Hi Bill I'm cc'ing GHC dev and GHC users as someone else may have a better answer, catch a mistake I made etc. Please don't delete them. I believe you have encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206 I believe the way to fix this is to do the following: rm -fr /usr/local/bin/ghc* rm -fr /usr/local/lib/ghc* ./configure sudo xattr -rc . sudo make install However I am unsure why you are encountering this as the issue is supposed to have been fixed.

Somehow I missed that it is now working for you. Great! Definitely no need to report a bug. Haskell is a great language. Enjoy!

Hi Bill, It's easy to forget to do replay all in gmail but it's important to do so in these emails. In your original email you wrote: After installing the compiler, my laptop said its processor was wrong for the binary distribution I chose. If there is a dmg file for *MacOS 12.5.1,* please please link your reply to it. Can you confirm that you no longer have the problem "of processor was wrong for the binary distribution I chose." ? My understanding is that after that you got the error: libHSterminfo-0.4.1.5-ghc9.4.4.dylib” can’t be opened because Apple cannot check it for malicious software. I then suggested you had encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206 and I suggested you do: rm -fr /usr/local/bin/ghc* rm -fr /usr/local/lib/ghc* ./configure sudo xattr -rc . sudo make install You said you did and got a warning "that some program wanted to access my photos when I don't have any." Can you repeat those steps and cut and paste your terminal session into an email? Unfortunately I am too busy to continue replying but with the above I think somebody will be able to help you.

Hi William I think it's best if you submit a bug as described here <https://gitlab.haskell.org/ghc/ghc/-/wikis/report-a-bug> Whether in email or in the bug report it is critical that you describe how the reader can reproduce the bug, i.e. starting from the beginning, describe what you did and what error message(s) you got.

Bill For your latest problem libHSterminfo-0.4.1.5-ghc9.4.4.dylib” can’t be opened because Apple cannot check it for malicious software.

Understanding how warnings on unused functions work
by Raghu Ranganathan 14 Mar '23

14 Mar '23

This is related to a feature in the futhark compiler <https://github.com/diku-dk/futhark/issues/550>, which is a language with a similar module system. I am trying to create a tool to detect unused top-level functions in Futhark, and I have been looking in the ghc codebase to find out how it does so. So far I have found these areas: 1. warning flag <https://gitlab.haskell.org/ghc/ghc/-/blob/master/compiler/GHC/Driver/Flags.…> 2. WarnUnusedTopBinds <https://gitlab.haskell.org/ghc/ghc/-/blob/master/compiler/GHC/Rename/Utils.…> The project is a bit too big for my machine to take, so HLS is not helping me with finding where the computation of unused bindings (specifically functions) is done. I would like some help with finding where ghc does this computation, and maybe some help with the naming conventions of the code. Thanks in advance.

data families/newtype instances allow `DatatypeContext`s ?
by Anthony Clayden 13 Mar '23

13 Mar '23

https://discourse.haskell.org/t/choosing-data-representation-based-on-type/… A `DatatypeContext` on a `newtype instance` gets the usual warning it's deprecated. But the decl is accepted -- at GHC 8.10. (It doesn't achieve what the O.P. was asking for -- but then I wouldn't expect it to.) Is this behaviour deliberate, or more of an accident? I'm surprised such a modern feature (datatype families) tolerates such an old/deprecated feature. I suppose this means the two features are orthogonal -- which is kinda a Good Thing (wrt some continuing discussions). AntC

[ANNOUNCE] GHC 9.6.1-rc1 is now available
by Ben Gamari 03 Mar '23

03 Mar '23

The GHC team is very pleased to announce the availability of the first (and likely final) release candidate of GHC 9.6.1. As usual, binaries and source distributions are available at [downloads.haskell.org](https://downloads.haskell.org/ghc/9.6.1-rc1/). Beginning with GHC 9.6.1, GHC can be built as a cross-compiler to WebAssembly and JavaScript. This is an important step towards robust support for compiling Haskell to the Web, but there are a few caveats to be aware of in the 9.6 series: - Both the Javascript and WebAssembly backends are still at an early stage of development and are present in this release as a technology preview - Using GHC as a cross-compiler is not as easy as we would like it to be; in particular, there are challenges related to Template Haskell - GHC is not yet run-time retargetable; a given GHC binary targets exactly one platform, and both WebAssembly and JavaScript are considered platforms for this purpose. Cross-compilers must be built from source by their users We hope to lift all of these limitations in future releases. Additionally, 9.6.1 will include: - Significant latency improvements in the non-moving garbage collector - Efficient runtime support for delimited continuations - Improvements in compiler error messages - Numerous improvements in the compiler's memory usage See the [release notes][] for a comprehensive accounting of changes in this release. As always, one can find a migration guide to aid in transitioning from older releases on the [GHC Wiki][migration-guide]. We have also recently started extending our release process to cover a wider set of Linux distributions. In particular, we now offer Rocky 8 and Ubuntu 20.04 binary distributions which cover RedHat-derivative and distributions using older `glibc` releases (namely 2.27), respectively. Please do give this release a try and open a [ticket][] if you see anything amiss. If all goes well we expect the final release should be available by late next week. Happy Haskelling, ~ Ben [ticket]: https://gitlab.haskell.org/ghc/ghc/issues/ [migration-guide]: https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.6 [release notes]: https://downloads.haskell.org/ghc/9.6.1-rc1/docs/users_guide/9.6.1-notes.ht…

[Haskell] [ANNOUNCE] GHC 9.2.7 released
by Zubin Duggal 27 Feb '23

27 Feb '23

The GHC developers are happy to announce the availability of GHC 9.2.7. Binary distributions, source distributions, and documentation are available at [downloads.haskell.org](https://downloads.haskell.org/ghc/9.2.7). Download Page: https://www.haskell.org/ghc/download_ghc_9_2_7.html Blog Post: https://www.haskell.org/ghc/blog/20230227-ghc-9.2.7-released.html This release is primarily a bugfix release addressing a few issues found in 9.2.6. These include: * A fix for a bug with the RTS linker being unable to resolve the `setKeepCafs` symbol which started being used by the GHC library in 9.2.6, resulting in code depending on this symbol failing to load in GHCi or via a compile time splice when using a statically linked GHC, such as on Windows (#22961). * A fix a bug with the alignment of RTS data structures that could result in segfaults when compiled with high optimisation settings on certain platforms (#22975 , #22965). * A fix for a bug in the simplifier related to placeholder values (rubbish literals) emitted by the worker/wrapper optimisation leading to -dcore-lint errors and compiler panics in certain cases (#19882, #22914, #23000). * Easier installation of binary distribution on MacOS platforms by changing the installation Makefile to remove the quarantine attribute when installing. * ... and a few more. See the [release notes] for a full accounting. As some of the fixed issues do affect correctness users are encouraged to upgrade promptly. We would like to thank Microsoft Azure, GitHub, IOG, the Zw3rk stake pool, Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, Haskell Foundation, and other anonymous contributors whose on-going financial and in-kind support has facilitated GHC maintenance and release management over the years. Finally, this release would not have been possible without the hundreds of open-source contributors whose work comprise this release. As always, do give this release a try and open a [ticket][] if you see anything amiss. Happy compiling, - Zubin [ticket]: https://gitlab.haskell.org/ghc/ghc/-/issues/new [release notes]: https://downloads.haskell.org/~ghc/9.2.7/docs/html/users_guide/9.2.7-notes.…
