Gnat and Vista

Using Gnat Under VISTA

• An earlier version of Gnat needed special installation (given below) to work correctly under Vista. This may have been fixed in the 2008 version of gnat.


• Vista users: If you have problems using gnat, either from the command line or from an IDE, you may need to add one of the gnat libraries to your path. To do this, follow these steps:
1. Open your Control Panel
2. Open System icon
3. Select Advanced tab
4. Press Environment Variables button
5. In System variables, find Path and then click Edit
6. In the edit text box for the variable value, add the following to the end of the line:

       ;C:\Program Files\GNAT\2008\libexec\gcc\pentium-mingw32msv\4.1.3\ 
        

• Don't miss the semicolon (ie ";") in the line above
• Notice that the value of PATH is a list of folders, separated by semicolons. These folders are searched when the OS is looking for a command.
• This assumes that you installed GNAT in the folder Program Files


7. Click OK to close things and you are done. Gnatmake should work for AdaGIDE, GPS, and for the command line. (For it to work on the command line, you have to open the cmd window AFTER you do the above steps.)


• If you open a command window after you have done the above steps, you should be able to see the folder given above on your path. You can check the value of your PATH in a command window by doing

    echo %path%
