Overview of Installing and Using JEWL

• More details are in README.txt (not readme.txt).


• Windows Only: JEWL only works on windows!
• Win_IO provides simple GUIs. It is build upon GtkAda.
• GtkJEWL is patterned after JEWL and uses GTK, and so it is designed to work on windows and linux, but I was unable to get it to compile. Perhaps it is designed for an older version of Gtk or GtkAda.


• Download the zip file using the links listed above and expand the zip file.


• Make the JEWL files available to GNAT:
• The simplest method is to simply copy all of the files in the source directory into the directory where you are developing your JEWL client.


• An alternative to make JEWL available from any directory is to you can set up environment variable GPR_Project_File and to use project files. More details are in README.txt (not readme.txt).


• The examples in the examples directory show you some of JEWL's capabilities. Compile all of them using the command gnatmake -P all_test.gpr.

Making JEWL Work - These instructions are probably no longer needed!

• You should be able to ignore these instructions.


• To make JEWL work with the latest version of gnat, you may have to make the following change. In directory source change the file jewl-win32_interface.adb as follows. Replace this line:

 
        pragma Linker_Options ("-luser32 -lgdi32 -lcomdlg32 -lwinmm");
    

with these lines:

 
          pragma Linker_Options ("-luser32");
          pragma Linker_Options ("-lgdi32");
          pragma Linker_Options ("-lcomdlg32");
          pragma Linker_Options ("-lwinmm");
