已解决：error: redefinition of ap_hack_apr_allocator_create

Apache Web Server源代码编译总是很有趣。

很少会在全新服务器上首次运行Apache时对其进行编译。

事实是, 这需要很多先决条件, 如果其中任何一个缺少或版本兼容性, 那么你可能必须花费大量时间来修复这些问题。

我正在使用全新的服务器Linux 6.4来安装Apache 2.4.6, 遇到以下错误。

如果你遇到类似的错误, 可以按照以下步骤进行修复。

解

在研究了各种参数之后, 我注意到当你的apr-util版本低于1.4.1时会发生这种情况

• 验证你的apr-util版本。如果找到较低版本, 则必须安装1.4.1或更高版本
• 从http://mirror.nus.edu.sg/apache/apr/下载apr-util源代码
• 解压缩下载的文件

如下编译安装

./configure 
make 
make install

默认情况下, 它将安装在/ usr / local / apr / bin / apu-1-config下

现在, 你可以使用新安装的apr-util来压缩apache, 这应该没问题。

./configure --with-apr-util=/usr/local/apr/bin/apu-1-config
