那位用过unixodbc?一个应用连接时调用了odbc库,格式如 -lodbc,可是在相应的/usr/local/unixODBC/lib/下没有libodbc.a(整个系统中也没搜到),只有一个文件libodbc.la(内容见内),该目录下有相应的动态库.连接能成功,WHY?

该系统是Redhat9. 似乎安装unixodbc需要glib_devel的支持,因为在HP和Solaris下编译总提示少些头文件.那位知道安装unixodbc需要那些支持库? -mike20030405(mike); 2005-7-28 (#2422491@0)

sorry, glibc_devel -mike20030405(mike); 2005-7-28 (#2422527@0)

高手呢?都休假去了吗? -mike20030405(mike); 2005-7-28 (#2422872@0)

不是有libodbc.so嘛？ -holdon(again); 2005-7-28 (#2423259@0)

看来我以前理解有问题.动态库(如libodbc.so.1.0.0)也可以在连接时载入."在默认情况下，Linux将首先搜索指定库的共享版本，如果找不到，才会去搜索静态版本".谢谢! -mike20030405(mike); 2005-7-29 (#2424271@0)
