我在linux redhat服务器上安装Apache httpd-2.4.9，配置命令成功执行，并且在执行make命令时它显示错误为（错误：＆＃39; apr_OFN_ap_proxy_retry_worker_t＆＃39;未声明（首次使用）这个功能））。请在下面找到并帮我解决这个问题。

编译错误：

error: 'apr_OFN_ap_proxy_retry_worker_t' undeclared (first use in this function)

在编译'mod_lbmethod_byrequests.c'时，更具体地说，在编译函数'find_best_byrequests（）'时（在'mod_lbmethod_byrequests.c'的第88行）;编译器遇到了一个未正确定义的符号'apr_OFN_ap_proxy_retry_worker_t'。

这种类型的错误通常通过包含.h文件来克服，该文件为编译器定义了未知符号（'apr_OFN_ap_proxy_retry_worker_t'）。

在尝试安装新的httpd以替换旧的现有httpd时，我也遇到了这个问题。在我的例子中，问题似乎与使用$ HOME / local作为libpcre位置有关，它恰好也包含旧的httpd安装（在$ HOME / local / include中包含旧的头文件）。似乎这些安装的旧头文件在编译新的httpd时遇到了问题。从$ HOME / local / include中删除旧的httpd头文件解决了这个问题。

答案 2 :(得分：0)

我今天遇到了这个问题并且被困了一会儿。我看到了这篇SO文章，并开始查看源代码，试图弄清楚为什么apr_OFN_ap_proxy_retry_worker_t未声明。我按照apr和apr-util的说明（即将它们下载到srclib中），所以我不明白为什么apr变量是未声明的。好吧，事实证明它是“未声明的”，因为我没有使用--with-included-apr配置选项。因此，系统正在使用它可以找到的任何相关头文件。而且，由于我在系统上安装了旧的Apache，它在/ usr / include或类似的东西中找到了它。添加--with-included-apr后，我能够重新配置，制作并成功安装Apache 2.4.10。
