我已经在我的 Windows 7 64 位系统上成功安装了 Cygwin。
我已经安装并编译了很多东西，没有任何问题。
--with-imap and --with-imap-ssl使用选项编译 PHP 5.4.9 时出现错误。- 我已经安装
c-client在 Cygwin 中，它似乎安装在/usr/include/c-client. - 然后，我
./configure使用 .php 将 for PHP 指向该位置--with-imap=/usr/include/c-client。
即使这样做了，我在配置过程中也会收到以下错误：
configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information.
我找不到任何关于 Cygwin 的更多信息。Linux 的大多数来源/信息都说这是因为缺少 c-client，但就我而言，我安装了 c-client。
这是因为 Cygwin 不支持 PHP 的 IMAP 扩展吗？有没有人在 Cygwin 上成功编译了 PHP 的 IMAP 扩展？
更新：刚刚从这里下载了 c-client，希望如果我自己编译它，我会得到所需的一切，包括libc-client.a.
该软件包看起来很有希望，因为它包含 Cygwin 的构建目标。但是，如果我运行make cyg，我最终会出现此错误：

在这一点上，我不知道问题出在 openssl 头文件还是 libc-client 上。我的 OpenSSL 版本是OpenSSL 1.0.1c 10 May 2012.
任何输入表示赞赏。
我通过设置 SSLTYPE=none 尝试在不使用 SSL 的情况下进行构建，并且构建成功。但是，我需要 SSL 支持，所以我仍在尝试找到一种使用 SSL 构建的方法。
