问题描述
我正在编写一个针对几种不同手机的程序，包括iPhone。该计划取决于几个第三方库。我很难为iPhone和iPhone模拟器交叉编译这些第三方库。这些库包括Apache Portable Runtime和GNUTLS，以及它们的依赖项。我希望构建的库最后以前缀/opt/iphone-3.1，/ opt / iphone-3.0，/ opt / iphone-2.2.1，/ opt /iphone-simulator-3.1 和/opt/iphone-simulator-3.0分别。
I am writing a program that targets several different phones, including the iPhone. The program depends on several thirdparty libraries. I am having difficulty cross-compiling these thirdparty libraries for the iPhone and iPhone simulator. The libraries include the Apache Portable Runtime and GNUTLS, as well as their dependencies. I would like the built libraries to end up in the prefixes "/opt/iphone-3.1", "/opt/iphone-3.0", "/opt/iphone-2.2.1", "/opt/iphone-simulator-3.1", and "/opt/iphone-simulator-3.0", respectively.
为了使交叉编译过程易于重复，我正在创建脚本来调用每个目标平台的配置脚本（iphone3.1-configure，iphone3.0-configure，iphone2.2.1-configure，iphonesim3.1-configure和iphonesim3.0-configure ）。这是我遇到麻烦的地方。
In order to make the cross-compilation process easily repeatable, I am creating scripts to invoke the "configure" script for each of the target platforms ("iphone3.1-configure", "iphone3.0-configure", "iphone2.2.1-configure", "iphonesim3.1-configure", and "iphonesim3.0-configure"). This is where I am having trouble.
我正在使用Mac OS X 10.6 Snow Leopard计算机和官方Xcode 3.2 + iPhone SDK 3.1。
I am using a Mac OS X 10.6 Snow Leopard computer with the official Xcode 3.2 + iPhone SDK 3.1.
我目前有以下iphone3.1-configure脚本：
I currently have the following "iphone3.1-configure" script:
#! /bin/bash
#
# Program : iphone3.1-configure
# Author : Michael Aaron Safyan
# Synopsis :
# This program runs the "configure" script generated by the
# GNU Autotools in order to cross-compile thirdparty libraries
# for the iPhone 3.1 SDK. Run this script while in a directory
# containing an autotools "configure" script. Once run, this
# you can use "make" and "sudo make install" to build the library.
# An install prefix of "/opt/iphone-3.1/" is used.

问题
如何修复iphone3.1-configure脚本？谢谢。
Question
How do I fix the "iphone3.1-configure" script? Thanks.
推荐答案
好的。这仍然没有建立，但它进一步发展...
Ok. This still doesn't build, but it gets much further...
- C预处理器无法采用架构。
- C预处理器不接受--sysroot或-isystem（只使用'-I'）。
- 使用cpp而不是cpp-4.2（ 4.2版本是有缺陷的，因为它是预处理器，无论如何，使用哪个版本并不重要，所以你不妨使用那个有效的版本。）

此外，我正在调用--enable-threads --disable-dso，而不仅仅是--disable-dso。这仍然无效...它失败了：
Also, I am invoking with "--enable-threads --disable-dso", not just "--disable-dso". This still doesn't work... it is failing with:
checking for PTHREAD_PROCESS_SHARED in pthread.h... yes
checking for pthread_mutexattr_setpshared... yes
checking for working PROCESS_SHARED locks... configure: error: in `/Users/michaelsafyan/Downloads/apr-1.3.8':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.
然而，这可能是APR特定测试的问题。我在链接上发布了。
However, this may be a problem with APR's specific tests. I am posting a followup question at the link.
我在交叉编译适用于iPhone的Apache Portable Runtime 。
