scala 使用 GMPUtil 处理pidigits

问题描述

Rex Kerr 发布了有关在 Scala 中使用 GMP 的信息，特别是运行 pidigits 程序.libjpargmp.so 是使用 GmpUtil.c 生成的

Rex Kerr has posted info about using GMP with scala, in particular to run the pidigits program. libjpargmp.so is generated using GmpUtil.c

我的问题是:在哪里可以找到 GMPUtil.c?我的谷歌搜索没有任何结果.

My question is: where do I find GMPUtil.c? My google searches haven't turned up anything.

问候，道格

推荐答案

在 Alioth 计算机语言基准游戏论坛上发帖比在此处发帖更有可能产生答案.但是，在这种情况下，您已经很幸运了(尽管我不知道这是否是 StackOverflow 的正确用法).

Posting on the Alioth computer languages benchmark game forum would more likely yield an answer than posting here. However, in this case you've gotten lucky (though I don't know if this is exactly an appropriate use of StackOverflow).
