new package: ghcup-0.1.17.4
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.
-->

`[ci skip]` (on local machine, the build takes about 2-3 hours)
 
#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.

Comment:
As of recently, the build has starting breaking for me, presumably because Void has updated its GHC to 9.0.2 (9836c283a4706e5d3e84f0024a852d0ee18acd0f), introducing some version-solving errors with ghcup's dependencies (which explicitly depend on a version of `base` older than the one included in GHC 9.0.2).  I'm working on getting it fixed right now...

Comment:
`curl` and `wget` are optional runtime dependencies.

Additionally, you need at least these **runtime dependencies** to install GHC via ghcup: `gcc gmp make ncurses ncurses-libtinfo-libs perl`

Comment:
The internal downloader can cause issues with esoteric proxy configurations. In that case users can do

```sh
ghcup config set downloader Curl
```

to set the downloader back to curl, which can handle it. This should be a post-install message as well.

+ghcup comes with an internal downloader, but optionally depends on curl and/or

+first make sure they are installed, then run `ghcup config set downloader Curl`.

+Also, ghcup requires $GHCUP_INSTALL_BASE_PREFIX/.ghcup/bin to be in your PATH
+(by default, $GHCUP_INSTALL_BASE_PREFIX is $HOME); make sure to update your

Re: [PR PATCH] [Updated] new package: ghcup-0.1.17.4

[kwshi]

[-- Attachment #1: Type: text/plain, Size: 1637 bytes --]

There is an updated pull request by kwshi against master on the void-packages repository

https://github.com/kwshi/void-packages ghcup-0.1.17.4
https://github.com/void-linux/void-packages/pull/35624

new package: ghcup-0.1.17.4
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.
-->
 
#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.

+ghcup comes with an internal downloader, but optionally depends on curl and/or
+wget for more advanced usages (e.g., proxying).  To use curl/wget as downloader,
+first make sure they are installed, then run `ghcup config set downloader Curl`.
+
+Also, ghcup requires $GHCUP_INSTALL_BASE_PREFIX/.ghcup/bin to be in your PATH
+(by default, $GHCUP_INSTALL_BASE_PREFIX is $HOME); make sure to update your
+shell launch scripts accordingly. Alternatively, when GHCUP_USE_XDG_DIRS is set,
+GHCUP uses XDG-ish directories.

There is an updated pull request by kwshi against master on the void-packages repository

https://github.com/kwshi/void-packages ghcup-0.1.17.4
https://github.com/void-linux/void-packages/pull/35624

new package: ghcup-0.1.17.8
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.
-->
 
#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.

+ghcup comes with an internal downloader, but optionally depends on curl and/or

Re: [PR PATCH] [Updated] new package: ghcup-0.1.17.8

[-- Attachment #1: Type: text/plain, Size: 1637 bytes --]

There is an updated pull request by kwshi against master on the void-packages repository

https://github.com/kwshi/void-packages ghcup-0.1.17.4
https://github.com/void-linux/void-packages/pull/35624

new package: ghcup-0.1.17.8
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.
-->
 
#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.

Comment:
I've applied @hasufell's patch and gotten the build to work; compilation on/to non-`x86_64` architectures or musl unfortunately doesn't work currently because some of ghcup's dependencies are incompatible (e.g., haskell's `libarchive` package explicitly imports a glibc header).  This package template is ready for review.

That can't be. The ghcup binaries are built on alpine linux with musl.

There's a static libarchive option: `-f-system-libarchive`

Weird-- I've tried building with `-f-system-libarchive` and the error still appears. The relevant error message, I think, is
```
c/archive_platform.h:84:10: error:
     fatal error: sys/cdefs.h: No such file or directory
       84 | #include <sys/cdefs.h>
          |          ^~~~~~~~~~~~~
   |
84 | #include <sys/cdefs.h>
```
Where all googled instances of `sys/cdefs.h` seem to point to GNU libc.  The full error log on the workflow run is at https://github.com/void-linux/void-packages/runs/6742127441?check_suite_focus=true (`x86_64-musl` architecture run).

I'll do some more investigation to see what's going on.

> > I've applied @hasufell's patch and gotten the build to work; compilation on/to non-`x86_64` architectures or musl unfortunately doesn't work currently because some of ghcup's dependencies are incompatible (e.g., haskell's `libarchive` package explicitly imports a glibc header).  This package template is ready for review.

Weird-- I've tried building with `-f-system-libarchive` and the error still appears. The relevant error message, I think, is
```
c/archive_platform.h:84:10: error:
     fatal error: sys/cdefs.h: No such file or directory
       84 | #include <sys/cdefs.h>
          |          ^~~~~~~~~~~~~
   |
84 | #include <sys/cdefs.h>
```
Where all googled instances of `sys/cdefs.h` seem to point to GNU libc.  The full error log on the workflow run is at https://github.com/void-linux/void-packages.

I've updated the package template to use `-f-system-libarchive`, and as you can see from the [CI logs](https://github.com/void-linux/void-packages/runs/6833102145?check_suite_focus=true) the same error still occurs; cabal is still trying to build the `libarchive` library, even though per my understanding it shouldn't (if we're using static libarchive).

I'll do some more investigation on alpine to see what might explain this disparity.

There's a closed pull request on the void-packages repository

new package: ghcup-0.1.17.8
https://github.com/void-linux/void-packages/pull/35624

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.
-->
 
#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.
