The one thing I thought that was unintuitive, is all the other tools had drop down widgets to make a choice on. I saw the 'gnatmake' there, but I couldn't see how to change it. After puzzling a bit and trying other stuff I gave a frustrated double-click on it, that suddenly brought up a new dialog box. That's unintuitive, because it doesn't look like it should work. Maybe it's just me. It's certainly a pain to have to go changing everything for each new avr project. So after playing with GPS a bit, I moved back to makefile and emacs. Warren

I'm interested in using some of the library support for it, so I gave it a go. But I ran into a problem in getting it to link: avr-gnatmake -Ptestavr.gpr avr-gnatbind -aIc:/WinAVR-20100110/lib/gcc/avr/4.3.3/rts/avr5/adainclude - aOc:/WinAVR-20100110/lib/gcc/avr/4.3.3/rts/avr5/adalib -I- -x F:\cygwin \home\Warren\avr\testavr\testavr.ali avr-gnatlink F:\cygwin\home\Warren\avr\testavr\testavr.ali -mmcu=avr5 -lgcc -o F:\cygwin\home\Warren\avr\testavr\testavr b~testavr.o: In function `adafinal': b~testavr.adb:(.text+0x16): undefined reference to `system__standard_library__adafinal' b~testavr.o: In function `main': b~testavr.adb:(.text+0x44): undefined reference to `__gnat_initialize' b~testavr.adb:(.text+0x54): undefined reference to `system__standard_library__adafinal' b~testavr.adb:(.text+0x58): undefined reference to `__gnat_finalize' avr-gnatlink: error when calling C:\WinAVR-20100110\bin\avr-gcc.exe avr-gnatmake: *** link failed. make: *** [testavr.ihex] Error 4 I also tried using the -RTS= parameter. If I leave out the -RTS= or the -aI and -aO options, it then complains about not being able to find -lgnat. I also tried -nostdlib, but that didn't seem to make any difference. There seems to be an undocumented step in configuring the platform. I would have thought that -mmcu=... would have taken care of that, but evidently it is not enough. Also: are you sure the parameter is '-XMCU=...' ? It didn't seem to matter when I used -mmcu=... (I tried both). Oh the fun in getting embedded stuff to work. ;-) Warren

Hmm. Huh? It does the -lgnat on its own. Adding it didn't helped either. ;-) Warren

The key turned out to be the following 3 lines in the project file (that I had differently): package Builder renames AVR.Builder; package Compiler renames AVR.Compiler; package Binder renames AVR.Binder; I'm not that familiar with all this gnat project file business, but I can see that I'll need to..
