找出链接器错误的内容。也许它很容易修复。也许在StackOverflow上询问它。 ;）任何想法是什么？
尝试找出我的项目使用Happy的哪个依赖项，看看我能不能使用它。我试图通过stack list-dependencies --depth=100和stack dot --external but neither of those helped me unfortunately来解决这个问题
我怎么能找出哪些直接依赖依赖它（可能是间接的）？
尝试说服stack使用我能够通过happy获得的系统级可用pkg install hs-happy二进制文件。我怎么能这样做？
从Linux交叉编译FreeBSD。我是否正确怀疑如果我有交叉编译器，这可能不是问题？无论哪种方式，设置linux-＆gt; FreeBSD交叉编译器都会很困难吗？我怎么能这样做呢？
尝试远离需要FreeBSD。不幸的是，我的托管服务提供商目前只支持FreeBSD，我非常喜欢它们的其他原因（价格和相关理念的价值）。也许，如果所有其他方法都失败了，你能告诉我你的Haskell项目最喜欢的Linux托管服务提供商吗？
我怀疑选项＃1或＃3可能是最无痛的 或者你们中间还有其他想法吗？
答案 0 :(得分：0)
感谢@ user2407038和@Sibi评论中的指针，我设法从1.0.1升级到堆栈1.4.0，并将stack setup升级为隔离的GHC。
happy像魅力一样安装，现在一切都很好。
