很抱歉提出了一些问题，但是使用堆栈链接可执行文件在一个实例中无法解释，但在另一个实例中却没有。
这是我的项目：
$ cat stack.yaml
extra-package-dbs: []
packages:
- umecore-hs
- fontrans-tools
extra-deps:
- parsec3-1.0.1.8
- parsec3-numbers-0.1.0
resolver: lts-5.15
flags:
parsec3-numbers:
parsec3: true
这里有两个可执行文件，每个包中有一个。
第一个包umecore-hs的cabal文件的可执行部分如下所示：
Executable umequery
Main-Is: umequery.hs
Hs-Source-Dirs: src
default-language: Haskell2010
build-depends: base, parsec3, filepath, time, bytestring, unix, cryptohash, optparse-applicative, text, base16-bytestring, utf8-string, transformers, regex-pcre, regex-base, direct-sqlite, text , parsec3-numbers
这在我的OS X 10.11.5机器上构建得很好：

数据和时间是我运行构建命令的时间。
好的，第二个包中的相应部分是：
Executable textgrid_import
Main-Is: textgrid_import.hs
Hs-Source-Dirs: src
default-language: Haskell2010
build-depends: base, filepath, directory, optparse-applicative, umecore-hs
但是，当链接二进制文件时，这会失败。 （我包括详细输出，因为这是不使用-v标志时的建议）：

为什么同一台机器上的同一个链接器在第二种情况下无法链接？ 我能想到的一件事是第二个包从第一个包加载库，但我认为这应该是可能的吗？
答案 0 :(得分：0)
首先修复这些警告：警告：umecore-hs.cabal中未列出库组件的模块警告：未列在umecore-hs.cabal中的模块用于＆＃39; umequery＆＃39;组件 - thomie Jun 25 11:35
我认为@tomie解决了它。不知道为什么，但通过明确地包含工作包规范的副本也用于构建第二个可执行文件，然后它开始工作。不知道为什么链接器抱怨而不是编译器，但你去了。它有效。
