我尝试将 auth_mod_auth (3.0.0) 模块添加到我的 Slackware 13 (apache 2.2 & MySQL 5.0) 系统中。
我运行了 apxs 的常用命令行（如 BUILD 文件中所述）
apxs -c -L/usr/lib/mysql -I/usr/include/mysql -lmysqlclient -lm -lz mod_auth_mysql.c
但我收到以下错误：

似乎 mysql 库与代码期望的不匹配。我环顾四周，它似乎是该模块的最后一个可用版本，尽管它已经过时了（2005 年 6 月）。
有没有人用类似的设置让它工作？我已经调整了半天没有成功:-(

我在这里找到了答案：http://bugs.gentoo.org/show_bug.cgi?format=multiple&id=192391
它有效！ :-)
它在文件中更改APR_XtOffsetOf为。APR_OFFSETOF.c
