A. To configure and compile wvware in Greenstone2/3, it used to be required to first:
   source ./devel.bash

Now the above is done automatically when compiling up Greenstone 2 or 3.

However, if compiling gnome-lib manually (outside a Greenstone installation), then the above is still necessary to compile wvware and you need to add -fPIC to CFLAGS and CXXFLAGS:
   svn co svn co http://svn.greenstone.org/gs2-extensions/gnome-lib/trunk gnome-lib (**)
   export CFLAGS="-fPIC $CFLAGS"
   export CXXFLAGS="-fPIC $CXXFLAGS"
   source ./devel.bash

** NOTE: if you check out the gnome-lib/trunk folder as "gnome-lib", then its "src" subfolder is the one you'll want to be doing things like sourcing devel.bash/CASCADE-MAKE.sh, compiling and creating gnome-lib-minimal tarballs in.

Then follow from step B below onwards.


B. To compile up all of gnome-lib:
   ./CASCADE-MAKE.sh

C. To do a clean compile 
   At the toplevel, rm the <OS> directory completely
   ./CASCADE-MAKE.sh tarclean
   ./CASCADE-MAKE.sh
The second step removes all the extracted packages. While the third step extracts and recompiles them all again.
If you wish to just remove the intermediate files generated by configure and compile, then replace the 2nd step with
   ./CASCADE-MAKE.sh distclean  


D. To compile just a package in gnome-lib:
   source ./devel.bash
   ./packages/CASCADE-MAKE/<PACKAGE>.sh

E. To completely clean a single package and compile it up by itself
   (source ./devel.bash, unless you've already done it)
   ./packages/CASCADE-MAKE/<PACKAGE>.sh tarclean
   ./packages/CASCADE-MAKE/<PACKAGE>.sh
If you wish to just remove the package's intermediate files generated by configure and compile, then replace the 2nd step with
   ./packages/CASCADE-MAKE/<PACKAGE>.sh distclean  
   

F. To generate the gnome-lib-minimal-<os>.tar.gz archive file, 

1. Open a fresh exterm
2. make sure the gnome-lib folder (or it may be called "src") is renamed to "gnome-lib-minimal" first
3. source ./devel.bash
   from the gnome-lib-minimal folder
4. Also from the toplevel (gnome-lib-minimal) folder, run:
   ./CASCADE-MAKE.sh makeminimal
This will generate the tar.gz file. For ElCapitan and later MacOS, ensure the tar.gz file is named correctly. It may need to be moved into the folder containing the src subfolder. 
5. Check out trunk level of gnome-lib and put the tar.gz there:
   svn co --depth files http://svn.greenstone.org/gs2-extensions/gnome-lib/trunk/
(--depth files only checks out files at that level, not a recursive checkout of folders and subfolders)
6. svn commit the tar.gz file

This will generate a tar.gz file of the correct name. And because the gnome-lib folder had been renamed to gnome-lib-minimal in step 2, 
when the tar.gz file is extracted, it will extract as a folder called gnome-lib-minimal, as required.

Tested on the Mac MountainLion.


G. To generate the gnome-lib-<os>.tar.gz archive file

1. Open a fresh exterm
2. Make sure the top level gnome-lib folder is called "gnome-lib"
3. source ./devel.bash
4. toplevel
   ./CASCADE-MAKE.sh makedist
5. svn commit the tar.gz file
