How to build iODBC for macOS (formerly known as OS X and Mac OS X)

Copyright © 1996-2024 OpenLink Software [email protected]

Method 1: Using Project builder

This build method only works for Xcode 8.0 or newer.

This version of Xcode was first supported on macOS El Capitan (10.11), however the resulting binaries are backward-compatible with OS X Mavericks (10.9) and newer.

OpenLink uses build environments on macOS Mojave (10.14) and macOS Big Sur (11.x) to produce suitable notarized installers with graphical components.

To build iODBC components yourself, you will first need to install the latest Mac OS X Developer Packages, which you can download from http://developer.apple.com/tools.

Then, execute the following commands in a terminal session, to build all the frameworks and demo applications:

$ cd mac 
$ make

After building the iODBC libraries and applications, you have to install them on your system with the command:

$ sudo make install

This installs the iODBCinst and iODBC frameworks into —

/Library/Frameworks/iODBC.framework 
/Library/Frameworks/iODBCinst.framework

— and the test applications iodbctest and iodbctestw into —

/Library/Application Support/iODBC/bin

— and the iODBC Administrator and iODBC Demo applications in —

/Applications/iODBC

iODBC Administrator.app

Now that you have installed the iODBC frameworks on your system, you will be able to use ODBC applications or build your own applications using the iODBC API.

Once you have installed an ODBC Driver, you can configure and test a new ODBC DSN, using either the 32-bit Cocoa UI, which can configure and test any ODBC driver that is built in Universal mode —

/Applications/iODBC/iODBC Administrator.app

— or the 64-bit version, which can configure drivers that only support a 64-bit Cocoa UI —

/Applications/iODBC/iODBC Administrator64.app

Test DSN connection

Once you have configured a DSN, you will be able to make a connection using the iodbctest tool which is located at —

/Library/Application Support/iODBC/bin/iodbctest

Method 2: Using configure and make

The iODBC package can also be built like any other Open Source package not using any frameworks.

This build method still works with older versions of Xcode.

On OS X Yosemite (10.10) and newer, Apple removed a number of programs from their Xcode.app commandline installation, including autoconf, automake, libtool, and some other tools needed to build iODBC from a newly checked out GIT tree. We suggest using the HomeBrew package manager to install these tools, according to their documentation.

To build the libraries, open up a terminal session in Terminal.app or similar, and execute the following commands:

$ sh autogen.sh
$ ./configure
$ make

To install the header files and libraries in /usr/local, execute the following command as an administrator, and provide that user's password when prompted:

$ sudo make install

Note that, by default, this will build components that only run on the CPU type you are building on, so ppc on very old machines, x86 on early CoreDuo machines, x86_64 on recent Intel models, and arm64 on current Apple Silicon models.

You can also build iODBC components that support multiple CPU architectures — either Universal components that support ppc, x86, and/or x86_64; or Universal2 components that support x86_64 (including as emulated by Rosetta2) and arm64.

Mac OS X Leopard (10.5) and Mac OS X Snow Leopard (10.6)

The following commands will build a release of iODBC that supports Mac OS X Leopard (10.5) as well as Mac OS X Snow Leopard (10.6), on ppc (including as emulated by Rosetta), x86, and x86_64:

$ CFLAGS="-O -arch ppc -arch i386 -arch x86_64"
$ CFLAGS="$CFLAGS -isysroot /Developer/SDKs/MacOSX10.5.sdk"
$ CFLAGS="$CFLAGS -mmacosx-version-min=10.5"
$ export CFLAGS

$ sh autogen.sh
$ ./configure \
    --disable-dependency-tracking \
    --prefix=/usr/local/iODBC.universal

$ make
$ sudo make install

Mac OS X Lion (10.7) and OS X Mountain Lion (10.8)

The following commands will build a release of iODBC that works on Mac OS X Lion (10.7) and OS X Mountain Lion (10.8):

$ CFLAGS="-O -arch i386 -arch x86_64"
$ CFLAGS="$CFLAGS -mmacosx-version-min=10.7"
$ export CFLAGS

$ sh autogen.sh
$ ./configure \
    --disable-dependency-tracking \
    --prefix=/usr/local/iODBC.universal

$ make
$ sudo make install

OS X Mavericks (10.9) through macOS Big Sur (11.x) on x86 or x86_64 (including Rosetta2 emulation)

The following commands will build a release of iODBC that works on OS X Mavericks (10.9) through macOS Ventura (13.x), supporting other components built for x86 (through macOS Mojave (10.14), where Apple dropped support for 32-bit components) or x86_64 (including Rosetta2 emulation):

$ CFLAGS="-O -arch i386 -arch x86_64"
$ CFLAGS="$CFLAGS -mmacosx-version-min=10.9"
$ export CFLAGS

$ sh autogen.sh
$ ./configure \
    --disable-dependency-tracking \
    --prefix=/usr/local/iODBC.universal

$ make
$ sudo make install

macOS Big Sur (11.x) through macOS Ventura (13.x) on x86_64 (including Rosetta2 emulation) or arm64 (Apple Silicon a/k/a M1 or M2)

The following commands will build a release of iODBC that works on macOS Big Sur (11.x) through macOS Ventura (13.x), running on Intel (x86_64) or Apple Silicon (arm64 a/k/a M1 or M2):

$ CFLAGS="-O -arch arm64 -arch x86_64"
$ CFLAGS="$CFLAGS -mmacosx-version-min=10.9"
$ export CFLAGS

$ sh autogen.sh
$ ./configure \
    --disable-dependency-tracking \
    --prefix=/usr/local/iODBC.universal

$ make
$ sudo make install

Test DSN connection

Once you have installed an ODBC driver and configured a DSN, you will be able to make a connection using the iodbctest tool which is located at —

/usr/local/iODBC.universal/bin/iodbctest
