我正在尝试在x64 Arch Linux上运行xdebug，但没有成功。我安装了它，现在当我尝试运行灯泡时，它说：
Failed loading /opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so:/opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so: wrong ELF class: ELFCLASS64
我做了一些搜索，发现我需要再次下载xdebug，将其编译为x64并将xdebug.so文件移动到lampp中的文件夹中。
How to use "make" to use 64 bit libs because of ELFCLASS64 error
我已经尝试根据第一个链接的指南编译它：
CFLAGS='-arch x86_64' ./configure --enable-xdebug
以及这些参数：
./configure --enable-xdebug "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32" --with-php-config=/opt/lampp/bin/php-config
但我遇到了这个问题：
configure: error: C compiler cannot create executables
See `config.log' for more details
这是config.log文件：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was
generated by GNU Autoconf 2.69. Invocation command line was
$ ./configure --enable-xdebug

我一直在寻找几个小时的解决方案，找到了一些类似的主题（比如this），但它没有帮助。
感谢您提出建议和意见。

在互联网上进行快速查询，结果发现，当我在64 bit Linux上运行时，我编译了64 bit xdebug.so版本的Xampp。
32 bit运行{{1}}所需的是预编译的32位版本。
我找到了解决方案here。

问题解决了。 :-)显然编译时出错：
/usr/bin/ld: cannot find -lgcc
我通过从官方的Arch linux multilib存储库安装gcc-multilib包解决了这个问题。
对于编译，我使用了以下参数：
./configure --enable-xdebug "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32" --with-php-config=/opt/lampp/bin/php-config
