配置脚本和ldid

由于Killed: 9错误导致配置脚本的摘录失败，这就是说iOS 5只能运行签名的应用程序。所以我需要找到一种方法把ldid -s一些在这些测试中，只有问题是在哪里。配置脚本和ldid

任何???

失败

此外，它是一个大写'-S' - 小写's' *删除*伪代码。 – 2012-09-16 21:01:31

我不得不承认，我的能力，读什么但最简单的shell脚本很差，但基本上，您需要在运行之前伪造可执行代码。它看起来像你想运行的可执行文件被称为conftest，对吧？所以，尽量在这一块上面签名：

if { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$gmp_compile\""; } >&5 
    (eval $gmp_compile) 2>&5 
    ac_status=$? 
    $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5 
    test $ac_status = 0; }; then 

    #begin added code 
    ldid -S ./conftest 
    #end added code 

    if (./a.out || ./b.out || ./a.exe || ./a_out.exe || ./conftest) >&5 2>&1; then 
    cc_for_build_works=yes 
    fi 
fi

显然，你可能需要提供完整的路径ldid（例如/usr/bin/ldid），如果它不是在现有PATH找到。

更新：按照下面的海报的评论，a.out实际上是需要进行签名，而不是conftest可执行文件。

仍然不好'' –

@JohnBruseliusJensen，你能给我们一些比这更多的信息吗？你在看什么？控制台输出？错误讯息？ “仍然没有好处”不是很有用。 – Nate

对不起，5分钟前，我发现'test $ ac_status = 0; };然后ldid -S ./a.out'正在工作，但现在我再次被卡住了... with configure：error：无法确定可执行文件后缀 –
