Problem with GPS on Windows

Problem with GPS on Windows

[James Alan Farrell]

Hi all,
I hope a question on GPS is not too far off base here...

I've downloaded gnat 3.15p, GtkAda and GPS 2.1.0 (20041129) for work
at home.  I'm running Windows XP.

I seem to be having two problems:
1. GPS cannot find the compiler:
    When I attempt to build my project I get

    gnatmake -PD:\programming\ada\hellow.gpr -d 
   [2005-05-04 17:08:08] Invalid command

   I have the compiler installed at C:\gnat\bin (which was the 
   default.)  It is in my path in the environment variables,
   and when I run gnatmake in cmd it is found.

   I have edited the project properties to make the compiler
   c:\gnat\bin\gnatmake, and I get the error described below.  I 
   hack the project file to make that error go away, and I get

   c:\gnat\bin\gnatmake -PD:\programming\ada\hellow.gpr -d 
   gcc -c -g -o d:\programming\ada\hello.o -g -gnatA  \
   d:\programming\ada\.\hello.adb
   gnatmake: error, unable to locate gcc

   It seems clear that GPS cannot is not reading the path.  So 
   where does it look for the compiler, and how do I set it on 
   the correct path?  (pun intended ;)

2. Something seems incorrect with the project file:
    When fixup the compiler command above to find gnatmake
    I get the error:

   undefined attribute "Executable"

   This line is highlighted in the project file:

   for Executable ("hello.adb") use "";

   When I remove this line and build from cmd, the program 
   builds fine.  So why is this line being put in, and how can I
   stop it?

   I created the project using the GPS project wizard.

Thanx,
James Alan Farrell

I don't know about that, but the relevant attributes are (eg)

  for Main use ("stairwell_demo");

  for Exec_Dir use ".";

(some versions of GPS needed the .adb extension on the main, I think
this is fixed now).

Personally I would rather edit the project file with a text editor,
having seen some truly mangled results! Never tried the wizard ..
