【问题描述】：
我在从我的 arm linux 板查询远程 MSSQL 数据库时遇到问题。 我编译了 unixODBX 和 FreeTDS，将所有文件复制到 arm 板上，其路径与编译它们的 Ubuntu 机器中的路径相同。 我还为 Ubuntu 机器编译了所有内容。 在 Ubuntu 机器上，我可以使用 tsql 和 isql 连接和查询数据库。 在arm board我只能用tsql连接查询，不能用isql。
在 UBUNTU 机器中的 ARM 板编译：
unixODBX：
./configure --prefix=/usr/local/unixodbc-arm --host=arm-linux
make
make install
我删除了 /usr/local/unixodbc-arm/bin/odbc_config 否则我无法编译它。
FreeTDS：
./configure --prefix=/usr/local/freetds-arm --with-unixodbc=/usr/local/unixodbc-arm --host=arm-linux --disable-libiconv
make
make all
我使用了 --disable-libiconv 因为没有这个选项是行不通的。
然后我将“bin”、“lib”和“etc”目录中的文件复制到与 Ubuntu 机器中相同的路径的 arm 板上。
/usr/local/unixodbc-arm/bin
/usr/local/unixodbc-arm/lib
/usr/local/unixodbc-arm/etc
/usr/local/freetds-arm/bin
/usr/local/freetds-arm/lib
/usr/local/freetds-arm/etc
配置文件如下：
freetds.conf：
root@ok335x:/# cat /usr/local/freetds-arm/etc/freetds.conf

有人可以帮忙吗？ 非常感谢。
