This function is fundamentally broken.
Not even the ncurses example will compile.
The interface needs to be rethought for it to work (i.e. don't
unconditionally include all pc files, set include path and ld path and
rpath).
Since it is unlikely that in the current this has any user, just drop it for now.
Fixes https://github.com/dhall-lang/dhall-haskell/issues/2267
`pkgs.dhallToNix` currently fails when a Dhall package is
interpolated into the input source code, like this:
```nix
let
pkgs = import <nixpkgs> { };
f = { buildDhallPackage }: buildDhallPackage {
name = "not";
code = "λ(x : Bool) → x == False";
source = true;
};
not = pkgs.dhallPackages.callPackage f {};
in
pkgs.dhallToNix "${not}/source.dhall True"
```
This is because `dhallToNix` was using `builtins.toFile`, which
does not permit inputs with interpolated derivations. However,
`pkgs.writeText` does not have this limitation, so we can switch
to using that instead.
Apparently, a non-existent nsswitch.conf causes a very misleading host
resolution, differing from the defaults people are used to.
According to
https://github.com/golang/go/issues/22846#issuecomment-346377144, glibc
says the default is "dns [!UNAVAIL=return] files".
This means, `/etc/hosts` isn't really honored, causing all sorts of
unexpected behaviour.
Let's prevent this, and first ask `/etc/hosts` before querying DNS, like
we do on NixOS too.
The reason for this change is explained in the long comment I added.
Here's a simple example of the problem:
let
pkgs = import <nixpkgs> { crossSystem.system = "aarch64-linux"; };
in
pkgs.callPackage ({ stdenv, s6-rc }: stdenv.mkDerivation {
name = "s6-rc-compiled";
nativeBuildInputs = [ s6-rc ];
buildCommand = ''
mkdir in
s6-rc-compile $out in
'';
}) {}
We're cross compiling for aarch64 here, so we'd expect the scripts
generated by this derivation to be things we could run on aarch64.
But when I build this on my x86_64 machine, without this change
applied, $out/servicedirs/s6rc-oneshot-runner/run gets generated full
of references to x86_64 non-cross store paths for execline, s6, and
s6-rc.
With this change applied, the scripts generated by the above
expression now refer to the cross-compiled aarch64 store paths for
execline, s6, and s6-rc.
- Reuse build phase from the `buildDunePackage` function.
- Only install the package that was just built (useful for monorepo support).
- Introduces `opam-name` to override the default package name to build with Dune.
GitHub user flexibeast has been porting the html documentation from
skarnet.org to mdoc, making them available as man pages. While the
documentation is non authorative, it is certainly useful and is also
linked from skarnet.org.
buildManPages implements the common mkDerivation machinery common to all
ported man page packages / repositories.
`installCheckPhase` is mainly intended for checks that are part of the
upstream package, for our 'own' checks we prefer `passthru.tests`.
This loses running `buf --help`, but I'm not sure how much that adds
on top of `buf --version`?
skopeo 1.4.x doesn't accept --src-tls-verify as a flag to the *program*,
only as a flag to copy; we must pass it after the "copy" verb, or it
will fail with:
> FATA[0000] unknown flag: --src-tls-verify

Restore the packages to a directory with `--packages`, then run
`./nuget-to-nix.sh [path to packages] > deps.nix`.
In newer versions of mingw, programs compiled with FORTIFY_SOURCE need
to link to libssp or they will have link-time errors.
gmp has been broken since @pstn updated mingw-64 in c60a0b0447
fetchzip downloads the file from specified URL, renames it to basename
of that url, and then relies on unzip to do the unpacking.
The first consequence is that this requires URL to end with proper
extension—otherwise it will fail to unpack. This is not always the
case and input-fonts workarounds this by adding “&.zip” query
parameter (which is obviously a hack and is not guaranteed to work
with every URL).
The second consequence is that basename of the url must be a valid
filename. I’ve tried to build a custom configuration of input-fonts
and I get an error from mv that the filename is too long:

We could use “name” parameter as the filename (that’s how it is used
in fetchurl). However, the previous attempt to do
so (fc01353703) was
reverted (24b5eb61eb) because of the
introduced regression—many fetchzip invocations use names without
extension (also the default name is just “source”).
This commit adds an optional “extension” parameter. If it is set,
fetchzip renames the downloaded file to “download.${extension}”
effectively solving both problems above without introducing a massive
regression.
This is a no-op for all existing packages.
Tested by updating my NixOS setup + the extra inputs-fonts
configuration mentioned above + tons of unstable emacs packages after
a nix-collect-garbage (3Gb downloaded) with this patch applied.
