如何使用“make”使用64位库，因为ELFCLASS64错误 [英] How to use "make" to use 64 bit libs because of ELFCLASS64 error

问题描述

如何使用configure和make工具指定使用64位元程式库？我认为这是自动的，但我错误的ELF类。

How can I use configure and make tools to specify to use 64 bit libraries? I thought it was automatic, but I get wrong ELF Class.

我试图编译Xdebug Ubuntu 64用于LAMPP（XAMPP for Linux） p>

I'm trying to compile Xdebug for Ubuntu 64 for use with LAMPP (XAMPP for Linux).

./lampp start 

Failed loading /opt/lampp/lib/php/extensions/xdebug.so:  /opt/lampp/lib/php/extensions/xdebug.so: wrong ELF class: ELFCLASS64

./ configure 对我来说看起来OK，并且make的工作没有错误，我复制了配置，如果相关：

The ./configure looks OK to me, and the make works without errors, I've copied the configure in case its relevant:

推荐答案

我不确定错误，编译xdebug？它在Ubuntu的存储库中作为php5-xdebug（ sudo apt-get install php5-xdebug ）。虽然你没有提及你的发行版，也许它的名字相似吗？

I'm not sure of the error, but why are you compiling xdebug? Its available in the repositories of Ubuntu as php5-xdebug (sudo apt-get install php5-xdebug). Though you don't mention your distribution, perhaps its under a similar name?

但是为了回答你的问题，错误信息看起来像xdebug > 64位，但这是一个问题（是lampp执行32位二进制？）

But to answer your question, the error message looks like xdebug is 64 bit, but that's a problem (is something lampp executes a 32 bit binary?)
