根據this post最後有一個支持模板haskell和ghci的GHC版本的debian軟件包。爲什麼我不能在Raspberry Pi上安裝GHC 7.8.4的軟件包？
這是真的，我從Raspbian的全新副本開始，我改變了我的/etc/apt/sources.list文件：
deb http://http.debian.net/debian sid main contrib non-free
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspbian.org/raspbian/ wheezy main contrib non-free rpi
我做sudo apt-get update && sudo apt-get upgrade，然後我做了sudo apt-get install ghc和sudo apt-get install cabal-install。
ghc --version報告7.8.4。 GHCi工作得很好，TH也是如此。
但由於某種原因，我無法安裝cabal的任何軟件包。無論我選擇哪一個，我得到一些版本的錯誤：

有誰知道我出軌？

運行'cabal install base-io-access'，看看是否有效。我對此負責（很小，未完成，不要在真實代碼中使用），但它僅依賴於'base'，並且不會執行任何FFI或類似操作。它就像你可以要求的一樣簡單。如果它沒有編譯，那麼它會告訴你，如果它編譯了，那麼它就是軟件包，然後它依賴於軟件包。 – bheklilr
Thanks @bheklilr，這是一個測試，我用我自己的類似包'exact-pi'運行，只依賴於基礎。我剛剛嘗試過你，得到了同樣的結果。 （基本上，不同的臨時文件名，但甚至相同的行號和字符位置。） –
在這種情況下，我不知道。我最初的猜測是試圖鏈接到一些C代碼或其他東西。也許你需要一些額外的標誌GHC讓它編譯正確嗎？我從來沒有嘗試在我的RPi上安裝GHC，所以我在這裏沒有經驗 – bheklilr
