Hello,

I am trying to build the gnat-gpl-2011-avr-windows toolchain in GPS with a =
simple project (which I do not expect to run on an AVR chip for now). So I =
have installed on Windows 7 machine the gnat-gpl-2011-i686-pc-mingw32-bin.e=
xe and the AVR gnat-gpl-2011-avr-windows-bin on c:\GNAT\2011.=20

I configured a GPS project file as

project Test is
   package Compiler is
      for Default_Switches ("ada") use ("-gnat05");
   end Compiler;

   package Ide is
      for Gnat use "avr-gnat";
      for Gnatlist use "avr-gnatls";
      for Debugger_Command use "avr-gdb";
   end Ide;

   for Source_Dirs use (".", "src");
   for Main use ("main.adb");
end Test;

When I try to build, it returns me

avr-gnatmake -f -d -PC:\test\test.gpr main.adb
avr-gcc -c -gnat05 -I- -gnatA C:\test\src\main.adb
avr-gnatbind -I- -x C:\test\main.ali
avr-gnatlink C:\test\main.ali -o C:\test\main
c:/gnat/2011/bin/../lib/gcc/avr/4.5.3/../../../../avr/bin/ld.exe: cannot fi=
nd -lc
collect2: ld returned 1 exit status
avr-gnatlink: error when calling C:\GNAT\2011\bin\avr-gcc.exe
avr-gnatmake: *** link failed.

[2012-04-09 00:13:05] process exited with status 4 (elapsed time: 00.25s)

So I included in GPS project file some options:

   package Linker is
      for Default_Switches ("ada") use ("-O", "-mmcu=3Davr6", "-nostdlib", =
"-lgcc", "-Wl,-mavr6,-Tdata=3D0x00800200");
   end Linker;

and now when I try to build it returns me

avr-gnatmake -f -d -PC:\test\test.gpr main.adb
avr-gcc -c -gnat05 -I- -gnatA C:\test\src\main.adb
avr-gnatbind -I- -x C:\test\main.ali
avr-gnatlink C:\test\main.ali -O -mmcu=3Davr6 -nostdlib -lgcc -Wl,-mavr6,-T=
data=3D0x00800200 -o C:\test\main
c:/gnat/2011/bin/../lib/gcc/avr/4.5.3/../../../../avr/bin/ld.exe: avr archi=
tecture of input file `b~main.o' is incompatible with avr:6 output
c:/gnat/2011/bin/../lib/gcc/avr/4.5.3/../../../../avr/bin/ld.exe: avr archi=
tecture of input file `C:\test\main.o' is incompatible with avr:6 output
collect2: ld returned 1 exit status
avr-gnatlink: error when calling C:\GNAT\2011\bin\avr-gcc.exe
avr-gnatmake: *** link failed.

[2012-04-09 00:15:00] process exited with status 4 (elapsed time: 00.25s)

Thus, what did I miss in setup? I just want to generate a .hex file for a d=
ummy main.adb.

Thanks.
