我如何用runhaskell增加堆栈大小？ [英] How can I increase the stack size with runhaskell?

问题描述

我正在编写一些一次性的Haskell脚本来解决一些 Project Euler 问题。我不想编译它们是因为我经常需要做的更改的次数很多，但是在一些情况下，我发现我已经用完了堆栈空间。

$ b $ < runhaskell 的文档表示以下语法应该增加堆栈空间：

  runhaskell + RTS -K5M -RTS Script.hs 
  

这永远不会有效（在我试过的任何排列中）。堆栈大小始终为8,388,608。这令人生气，我在Google上找不到太多帮助。

有什么建议吗？我在做什么错了？

解决方案

我猜你正在使用GHC。新发布的6.10.1用户手册第四章说：

lockquote

目前唯一的runghc标志是-f
/ path / to / ghc，它告诉runghc使用
GHC来运行程序。

我没有看到在 http://hackage.haskell.org/trac/ghc 上记录的错误。对我来说似乎很蹩脚。我建议询问irc #ghc或者cvs-ghc邮件列表。

在其他Haskell编译器/解释器中，只有nhc98似乎允许您设置最大值堆栈大小。根据您的操作系统，nhc98可能是一个选项。

I'm writing some disposable Haskell scripts to solve some of the Project Euler problems. I don't really want to have to compile them because of the number of changes I'm constantly having to make, but in a few cases I've found that I've run out of stack space.

The documentation for runhaskell says that the following syntax should increase the stack space:

runhaskell +RTS -K5M -RTS Script.hs

This never, ever works (in any permutation I've tried). The stack size always remains 8,388,608. This is maddening, and I haven't found much help on Google.

Any suggestions? What am I doing wrong?

解决方案

I'm guessing you're using GHC. Chapter 4 of the User's Guide of the newly released 6.10.1 says:

The only runghc flag currently is -f /path/to/ghc, which tells runghc which GHC to use to run the program.

I don't see a bug logged at http://hackage.haskell.org/trac/ghc . Seems pretty lame to me. I'd suggest asking on irc #ghc, or the cvs-ghc mailing list.

Of the other Haskell compilers/interpreters, only nhc98 seems allow you to set the max stack size. Depending on your OS, nhc98 could be an option.
