Description of issue

While upgrading era, its dependency pandoc fails to upgrade during the execution of "cabal v2-install pandoc-cli". The last 15 lines of the install log are as follows:

[5 of 5] Compiling Data.ByteString.Base64.URL.Lazy ( Data/ByteString/Base64/URL/Lazy.hs, dist/build/Data/ByteString/Base64/URL/Lazy.o, dist/build/Data/ByteString/Base64/URL/Lazy.dyn_o )

The root cause appears to be that the linker flag "-no_warn_duplicate_libraries" is not available on Xcode 14.3.1 - presumably it is only available on Xcode 15.2 or later. Ventura was a supported macOS version until just recently - in fact, technically it should still be considered supported as macOS 26 is not released yet and binary bottles should be available. However, understanding that the Tahoe release is imminent, as a (soon-to-be)Tier 2 system, this issue should be looked at so that build from source is possible.

[p-linnane]

macOS 26 was released today. We stopped building bottles for Ventura last week, and moved Ventura to Tier 3 yesterday.

Like your brew doctor output says, you should upgrade to the latest Command Line Tools version for Ventura, which is 15.2.

OK, that worked - didn't realize I could get above Xcode 14 because it wasn't auto-updating through Software Update, but 15.1 installed and the build seems to be working.

BTW, the message is slightly wrong, as 15.2 isn't available in the Developer downloads. 15.1 is (and 15.3 requires Sonoma).

Thanks for the hint. Feel free to close this issue.
