The best way to check for this is to drop to a terminal and execute 'odbcinst --version'.</font> <br><font face="Arial,Helvetica"></font> <table BORDER COLS=1 WIDTH="100%" BGCOLOR="#FFFFCC" NOSAVE > <tr> <td>[root@p12 qt]# odbcinst --version <br>unixODBC 2.1.1 <br>[root@p12 qt]#</td> </tr> </table> <font face="Arial,Helvetica"></font><font face="Arial,Helvetica"></font> <p><b><font face="Arial,Helvetica">Downloading</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">You can get the source from <a href="http://sourceforge.net/projects/unixodbc">Source Forge</a>.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">You can get binary distributions from various places. One place to look is with the vendor of your operating system. You can also go to <a href="http://sourceforge.net/projects/unixodbc/">Source Forge</a> and take a look at the Home Page to see the availibility and location of binary distributions.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Whether you choose a binary distribution or source code depends largely upon your site policy and which operating system you are working with. I recommend the following;</font> <ul> <li> <font face="Arial,Helvetica">Mac OSX - use a binary distribution</font></li> <li> <font face="Arial,Helvetica">Others - use a source distribution (tar-ball NOT CVS)</font></li> </ul> <font face="Arial,Helvetica"></font> <p><br><b><font face="Arial,Helvetica">Installing From Source</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">There are two options when installing from source. You can install from a source distribution (a gzipped tar-ball) or from CVS. In either case you will find README files in the main directory which should help you build and install unixODBC.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">The unixODBC build process uses the GNU auto-tools. This will be a concern to you if you choose to build from CVS because you must start the build process with 'make -f Makefile.cvs' - this, in turn, uses the GNU auto-tools (i.e. automake, autoconf) to build a 'configure' script. Unfortunately; the GNU auto-tools can be very version sensitive. See the README file(s) for more on this if you plan to build from CVS source.</font> <br><font face="Arial,Helvetica"></font> <table BORDER COLS=1 WIDTH="100%" BGCOLOR="#FFFFCC" NOSAVE > <tr> <td>[root@p12 unixODBC]# make -f Makefile.cvs </td> </tr> </table> <font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">You do not have to 'make -f Makefile.cvs' when using a source distribution. Regardless of whether you choose to use CVS or a source distribution you will want to execute the 'configure' script with options appropriate for your needs.</font> <br><font face="Arial,Helvetica"></font> <table BORDER COLS=1 WIDTH="100%" BGCOLOR="#FFFFCC" NOSAVE > <tr> <td>[root@p12 unixODBC]# ./configure --help</td> </tr> </table> <font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">The 'configure' script will check your system for features of interest and build some make files as well as create some include file(s) which will ensure that unixODBC will build without errors and only with features supported by your operating system.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">At this point it is important to think about whether or not GUI tools are important to you (and your Users). The 'configure' script will try to detect support for the GUI applications in unixODBC and will build them if such support exists. unixODBC includes GUI tools based upon the Qt class library and GTK. The Qt based tools will be built if libqt*so can be found. Linux systems will probably have this. You can get this from <a href="http://www.trolltech.com">Troll Tech</a>.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Now you are ready to build the sources. Do this with the usual build sequence of commands.</font> <br><font face="Arial,Helvetica"></font> <table BORDER COLS=1 WIDTH="100%" BGCOLOR="#FFFFCC" NOSAVE > <tr> <td>[root@p12 unixODBC]# make <br>[root@p12 unixODBC]# make install</td> </tr> </table> <font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica"><font color="#FF0000">Mac OSX</font>: The Apple folks seem to be grappling with their support for the GNU auto-tools at the time of this writing. I recommend installing from a binary distribution of unixODBC. If you must install from source, and you are having problems with the GNU auto-tools, then you may want to try the qmake build. The qmake build process is not well documented at this time. People familiar with qmake should be able to build unixODBC with the included qmake project files.</font><font face="Arial,Helvetica"></font> <p><b><font face="Arial,Helvetica">Installing From Binary</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">RPM</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Various RPMs exist for unixODBC. The best idea is to use any RPM files you can from your O/S vendor. Typically RPM distributions break unixODBC into more than one RPM distribution such as; core, and GUI.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Mac OSX Disk Images</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">A binary distribution for OSX has recently become availible in the downloads section at <a href="http://www.codebydesign.com/DataArchitect">CodeByDesign</a>. This includes proper Mac installs. The install should be done in the following order;</font> <ol> <li> <font face="Arial,Helvetica">Qt Runtime</font></li> <li> <font face="Arial,Helvetica">unixODBC</font></li> <li> <font face="Arial,Helvetica">drivers in any order</font></li> </ol> <font face="Arial,Helvetica">Others</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Proper install packages are also avalible for other platforms such as the Debian package format for Debian Linux. Check with the O/S vendor.</font><font face="Arial,Helvetica"></font> <p><b><font face="Arial,Helvetica">Where Are Installed Files</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">The location for files vary somewhat depending upon how you installed unixODBC (source or binary) and which platform you installed on. Furthermore; the location can be changed during a source install by './configure --prefix='.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Typically;</font> <ul> <li> <font face="Arial,Helvetica">library files will go in /usr/lib or /usr/local/lib</font></li> <li> <font face="Arial,Helvetica">binaries will go in /usr/bin or /usr/local/bin</font></li> <li> <font face="Arial,Helvetica">system config files will go in /etc or /usr/local/etc</font></li> </ul> <font face="Arial,Helvetica">The system config files are;</font> <ul> <li> <font face="Arial,Helvetica">odbcinst.ini - list of registered drivers</font></li> <li> <font face="Arial,Helvetica">odbc.ini - system data source names</font></li> </ul> <font face="Arial,Helvetica">The location of the system config files can be changed by setting the ODBCSYSINI environment variable at run-time. The system config files can be edited using a simple text editor but it is recommended that you use the ODBCConfig GUI tool or the odcinst command-line tool because they will validate the reading and writing of these files while ensuring that the current location is used.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica"><font color="#FF0000">Mac OSX</font>: The OSX binary install will use; /usr/lib, /usr/bin, /Applications/Utilities and /etc.</font><font face="Arial,Helvetica"></font> <p><b><font face="Arial,Helvetica">Post Install</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">You now have an ODBC sub-system installed on your system(s). What is the system administrators role from here? The system administrator is the only person who can install and register ODBC drivers and create/edit/delete system Data Source Names (DSN).</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Drivers</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">Drivers should be installed and configured based upon the driver vendors instructions. Many drivers do not include a full install process - lacking the driver registration step. These drivers can be registered using the ODBCConfig GUI tool or the odbcinst command-line tool.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">System DSN</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">These can be created using the ODBCConfig GUI tool or the odbcinst command-line tool. ODBCConfig is the prefered method but not all drivers have a User Interface (U.I.) part.</font><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica"><font color="#FF0000">Mac OSX</font>: In some cases the ODBCConfig icon will not open. In such a case you should drop to a terminal window and use the open command.</font> <br><font face="Arial,Helvetica"></font> <table BORDER COLS=1 WIDTH="100%" BGCOLOR="#FFFFCC" NOSAVE > <tr> <td># open /Applications/Utilities/ODBCConfig.app</td> </tr> </table> <font face="Arial,Helvetica"></font> <p><b><font face="Arial,Helvetica">Summary</font></b><font face="Arial,Helvetica"></font> <p><font face="Arial,Helvetica">unixODBC implements an ODBC sub-system for a wide variety of platforms. unixODBC can be installed using; binary, source and source from CVS. Drivers can be installed using installation methods created by the driver vendor with unixODBC tools availible to fill any gaps.
