説明

I have a Haskell installation with only shared libraries, and cabal's config contains:

library-vanilla: False
library-profiling: False
shared: True
executable-dynamic: True

This fails for packages with build-type: Custom, because cabal-install tries to link setup against non-existent static libraries.

技術スタック: なし
領域: build systemtooling
Issue 種別: bug
難度: 3
推定時間: 1-2 days
活動状況: stale
明確さ: clear
前提条件: Basic knowledge of cabalUnderstanding of static vs shared libraries in Haskell
初心者向け度: 25
調査方針: The issue describes a bug where `executable dynamic: True` is not applied to packages with `build type: Custom`, causing linking failures against absent static libraries. Investigate how cabal install selects linking flags for the setup executable, likely in `Distribution.Simple.Build`. Look for any existing comments or proposed solutions in the discussion. The fix may involve modifying the build system to propagate the dynamic linking setting to the setup executable.
