[Gdal-dev] GDAL nix build configuration

[William Kyngesburye]

On OSX (I assume because of the dylib), it's simple to do without any  
patching of the GDAL make setup.  Let it build how it wants to and  
install it.  Then postprocess the library with install_name_tool.   
Assuming the default /usr/local install (and assuming that the  
compatibility problem is really that bad - Frank might know better on  
that score), that would be:

install_name_tool -id /usr/local/lib/libgdal.1.X.Y.dylib /usr/local/ 
lib/libgdal.1.X.Y.dylib

where X and Y are the minor and revision numbers matching what was  
installed.

You can change existing programs to match the new name with  
install_name_tool.  Like the GDAL tools, since they're built with the  
simpler version names.  Use otool first to verify the names:

otool -L /path/to/program

use the libgdal name there in install_name_tool:

install_name_tool -change /existing/libgdal/name /usr/local/lib/ 
libgdal.1.X.Y.dylib /path/to/program

[Marvin]  You think you have problems?  What are you supposed to do  
if you ARE a maniacally depressed robot?  No, don't try and answer,  
I'm 50,000 times more intelligent than you and even I don't know the  
answer...
