I know...vista...vista...
its still a pretty nice OS
and after its shoved down our throats by MS...
so i figured ill start learning it now
im impressed on how much stuf works...
course 2 things dont (avrstudio)
Im running with UAC off
the GCC compiler, I get this error
Compiling...
main.c
avr-gcc: _spawnvp: error: No such file or directory
anyone know what that means
i guess avr-gcc is a MFC based code
and that is spawn of some process
prob some path issue...
how would i bring this up with the authors?
thanks all

Of course not. ;-)

But yes, that's what it does. avr-gcc.exe is just the
compiler driver, and it wants to invoke cc1, [avr-]as,
and [avr-]ld. |

It's a plain command-line command.

No, you probably need to analyze that using a syscall
tracer. Are you sure it's installed correctly? I'd
read the "No such file or directory" error message as
if one of the child programs could not be found in the
expected locations. But of course, it could be that the
error message is just nonsensical. |

A wild guess:
In vista, the filesystem is by default in fsckup-mode. If you are used to XP, and install winavr, winavr won't get installed where you think it'll be installed, and the searchpath won't be set correctly. Instead of putting it in c:\winavr or in c:\program files\winavr, it will be put in an 'emulation folder' in your profile. This enables users to install/modify programs without changing things for other users. When you try to look at the filesystem you will see it as if the files are where they are supposed to be. If this emulation was done thoroughly it wouldn't be a problem, but it's only three-quarterway, and when the spawned process attempts to spawn another, information is lost somewhere.
Copy the winavr installer executable to your desktop, rightclick it, select run as administrator. You may think you are logged in as administrator, but you don't have the admin rights enabled UNLESS you do this. Wait for it to install.
Try if it works now. If not:
Create a shortcut to cmd.exe on your desktop, rightclick and run as administrator, and THEN you can likely invoke the compiler. You probably +edit: need to reboot+ after you install winavr. |

its for sure a PATH problem...
how does avr-gcc.exe know where the cc1.exe file is
and for that matter when all the standard includes are
having a path of "c\:avrgcc\bin"
it seems to work upwards and back in to other dirs to find files in XP
does not work in vista

I'm just trying to get this to work too.
It's a pain, whatever it is.
ou first get the cc1 / ld not found problem. If you add c:\winavr\avr\bin to the path it then complains about not finding ldscripts. Most odd.
Running the installer as Administrator didn't help for me. It does look like cygwin is not seeing paths correctly.
Does anyone know how that environment normally works? I.e. how does gcc-avr know where ld is?
edit: running cmd as admin doesn't help either. |

I've worked around it, not ideally, but in a hack it to make it work manner.
Using Process Monitor tool I can see which search paths are being explored and it's not looking in the right places. No idea why, no time to work out why.
This is what I believe I did to get it working for me:
From the directory above your makefile (build directory?) create a Vista symbolic link:
mklink /d avr \winavr\avr
From the directory with your makefile:
mklink /d ldscripts \winavr\avr\lib\ldscripts
Then copy files from:
c:\winavr\lib\gcc\avr\3.4.3\include to
c:\winavr\avr\include
Copy files from:
C:\WinAVR\lib\gcc\avr\3.4.3\avr5 to
c:\winavr\avr\lib\avr5
I'm using Atmel128 so I guess things might be different for others.
This very crude hack - obviously is not a fix. More a "I need this working now and can't be bothered to find a real fix" workaround.

Well.. i dont exactly follow your quick work around...
where is avr-gcc.exe looking for cc1.exe and others...

Oh yes, my path has this in it too. Sorry, missed that.
c:\winavr\libexec\gcc\avr\3.4.3;c:\winavr\avr\bin;C:\WinAVR\bin;C:\WinAVR\utils\bin; |

If you´ve got the toolchain working, it shouldn´t make any difference which of the AVRs you use. The controller type is defined in the makefile, after all.

Not poking fun at you, but why don´t you then use something that works? Like Win XP or Win 2K? |

Yes, well. Sometimes you have to test your products on the latest OS before others find it doesn't work.
There's a certain irony there... |

I fully agree with that.
I also don´t want to go into a lengthy discussion, but I thought you were trying to get avr-gcc and the toolchain working and not one of your products.

You just have to activate the index-service of Windwos Vista to get the AVR GCC working correctly.
(In my german vista it is called "Indexdienst", dont know the exact name of the english Windows Vista). |

Thanks for trying it out on Vista. I'm sorry I can't help as I don't have Vista.
FYI, AVR GCC in WinAVR is built using MinGW/MSYS, so it's nothing to do with any MS-based products.
I would be intersted to know exactly what directories avr-gcc is trying to search.

All workarounds here does'nt work with my Vista. Have anybody another solution?
Does anybody know whether the programmers of WinAVR work on a solution about this problem? |

WinAVR has noone like a "programmer". It has almost close to one
person who's just assembling that binary distribution, using open
source software from everywhere, and compiling and bundling it for an
easy Win32 installation. I wouldn't call that a programmer (within
that context), as he mostly doesn't touch the existing opensource
software.
So as you guys run into problems with GCC, you'd have to ask the GCC
developers for whether they are working on a solution on this. What
might really help you here is that this is most likely not only tied
to the AVR platform (which is of really minor importance to the GCC
folks) but probably to all Win32 (or Win64?) ports of GCC in general.
On the other hand, about the only purpose of Windows Vista (from what
I can read about it) appears to be the Microsoft platform to enforce
what they call "Digital Rights Management" (and what in fact appears
to be rather a money-printing guarantee for Microsoft and Holywood).
If you consider that the Free Software Foundation (who's the legal
owner of GCC) calls that "Digital Restrictions Management" because
it's the fundamentally opposite of their view of what your rights for
computer data and software should be, this might in fact drastically
lower the priority of a Windows Vista porting effort for GCC.
Just MHO, of course. |

I agree with Joerg on everything he said. My only addition is that I might suggest that you contact the MinGW project on SourceForge and ask them about their support for Vista. The MinGW project puts together a GCC toolchain for Windows hosts. This is what I use to build the core AVR cross toolchain for binutils, gcc and avr-libc.

Hi Mitch,
Hi Guys,
I've successfuly installed and compiled one project on MS Vista Enterprise with WinAVR20070122. You should create the following batch with PATH extensions to start the compiler modules:
Code:
@echo off
setlocal
set AVR=%ProgramFiles%\Atmel\WinAVR
set PATH=%AVR%\libexec\gcc\avr\4.1.1;%AVR%\bin;%AVR%\avr\bin;%AVR%\utils\bin;%PATH%;
set AVRALEXLIB=%CD%\..\lib
set AVRALEXCOMMON=%CD%\..\common
set AVRHEXDIR=%CD%\..\_hex
set DIRAVR=%AVR%
set DIRAVRBIN=%AVR%\bin
set TMP=%CD%\..\_temp
set TEMP=%CD%\..\_temp
echo ...
echo Running in %CD%
echo Entering now in a new Shell!
echo Type exit to escape from local!
cmd
endlocal
There my be also inlcude definition problems, if any
please post your help request here!
please test
cheers
