Installing Connector/ODBC from a Source Distribution on Windows

You should only need to install Connector/ODBC from source on Windows if you want to change or modify the source or installation. If you are unsure whether to install from source, please use the binary installation detailed in Section, “Installing Connector/ODBC from a Binary Distribution on Windows”.

Installing Connector/ODBC from source on Windows requires a number of different tools and packages:

  • MDAC, Microsoft Data Access SDK from http://support.microsoft.com/kb/110093.

  • Suitable C compiler, such as Microsoft Visual C++ or the C compiler included with Microsoft Visual Studio.

  • Compatible make tool. Microsoft's nmake is used in the examples in this section.

  • MySQL client libraries and include files from MySQL 4.0.0 or higher. (Preferably MySQL 4.0.16 or higher). This is required because Connector/ODBC uses new calls and structures that exist only starting from this version of the library. To get the client libraries and include files, visit http://dev.mysql.com/downloads/. Building Connector/ODBC 3.51

Connector/ODBC source distributions include Makefiles that require the nmake or other make utility. In the distribution, you can find Makefile for building the release version and Makefile_debug for building debugging versions of the driver libraries and DLLs.

To build the driver, use this procedure:

  1. Download and extract the sources to a folder, then change directory into that folder. The following command assumes the folder is named myodbc3-src:

    C:\> cd myodbc3-src
  2. Edit Makefile to specify the correct path for the MySQL client libraries and header files. Then use the following commands to build and install the release version:

    C:\> nmake -f Makefile
    C:\> nmake -f Makefile install

    nmake -f Makefile builds the release version of the driver and places the binaries in subdirectory called Release.

    nmake -f Makefile install installs (copies) the driver DLLs and libraries (myodbc3.dll, myodbc3.lib) to your system directory.

  3. To build the debug version, use Makefile_Debug rather than Makefile, as shown below:

    C:\> nmake -f Makefile_debug
    C:\> nmake -f Makefile_debug install
  4. You can clean and rebuild the driver by using:

    C:\> nmake -f Makefile clean
    C:\> nmake -f Makefile install
  • Make sure to specify the correct MySQL client libraries and header files path in the Makefiles (set the MYSQL_LIB_PATH and MYSQL_INCLUDE_PATH variables). The default header file path is assumed to be C:\mysql\include. The default library path is assumed to be C:\mysql\lib\opt for release DLLs and C:\mysql\lib\debug for debug versions.

  • For the complete usage of nmake, visit http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vcce4/html/evgrfRunningNMAKE.asp.

  • If you are using the Subversion tree for compiling, all Windows-specific Makefiles are named as Win_Makefile*. Testing

After the driver libraries are copied/installed to the system directory, you can test whether the libraries are properly built by using the samples provided in the samples subdirectory:

C:\> cd samples
C:\> nmake -f Makefile all
