cabal @3.10.2.0_2 won’t build from source on 10.15: Warning: Failed to build documentation for Cabal-syntax-3.10.2.0

[Gandoon (Erik Hedlund)]

I tried to upgrade pandoc which depends on cabal. I am building from source. As previously, the failing cabal build prevents successful upgrade of pandoc. I ran into proplems earlier, see #68957, which could be solved by a tweak to the portfile. However, that tweak is now incorporated in the distributed portfile. I am unsure what is the issue this time as the problem occurs during the destroot stage. I have tried various standard tweaks to macports.conf, such as turning off ccache, forcing the current architecture, and changing archive format (despite the previous versions were just fine with xz). None of the above worked. A little snippet of the final output of the port -v upgrade pandoc is included below. Note that this happens during the cabal build, and that I am on MacOS 10.15.7.

Log from failed destroot of cabal @3.10.2.0_2 on MacOS 10.15

[essandess (Steve Smith)]

Please see ​https://github.com/macports/macports-ports/pull/23008. Just throwing in the towel and rolling back to macOS 10.16 == Darwin version 20 to build from source.

@jmroot, the buildbots for cabal work on 10.15, so it's not clear if this isn't an isolated issue to @Gandoon. Why isn't MacPorts installing the pre-built binary for either pandoc or cabal? This doesn't appear to be an issue associated with either port.

See:

• ​https://ports.macports.org/port/cabal/builds/
• ​https://ports.macports.org/port/pandoc/builds/
