Mic*_*yan 8 iphone gcc autotools cross-compiling iphone-sdk-3.0
这是关于iPhone交叉编译的上一个问题的后续内容:
为官方iPhone SDK交叉编译基于Autotools的库
基本上,我正在尝试为iPhone编译Apache Portable Runtime(APR)版本1.3.8(最新版).我目前在配置步骤中遇到以下错误:
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.
我通过"iphone3.1-configure --disable-dso --enable-threads"调用"configure"脚本,其中"iphone3.1-configure"是我编写的以下脚本,用于调用"配置"脚本:

配置错误给我的不是第一次收到"交叉编译时无法运行测试程序"的消息.实际上,"iphone3.1-configure"脚本中的"ac_cv_file__dev_zero = no"和"ac_cv_func_setpgrp_void = yes"元素会导致两个类似的失败测试被绕过.我遇到的问题是我不知道如何绕过这个检查 - 也就是说,我不知道设置什么变量来绕过这个测试以及尝试运行为目标构建的可执行文件的任何其他测试平台.我能够绕过之前的两个类似的测试只是因为我能够找到谷歌上的变通方法...有谁知道要设置什么变量或绕过这个检查的其他方式？
如果有人知道一种方法来抑制交叉编译时无法执行的所有测试,或者你只知道如何抑制这种特定的检查,我将非常感激.非常感谢你.
需要设置以下变量:
使用以下更新的"iphone3.1-configure"脚本配置程序:
