The 64 bit version of the Microsoft SQL Server ODBC Driver for Linux CTP provides robust data access to Microsoft SQL Server.

Microsoft SQL Server ODBC Driver for Linux allows native C and C++ applications to leverage the standard ODBC API and connect to Microsoft SQL Server 2008 R2. Microsoft SQL Server ODBC Driver for Linux CTP also comes with powerful tools - sqlcmd and bcp.

Requirements to use the Microsoft SQL Server ODBC Driver for Linux:

- 64-bit Red Hat Enterprise Linux 5.x, with the following packages:
- glibc 2.5, the GNU libc libraries
- libgcc 4.1.2, GCC version 4.1 shared support library
- libstdc++ 4.1.2, GNU Standard C++ Library
- e2fsprogs-libs 1.39, Ext2/3 file system-specific static libraries and headers (provides /lib/libuuid.so.1)
- Krb5-libs (Kerberos shared libraries)
- Generic Security Services Application Programming Interface (GSS-API)
- OpenSSL
- 64-bit UnixODBC 2.3.0 Driver Manager, built for 64-bit SQLLEN/SQLULEN

Once you have downloaded the Microsoft SQL Server ODBC Driver for Linux CTP, you can validate the integrity of your download by running a checksum in either of the two manners:

1. Make sure that you have root permissions.
2. Navigate to the directory where you downloaded sqlncli-11.0.1720.0.tar.gz and extract it:
 cd ~/Downloads/
 tar xvf sqlncli-11.0.1720.0.tar.gz.
3. Change to the sqlncli-11.0.1720.0 directory, where you can run build_dm.sh to install the unixODBC Driver Manager:
 cd ./sqlncli-11.0.1720.0
 ./build_dm.sh --help
4. You can install the driver manager by executing the following command:
 ./build_dm.sh
 Note: you can also download the driver manager manually at http://www.unixodbc.org/ and use the downloaded archive locally:
 ./build_dm.sh --download-url=file://unixODBC-2.3.0.tar.gzli>
5. Type "YES" to proceed with unpacking the files. This part of the process can take up to five minutes to complete.
6. After the script stops running, follow the instructions on the screen to install the unixODBC Driver Manager.

1. Make sure that you have root permissions.
2. Navigate to the directory where you downloaded sqlncli-11.0.1720.0.tar.gz and extract it:
 cd ~/Downloads/
 tar xvf sqlncli-11.0.1720.0.tar.gz.
3. Change to the sqlncli-11.0.1720.0 directory, where you can run install.sh to install the driver:
 cd ./sqlncli-11.0.1720.0
 ./install.sh --help
4. (Optional) You may want to make a backup of odbcinst.ini. The driver installation will update odbcinst.ini. odbcinst.ini contains the list of drivers that are registered with the unixODBC Driver Manager. Execute the following command to discover the location of odbcinst.ini on your computer:
 odbc_config –odbcinstini.
5. Before you install the driver, you may run a verify step to check if your computer has the required software to support the Microsoft SQL Server ODBC Driver for Linux:
 ./install.sh verify
6. When you are ready to install the Microsoft SQL Server ODBC Driver for Linux CTP, run the install script:
 ./install.sh install
7. After reviewing the license agreement, type "YES" to continue with the installation.
8. Verify that Microsoft SQL Server ODBC Driver for Linux CTP was registered successfully:
 odbcinst -q -d -n "SQL Server Native Client 11.0"
