Transitive link dependencies are lost for C modules

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

  • Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

When building SourceKit-LSP tests with a change to share the build of LMDB across IndexStoreDB and DocC, we find that SourceKit-LSP tests which depend on IndexStoreDB do not pull in MDB.

swift-lmdb/CLMDB <- IndexStoreDB_Database <- IndexStoreDB_Index <- IndexStoreDB_CIndexStoreDB <- indexstore-db/IndexStoreDB <- SourceKitLSPTests

However, when building SourceKitLSPTests we find that CLMDB is not linked in resulting in undefined references to symbols.

Expected behavior

The transitive closure of dependencies is tracked for the linkage.

Actual behavior

It does appear that CLMDB.lib is, in fact, missing.

compnerd commented

One thing that stands out about the missing dependency - it is the only target declared as a dependency with .product(name: "CLMDB", package: "swift-lmdb").

Never mind, this is a self-inflicted wound from swiftlang/sourcekit-lsp#1768
