ios - 配置脚本和ldid

Question

由于 Killed: 9 错误，配置脚本的摘录失败，这是 iOS 5 只能运行签名 应用程序。所以我需要找到一种方法将 ldid -s 放在这些测试的某个位置，唯一的问题是在哪里。

有人吗？？？

失败了

checking build system compiler gcc... no
checking build system compiler gcc -g -O2 ... no
checking build system compiler cc... no

最后是 ./configure 脚本..

      { $as_echo "$as_me:${as_lineno-$LINENO}: checking build system compiler $CC_FOR_BUILD" >&5
    $as_echo_n "checking build system compiler $CC_FOR_BUILD... " >&6; }
    # remove anything that might look like compiler output to our "||" expression
    rm -f conftest* a.out b.out a.exe a_out.exe
    cat >conftest.c <<EOF
    int
    main ()
    {
      exit(0);
    }
    EOF
    gmp_compile="$CC_FOR_BUILD conftest.c"
    cc_for_build_works=no
    if { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$gmp_compile\""; } >&5

      ac_status=$?

      test $ac_status = 0; }; then

    elif test -n "$HOST_CC"; then

我不得不承认，除了最简单的 shell 脚本之外，我的阅读能力很差，但基本上，您需要在运行可执行文件之前对其进行伪代码签名。看起来您要运行的可执行文件名为 conftest，对吧？所以，尝试在这个 block 中签名:

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，如果在现有的 PATH< 中找不到，您可能需要提供 ldid 的完整路径(例如 /usr/bin/ldid)/.

更新:根据下面发帖人的评论，a.out 实际上是需要签名的可执行文件，而不是conftest。
