Obtaining a Source Code Package, ODBC Packages, and Dependent Libraries

You need to obtain the unixODBC source code package, ODBC packages, and dependency libraries for ODBC-based development.

Obtaining the Source Code Package

To obtain the unixODBC source code package, visit https://www.unixodbc.org/unixODBC-2.3.7.tar.gz.
To obtain the MD5 file, visit https://www.unixodbc.org/unixODBC-2.3.7.tar.gz.md5.

Use the MD5 file to verify the integrity of the unixODBC source code package. (Check whether the MD5 value is the same as that in the source code package.)

Obtaining ODBC Packages and Dependency Libraries

ODBC packages and dependency libraries support both Linux and Windows systems. Obtain the required files based on the OS you use.

For Linux:
Obtain the package GaussDB-Kernel-Database version number-OS information-64bit-Odbc.tar.gz from the driver package. In the Linux OS, unixODBC header files (including sql.h and sqlext.h) and the library libodbc.so are required in application development.

The header files and the library can be obtained from the unixODBC-2.3.7 source code package.
For Windows:
Obtain the package GaussDB-Kernel_Database version number_Windows_X86_Odbc.tar.gz (32-bit) or GaussDB-Kernel-Database version number-Windows-X64-Odbc.tar.gz (64-bit) from the driver package.

In the Windows OS, the required header files and library files are system-resident.
