ghc: fails to run due to missing symlinks

[MichaelJFischer]

The ghc package builds correctly but fails to run because four needed symbolic are missing. The package refers internally to the versions without the "-prebuilt" suffix.

ghci -> ghci-9.6.3
ghci-9.6.3 -> ghci-9.6.3-prebuilt
ghc -> ghc-9.6.3
ghc-9.6.3 -> ghc-9.6.3-prebuilt

but -- it makes no sense to build ghc if it was just going to use the prebuilt ghc anyway....

and -- this port never needed this before, all these years.

So ... something is wrong with this here. Can you give some background to why you feel this is needed?

[MichaelJFischer]

When I migrated from Ventura to Sonoma a few weeks ago, ghc failed to build, so I removed it from myports.txt and continued the migration without ghc.

I needed ghc a couple of days ago, so I did a port install ghc. It ran for a very long time but eventually completed, and there were the "prebuilt" versions of ghc in /opt/local/bin, without all of the needed links. Once I manually installed the links, it worked fine.

Probably I should have done some sort of a cleanup after the build failure?

[kencu (Ken)]

the ghc port has been failing to build for a while now due to an issue building a pdf manual…the prebuilt ghc should install in a couple of minutes at most.

I suspect the prebuilt installed but the real ghc did not, due to the build failure.

what does this show you?

port -v installed | grep ghc

This latest commit apparently fails to address the issue: ​https://github.com/macports/macports-ports/commit/99d3a312a2d08a212782999e0db71afa79e350ad#diff-c7968cfa7dd4491c4f36b05d17922247eee14b20e9a0abd8e2a05879af62c173

I recommend either rolling back to the latest version of ghc that builds and waiting for upstream to address this issue, or commenting out the Portfile commands that build the documentation.

[kencu (Ken)]

the latest commit fixed the ghc 9.6.3 build on almost every system, according to the buildbot

one or two fails to sort out.

port -v installed | grep ghc

so what you might do here is to

1. remove your symlinks
2. sudo port -f uninstall ghc-prebuilt
3. sudo port -v install ghc

and see where that gets you... it should work out.

[kencu (Ken)]

make sure your ports are fully up to date -- ghc was fixed only 2 days ago

sudo port selfupdate

Console output from sudo port -v install ghc

Followed Ken's suggestions. Build succeeded. Symbolic links were created. ghc and ghci both work now!

Thank you, Ken, for your help at resolving this issue.
