是否可以通過Cabal編譯最大數量的模塊？

Question

是否可以通過Cabal / via GHC編譯最大數量的模塊？

我確實有一個相當大的項目（很多自動生成的模塊），它不能使用cabal進行編譯，但是沒有出現錯誤信息。 Cabal只是默默地退出， exit code 127 （Mac OS X，發生在10.6和10.8，只測試了這兩個平台; GHC 7.4.2）。

編輯 cabal build -v3輸出：

>>> cabal build -v3
Using internal setup method with build-type Simple and args:
["build","--verbose=3"]
creating dist/build
creating dist/build/autogen
Building java-bindings-1.0...

/usr/bin/ghc returned ExitFailure 127

現在我看到輸出我相信它可能是傳遞給ghc的命令行參數的數量 - 我相信操作系統會施加最大長度...有沒有辦法繞過這個限制？

Answer 1

是 - 操作系統對命令行的長度設置了限制，該命令行在內部用於最終鏈接步驟。

我不知道在這里建議什么，除了報告針對Cabal的錯誤並且可能試圖自己修復它。 如果你走那條路，Cabal的代碼很可讀。 :)
