libpcap的可以被编译为iPhone / ARMv6的？ [英] Can libpcap be compiled for iPhone/armv6?

问题描述

试图编译它使用pcap.h.基本程序我已经成立了，它使用iPhone SDK 3.1.3为iPhone 3GS在我的Mac OSX框中环境。我还安装了libpcap的到〜/ libpcap的，所以我可以告诉GCC到哪里寻找使用-I标志的标头。然而，它不能用LD警告说，该文件是所需的架构没有。

Trying to compile a basic program which uses pcap.h. I've set up the environment on my Mac OSX box which uses the iPhone 3.1.3 SDK for an iPhone 3GS. I've also installed libpcap to ~/libpcap so I can tell gcc where to look for the headers using the -I flag. However, it fails with an ld warning saying the file is not of the required architecture.

我用下面的行编译：

/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I /Users/abnev/libpcap/include -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk -o pcap pcap.c -lpcap

错误的产生幸福是：

Error's being generated are:

ld: warning: in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/lib/libpcap.dylib, file is not of required architecture

collect2: ld returned 1 exit status

我现在认为我需要重新编译libpcap的为ARMv6体系结构（iPhone），但检查的./configure选项于事无补。我试图谷歌对围绕这一点，但很少有在那里。

I assume now that I need to recompile libpcap for the armv6 architecture (iPhone) but checking the ./configure options doesn't help. I've attempted to Google around for this but there is very little out there.

推荐答案

pcap.c 未在源libpcap的，它的有一个的源文件到libpcap的。你必须编译所有的源文件并将其建设成一个库。

pcap.c isn't the source to libpcap, it's one of the source files to libpcap. You'd have to compile all the source files and build them into a library.

做

CFLAGS="-I /Users/abnev/libpcap/include -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk" ./configure

的可能的生成Makefile，将交叉编译libpcap的适用于iOS。

might produce a Makefile that would cross-compile libpcap for iOS.

我presume要安装libpcap的，或者使用内置的应用吧，在越狱的iPhone，至少如果你要来捕获数据包，因为你需要以root访问权限的libpcap的是能够为了打开一个BPF设备，以便能够捕获

I presume you will be installing libpcap, or the application built using it, on a jailbroken iPhone, at least if you're going to be capturing packets, because you would need root access in order for libpcap to be able to open a BPF device in order to be able to capture.
