如何在Linux/Unix中创建大小超过2GB的文件? [英] How to create a file of size more than 2GB in Linux/Unix?

问题描述

我有这份家庭作业，我必须使用bittorrent类算法将一个非常大的文件从一个源传输到多台机器.最初，我将文件切成块，然后将块传输到所有目标.目标具有与其他目标共享它们拥有的块的智能.它工作正常.我想传输4GB的文件，所以我将4个1GB的文件解压缩.当我创建4GB的tar文件时，它并没有出错，但是在另一端，当将所有块组装回原始文件时，它出错了，提示超出了文件大小限制.我该如何解决这个2GB的限制问题?

I have this home work where I have to transfer a very big file from one source to multiple machines using bittorrent kinda of algorithm. Initially I am cutting the files in to chunks and I transfer chunks to all the targets. Targets have the intelligence to share the chunks they have with other targets. It works fine. I wanted to transfer a 4GB file so I tarred four 1GB files. It didn't error out when I created the 4GB tar file but at the other end while assembling all the chunks back to the original file it errors out saying file size limit exceeded. How can I go about solving this 2GB limitation problem?

推荐答案

我可以想到两个可能的原因:

I can think of two possible reasons:

• 您没有在Linux内核中启用大文件支持 li>
• 您的应用程序未使用大文件支持进行编译(您可能需要传递gcc额外的标志，以告知它使用某些文件I/O功能的64位版本，例如gcc -D_FILE_OFFSET_BITS=64)

• You don't have Large File Support enabled in your Linux kernel
• Your application isn't compiled with large file support (you might need to pass gcc extra flags to tell it to use 64-bit versions of certain file I/O functions. e.g. gcc -D_FILE_OFFSET_BITS=64)
