Building With GNU Auto Tools (by Nick):

	It looks as if Darwin (Mac OSX) doesn't support the normal
	dlopen type process that unixODBC requires. However help is
	at hand in the form of dlcompat-20010831.tar.gz. This file
	contains wrappers to emulate the calls. I have put this in
	
	ftp://ftp.easysoft.com/pub/beta/unixODBC/dlcompat-20010831.tar.gz
	
	It should be downloaded, unpacked then run make install
	
	This should be done before configuring unixODBC
	
	This file was created by Christoph Pfisterer <cp@chrisp.de> and
	the original copy can be found at 
	
	    http://fink.sourceforge.net
	
	If you get a "ld: multiple definitions of symbol " error, 
	then you should edit the file libtool in the unixODBC base 
	directory and find the line
	
	    whole_archive_flag_spec="-all_load \$convenience"
	
	and replace it with
	
	    whole_archive_flag_spec=
	
	As at the time of writing, Qt is not available on OSX, its best to
	disable the search for X libs that may fail, by configuring with
	
	    ./configure --enable-gui=no


Building With Qt qmake (by Peter):

	Qt is now availible for OSX but unixODBC may not detect your Qt
	libs... worse yet you may not be able sort out the GNU auto-tools
	required to build on OSX.
	
	If you want to build using qmake then read README.qmake.
	

Creating Install Packages:

	unixODBC contains a number of directories and files to help create
	OSX Packages. The process of doing so is not nearly as automated 
	as creating RPM files using the GNU auto tools. Look for the
	mac-install and mac-package directories.

Cursor LIB

The cursor lilb needs a manual stage build to create it as a OSX bundle
it needs to be like that so the DM can load it at run time.

To do this, after the "make" and "make install" have finished, go to the
cur directory in the build tree. Then there issue these commands

cc -bundle -flat_namespace -undefined suppress -o libodbccr.1.0.0.so *.lo
cp libodbccr.1.0.0.so /usr/local/lib/libodbccr.1

Replace /usr/local/lib/ in the above with whatever your actual unixODBC 
lib path is.

You may also have to do the same with any driver you build. You can check
this by testing the type of the lib, for example.

file /usr/local/lib/libodbcpsql.2.0.0.so
/usr/local/lib/libodbcpsql.2.0.0.so: Mach-O dynamically linked shared library ppc

This is not the correct type.

So to get it as you need :-

cd Drivers/Postgre7.1
cc -bundle -flat_namespace -undefined suppress -o libodbcpsql.2.0.0.so *.lo
cp libodbcpsql.2.0.0.so /usr/local/lib/libodbcpsql.2.0.0.so

Now to check

file /usr/local/lib/libodbcpsql.2.0.0.so
/usr/local/lib/libodbcpsql.2.0.0.so: Mach-O bundle ppc

Thats how it should be to work under the driver manager
