iphone - 为官方 iPhone SDK 交叉编译基于 Autotools 的库

Question

背景

我正在编写一个针对多种不同手机(包括 iPhone)的程序。该程序依赖于几个第三方库。我在为 iPhone 和 iPhone 模拟器交叉编译这些第三方库时遇到困难。这些库包括 Apache Portable Runtime 和 GNUTLS 及其依赖项。我希望构建的库以前缀“/opt/iphone-3.1”、“/opt/iphone-3.0”、“/opt/iphone-2.2.1”、“/opt/iphone-simulator-3.1”结束”和“/opt/iphone-simulator-3.0”。

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-配置”、“iphonesim3.1-配置”和“iphonesim3.0-配置”)。这就是我遇到麻烦的地方。

我使用的是 Mac OS X 10.6 Snow Leopard 计算机以及官方 Xcode 3.2 + iPhone SDK 3.1。

状态

我目前有以下“iphone3.1-configure”脚本:

#! /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.

在“apr-1.3.8”文件夹中，我正在运行“iphone3.1-configure --disable-dso”，并且得到:

问题

如何修复“iphone3.1-configure”脚本？谢谢。

Answer 1

好的。这仍然没有建立，但它已经走得更远了......

1. C 预处理器无法采用架构。
2. C 预处理器不接受 --sysroot 或 -isystem(仅使用“-I”)。
3. 使用“cpp”而不是“cpp-4.2”(4.2版本有缺陷，而且由于它是预处理器，所以不管你使用哪个版本都没关系，所以你最好使用有效的版本.)

此外，我使用“--enable-threads --disable-dso”调用，而不仅仅是“--disable-dso”。这仍然不起作用......它失败了:

checking for PTHREAD_PROCESS_SHARED in pthread.h... yeschecking for pthread_mutexattr_setpshared... yeschecking for working PROCESS_SHARED locks... configure: error: in `/Users/michaelsafyan/Downloads/apr-1.3.8':configure: error: cannot run test program while cross compilingSee `config.log' for more details.

但是，这可能是 APR 的具体测试存在问题。我正在发布followup question在链接中。
