阴谋集团没有在库中构建所有模块

问：

我有这个库gsdl.cabal文件：

cabal-version:  3.6
name:           gsdl
version:        0.0
synopsis:       Global Script source manipulation libraries
homepage:       https://globalscript.org/
author:         Jonathan Cast
copyright:      © Jonathan Cast
maintainer:     Jonathan Cast <[email protected]>
license-file:   PSL
build-type:     Simple
stability:      alpha
extra-source-files: README, COPYRIGHT

library
    build-depends: base
    exposed-modules: GSDL.Core.AST, GSDL.Core.ReadFile
    hs-source-dirs: hslib

以及此可执行的 gsac.cabal 文件：

cabal-version:  3.6
name:           hsgsac
version:        0.0
synopsis:       A compilation pass for converting Global Script Core code to String Code
author:         Jonathan Cast
copyright:      © Jonathan Cast
maintainer:     Jonathan Cast <[email protected]>
license-file:   PSL
build-type:     Simple
stability:      alpha

executable gsac
    main-is: gsac.hs
    build-depends: base, gsdl

我在库源目录中运行，输出如下：cabal sdist -o /home/jcast/globalscript/haskell-packages

Wrote tarball sdist to
/home/jcast/globalscript/haskell-packages/gsdl-0.0.tar.gz

然后我在可执行源目录中运行，输出如下：cabal build --config-file=/home/jcast/globalscript/etc/cabal

什么？它只是编译库中的一个模块。为什么？

/home/jcast/globalscript/etc/cabal是：

repository hackage.haskell.org
    url: http://hackage.haskell.org/

repository globalscript
    url: file+noindex:///home/jcast/globalscript/haskell-packages

ReadFile.hs是

module GSDL.Core.ReadFile (readCoreFile) where

readCoreFile = error "readCoreFile next"

doSomethingElse = error "doSomethingElse next"

AST.hs是

module GSDL.Core.AST (readCoreFile) where

readCoreFile = error "readCoreFile next"

doSomething = error "doSomething next"
