Contents: - src.zip contains the source files used to compile the windows dependencies. I have not yet updated the mac dependencies for all of the latest released dependency files. Also, osgeo4w was removed sense it's binary only. I have not yet added libcurl,OpenSSL and fftw3 source and so these are still retrieved from osgeo4w. We may want to move to fftwss for it is lgpl with api compatability to fftw3. This is used by the registration plugin. - Visual Studio Express will contain both src and binary distribution - MacOSX contains just the binary distribution of the libraries. DOWNLOADING you should extract to a directory called ossim_dependencies that is parallel to the other ossim source modules.
