Тупо скопипастил текст .nix файла для ksh. Этот вариант начал собираться, но вывалился с ошибкой

nmake --base --compile '--file=/build/source/src/cmd/nmake/Makerules.mk'

nmake это же виндовый мейк.

Ну все. Сломалось :-( Года два назад еще собиралось

Вообще, кроме nix-env есть ещё nix-shell и nix-build. Используй их.

Гугл нашёл вот этот nmake, может, он поможет: https://github.com/att/vizgems/tree/master/src/cmd/nmake

добавь в свой вариант python и which в зависимости, продвинешься дальше

Добраться до полного лога сборки /build/source/build/meson-logs/meson-log.txt не представляется возможным. Или я не знаю, как это сделать.

Мимопробегал

Удивлён, что ksh перешёл не на богомерзкий CMake, а на более-менее нормальный Meson.

Так победим!

Шапку поправь сам. doCheck я убрал, потому что в тестах много FHS, они сфейлятся.

with import <nixpkgs> {}; 

stdenv.mkDerivation rec {

Спасибо! Вот такой код заработал:

{ stdenv, fetchurl, meson, ninja, fetchFromGitHub, gcc-unwrapped, which, python }:

with import <nixpkgs> {}; 

stdenv.mkDerivation rec {
  name = "ksh-${version}";
  version = "93v";

  src = fetchFromGitHub {
    owner  = "att";
    repo   = "ast";
    rev    = "b8d88244ae87857e7bbd6da230ffbbc51165df70";
    sha256 = "12kf14n8vz36hnsy3wp6lnyv1841p7hcq25y1d78w532dil69lx9";

Они же на сандбоксы перешли по дефолту. Можно пробовать это

breakpointHook

This hook will make a build pause instead of stopping when a failure happen. It prevents nix from cleaning up the build environment immediatly and allows the user to attach to a build environment using the cntr command. On build error it will print the instruction that are neccessary for cntr. Installing cntr and running the command will provide shell access to the build sandbox of failed build. At /var/lib/cntr the sandbox filesystem is mounted. All commands and files of the system are still accessible within the shell. To execute commands from the sandbox use the cntr exec subcommand. Note that cntr also needs to be executed on the machine that is doing the build, which might be not the case when remote builders are enabled. cntr is only supported on linux based platforms.

Интересная фича, спасибо.

В апстрим закинуть не забудь.

Не бойся, это не бюрократы как в Debian, и не токсичные самодуры из Gentoo. В NixOS некоторые pull request принимают за час.

Разберусь как работать с GitHub и закину PR.

Тут хорошее описание.

Хорошо написано. Запилил Pull Request. Спасибо за ссылку.
