如何使用configure和make工具來指定使用64位庫？我認爲這是自動的，但我得到錯誤的ELF類。如何使用「make」使用64位庫，因爲ELFCLASS64錯誤
我想爲Ubuntu 64編譯Xdebug與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
的./configure看起來沒給我，廠名工作無差錯，我已經複製了配置的情況下，其相關：
