Re: Installing GHC on my MacBook Air

[Steven Smith]

I recommend using macOS package managers to take care of all this. There’s a whole community of knowledgeable folks who have figured out all these build and install details, and I know that it’s simply a matter of doing this to get a working version of the latest, on either x86_64 or arm64 machines:sudo port install ghcThat’s using MacPorts. There are other options, but I strongly recommend MacPorts for several reasons, especially for development tools.On Mar 15, 2023, at 12:04, George Colpitts  wrote:Hi BillI'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_447206I believe the way to fix this is to do the following:rm -fr /usr/local/bin/ghc*rm -fr /usr/local/lib/ghc*./configuresudo xattr -rc .sudo make installHowever I am unsure why you are encountering this as the issue is supposed to have been fixed.CheersGeorgeOn Wed, Mar 15, 2023 at 11:21 AM William McEnaney  wrote:Hi, George,I got this message when I ran make install with the sudo command.

No, Macports ghc links against the symbol iconv from /usr/lib/libSystem. See: 
https://github.com/macports/macports-ports/blob/c7c7f3f90e1140a0d4826bb94502fd7a4ae40459/lang/ghc/Portfile#L213-L218

<https://gitlab.haskell.org/ghc/ghc/-/issues/18752>
https://trac.macports.org/ticket/57821 <https://trac.macports.org/ticket/57821>

The MacPorts ghc binary is rock solid to the best of my knowledge.

If you want to compile ghc against libiconv (not libSystem), then must contend 
with the name mangling issue inherent in the libiconv library, discussed in the 
last link above.

Recommendation on macOS: just install the MacPorts binaries. They work, they’re 
compiled from source, and they’re managed.

Re: osx conundrum

[Steven Smith]

FWIW, MacPorts does compile from source. If you want, just do

sudo port -s install ghc

and watch a multistage compiler build.

That’s where the MacPorts binary installs come from, so it’s just easier to use 
those.

Re: osx conundrum

[Steven Smith]

I’m a maintainer of the MacPorts ghc port. The MacPorts installations do not 
have this issue, whether installed from the buildbot binaries or compiled from 
source, that all work on multiple macOS versions 10.9–11.  Here’s the build 
recipe: 
https://github.com/macports/macports-ports/blob/master/lang/ghc/Portfile 


The iconv symbol issue is known, 
https://gitlab.haskell.org/ghc/ghc/-/issues/18752 
, and packages like MacPorts 
must build around it.

This looks like something specific to your configuration.

If you believe that there is an issue outside your system, please initiate a 
trac ticket at https://trac.macports.org .

GHC Full Bootstrap from Source on macOS

[Steven Smith]

Is there a guide or script to build ghc from source (not the prebuilt binary)?

At MacPorts we’re running into issues on macOS Catalina 10.15 with the 
bootstrapped-from-prebuilt ghc. See https://trac.macports.org/ticket/59467 .

It would preferable and probably more robust to be able to bootstrap everything 
from source, and highly preferable to be able to do this with a clang compiler 
of choice.

GHC 8.8.2 Bootstrap Build Fails on macOS Catalina 10.15, undeclared identifier 'TAG_MASK'

[Steven Smith]

I’m trying to upgrade the MacPorts ghc install to the latest 8.8.2.

The build fails with:
> error: use of undeclared identifier 'TAG_MASK'
> :info:build return (StgWord)p & TAG_MASK;


This is an error observed with previous ghc versions and on other systems, so I 
do not believe it is macOS-specific.  Also, the MacPorts build process simply 
follows the ghc Build & Install instructions: 
https://github.com/ghc/ghc/blob/master/README.md#building--installing

Is there a simple fix by adding an extra flag somewhere?

downloads.haskell.org server is misconfigured, ignores Accept-Encoding, prevents update checks

[Steven Smith]

The downloads.haskell.org server is misconfigured. It's always gzipping its 
response content, ignoring the Accept-Encoding headers. Even if you set 
Accept-Encoding: identity the server sends a compressed response. 

This prevents automated version update checking.
