使用unixODBC和FreeTDS問題連接到使用arm linux板的MSSQL數據庫

Question

我有問題從我的arm linux板上查詢遠程MSSQL數據庫。 我編譯了unixODBX和FreeTDS，把所有的文件都複製到arm板上，路徑和Ubuntu機器中的路徑相同，在那裏它們被編譯。 我也編譯了Ubuntu機器的所有東西。 在Ubuntu機器上，我可以用tsql和isql連接和查詢數據庫。 在arm板上，我只能使用tsql連接和查詢，而不能使用isql。

編制在Ubuntu機ARM板：

unixODBX：

./configure --prefix=/usr/local/unixodbc-arm --host=arm-linux 
make 
make install 

我刪除的/ usr /本地/ unixODBC的臂/斌/ odbc_config否則我便無法對其進行編譯。

freetds的：

./configure --prefix=/usr/local/freetds-arm --with-unixodbc=/usr/local/unixodbc-arm --host=arm-linux --disable-libiconv 
make 
make all 

我用--disable-libiconv的，因爲如果沒有這個選項是行不通的。

比我複製「bin」，「lib」和「etc」目錄中的文件到Ubuntu機器上的路徑相同。

/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 

的configuartion文件如下：

freetds.conf：

這些comman ds都在Ubuntu機器上使用相同的配置文件。

任何人都可以幫忙嗎？ 非常感謝。

從ISQL手冊頁...

ISQL DSN [USER [密碼] [選項]

DSN。數據源名稱，應該用於連接數據庫。按照該順序在/etc/odbc.ini和$ HOME/.odbc.ini文件中查找數據源，後者覆蓋前者。

帶有-S的Tsql正在使用您的freetds.conf文件。但它看起來像/usr/local/unixodbc-arm/etc/odbc.ini中的odbc.ini文件
