiles are not actually meant to build production images. There shall only verify that my setup works in my supported environment.
