Question

如何使用configure和make工具指定使用64位库？我认为这是自动的，但我错了ELF Class。

我正在尝试为Ubuntu 64编译Xdebug，以便与LAMPP（XAMPP for Linux）一起使用。

./lampp start 

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

./configure对我来说看起来不错，并且make工作没有错误，我已经复制了配置，以防相关：

Answer 1

我不确定错误，但为什么要编译xdebug？它在Ubuntu的存储库中可用作php5-xdebug（sudo apt-get install php5-xdebug）。虽然你没有提到你的发行版，也许它的名字相似？

但是要回答你的问题，错误信息看起来像xdebug 64位，但这是一个问题（是什么灯泡执行32位二进制文件？）

Answer 2

不会：

LD_LIBRARY_PATH=/lib64:$LD_LIBRARY_PATH ./lampp start

工作？我不使用Ubuntu，所以你的路径可能会有所不同。一件事是

ldd ./lampp

查看默认可执行文件指向的内容。

Answer 3

尝试指向32位库，LD_LIBRARY_PATH=/lib32:LD_LIBRARY_PATH。

如果不起作用，请尝试64位库，LD_LIBRARY_PATH=/lib64:LD_LIBRARY_PATH。

完成命令：

sudo ./configure --enable-xdebug --with-php-config=/opt/lampp/bin/php-config LD_LIBRARY_PATH=/lib32:LD_LIBRARY_PATH

Answer 4

xdebug正在以32位编译。使用以下方法编译它：

CXXFLAGS="-m64" CFLAGS="-m64" LDFLAGS="-m64" ./configure --enable-xdebug

在SPARC Solaris 10上为我工作。

Answer 5

可能运行时链接程序的库路径错误。目录/ opt / lampp / lib64是否存在？ lampp是shell脚本吗？如果是这样，它设置LD_LIBRARY_PATH变量的值（以及是否）？
