编译C lib for iPhone [英] Compile C lib for iPhone

问题描述

我正在尝试编译ZeroMQ C绑定，以便能够在iPhone上使用它，这里是我的配置选项：

I'm trying to compile ZeroMQ C binding in order to be able to use it on iPhone, here is my configure options:


./configure --host = arm-apple-darwin --enable-static = yes --enable-shared = no CC = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / arm-apple -darwin10-gcc-4.2.1 CFLAGS = - pipe -std = c99 -Wno-trigraphs -fpascal-strings -O0 -Wreturn-type -Wunused-variable -fmessage-length = 0 -fvisibility = hidden -miphoneos-version- min = 3.1.2 -gdwarf-2 -mthumb -I / Library / iPhone / include -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk -mdynamic-no-picCPP = / Developer /Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / ar AS = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / as LIBTOOL = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / libtool STRIP = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / strip RANLIB = / Developer / Platforms / iPhoneOS.platform / Developer / usr / bin / ranlib


它实际上配置和编译很好，但是当我将它添加到Xcode Frameworks部分时， ： ld：warning：在/path/to/app/libzmq.a中，文件是为不支持的文件格式构建的，这不是被链接的架构（armv7）

It actually configures and compiles fine, but when I add it to Xcode Frameworks section, I get warning: ld: warning: in /path/to/app/libzmq.a, file was built for unsupported file format which is not the architecture being linked (armv7) and a lot of symbol not found errors.

如果我将当前活动结构从armv6更改为armv7，警告消息将更改为armv6。
我做错了什么？

If I change current active architecture from armv6 to armv7, warning message will change it to armv6. What am I doing wrong ?

感谢，
Dan

Thanks, Dan

推荐答案

听起来你正在为iPhone构建一个通用armv6 / armv7二进制文件（这是默认的，所以这是有道理的）。这意味着你需要构建一个通用库来链接。建立两个库，然后使用 lipo 来组合这两个库。

It sounds like you're building a universal armv6/armv7 binary for the iPhone (this is the default, so that makes sense). That means that you need to build a universal library to link against. Build both libraries, and then use lipo to combine the two.

，构建armv6并将其放置在 armv6 / libfoo.a ，并将armv7放在 armv7 / libfoo.a 。然后执行

For example, build the armv6 one and place it at armv6/libfoo.a, and the armv7 one at armv7/libfoo.a. Then run

lipo -arch armv6 armv6/libfoo.a -arch armv7 armv7/libfoo.a -output libfoo.a -create

创建通用库 libfoo.a 。
