Compiling psqlODBC on Windows

This page describes how to build the PostgreSQL ODBC Driver on Windows. There are three methods to build: from command line using nmake makefiles, from command line using MSBuild files, and from Visual Studio IDE.

The following 3rd party software are required for the build:

For the MSBuild method, you will also need PowerShell.

It's also possible to build without libpq and OpenSSL, but some authentication methods will be disabled.

Building with nmake.exe

Use NMAKE.exe to build the driver for the currently active target:

C:\psqlodbc\> nmake /f win64.mak <options>

Despite the name, win64.mak is used to build both 32-bit and 64-bit binaries. With the Microsoft Windows SDK Command Prompt, you can switch between 32-bit and 64-bit target architectures with setenv /x86 and setenv /x64 commands. If using a Visual Studio Command Prompt you can start the x86 or x64 versions from the Start menu, or run vcvarsall.bat with appropriate options to switch architectures.

To build the .msi installer file:

C:\psqlodbc\> nmake /f win64.mak installer

The resulting installer file goes to installer/x64 or installer/x86 directory.

To build both 32-bit and 64-bit versions in one command:

C:\psqlodbc\> nmake /f win64.mak world

The following build options may be used, either on the command line, or by creating a file called "windows-local.mak".

Valiable Values
CFG Release(default), or Debug
PG_INC $(PROGRAMFILES)\PostgreSQL\9.3\include
PG_LIB $(PROGRAMFILES)\PostgreSQL\9.3\lib
SSL_INC C:\OpenSSL-Win32\include
SSL_LIB C:\OpenSSL-Win32\lib
LINKMT MT
ANSI_VERSION no (If set to "yes", output dll name to psqlodbc30a.dll)
MSDTC yes
USE_LIBPQ yes (libpq is required)
USE_SSPI yes (secur32 and crypt32 libraries are required)
USE_GSS no (gssapi library is required)

  1. UNICODE is the default (psqlodbc35w.dll), unless ANSI_VERSION is selected (psqlodbc30a.dll)
  2. libpq.dll is used supported.
  3. SSL and Kerberos are original equipment.
  4. ODBCVER becomes 0x351 when UNICODE is selected, or becomes 0x0300 with ANSI_VERSION == Yes.
  5. If MSDTC == Yes, "pgxalib.dll" is created.
  6. If MSDTC is enabled, ANSI_VERSION also creates "pgenlista.dll", or UNICODE creates "pgenlist.dll".

Building with MSBuild

See winbuild/readme.txt in the source directory for details.

IDE Method

A Microsoft Visual Studio project file (and workspace) is included in the source tree.

psqlodbc.dsp can be used with Microsoft Visual C++ 6.0.

psqlodbc.proj and psqlodbc.sln can be used with Microsoft Visual C++ 2005 Edition (including the Express edition which can be downloaded free of charge from http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/default.aspx)

Preparation before the build:

  1. The Windows distribution of PostgreSQL will install the required headers and libraries into C:\Program Files\PostgreSQL\9.2
  2. OpenSSL should be installed into C:\OpenSSL (OpenSSL binaries can be downloaded from http://www.slproweb.com/products/Win32OpenSSL.html)

If you want to change the installation arrangement, it is necessary to edit the project settings.

Note:

The default build settings will create the following driver:

  1. UNICODE support.
  2. libpq and SSL equipped are supported.
  3. Kerberos are supported peculiar by psqlODBC.
  4. ODBCVER is 0x0351.
  5. The driver filename is "psqlodbc35w.dll".
