#118: r.patch fails on WinGRASS RC6 and earlier
----------------------+-----------------------------------------------------
Reporter: cmbarton | Owner: grass-dev@lists.osgeo.org
Type: defect | Status: new
Priority: critical | Milestone: 6.4.0
Component: default | Version: unspecified
Keywords: |
----------------------+-----------------------------------------------------
Students in my class have just discovered that r.patch fails under
WinGRASS. The GUI won't launch and it gives an error from the command
line. The errors are none-specific in both cases, making it difficult to
understand what is going wrong. This happened on RC4 and is still a
problem on the new RC6 version.

Hi Michael,
could you please try again? because I just tried the command and it works
fine.
Thanks,
It's failed on several student machines here. I don't have a windows box,
but will ask others to try. One of the systems that it failed on is
running Vista. I don't know if another one is Vista or XP.

Hi Michael,
I think that Vista is the key. I build and test WinGRASS on XP, so I
cannot figure out how does it run on Vista. This links to an issue I
already pointed out in the list: it's a fact that any professionist or
scientist who works on Windows actually still uses xp or 2000, but the
future is on Vista, since new machines (specially notebooks) seem to not
work with xp, due to unreleased libraries for xp to manage new HD
architectures. Should we start to think to build on both Vista and XP, and
thus release two versions of WinGRASS? I think that, at least, we need to
intensively test on Vista.

I'm running winGRASS version 6.3.0RC6 on Vista. I configured GRASS with
the windows installer program. I tried r.patch using the spearfish
dataset, but when I
try to launch r.patch from the wxPython GUI's menus, I first get a
security alert which
prompts me to allow or deny r.patch.exe access to my computer. When I
press 'Allow', I
get the following error message:
This application has failed to start because libgrass_gis.6.3.0RC6.dll was
not found. Re-installing the application may fix this problem.
Then r.patch.exe crashes and Vista automatically kills it in the same
manner that it
would kill a hung program. The GUI seems to work fine afterwards.
When I run r.patch from the menu in the Tcl/Tk GUI, I get this error:
couldn't execute r.patch: invalid argument.
Running r.patch from the Output-Gis.m window fails without an error
message.
I've never touched Vista, but maybe until we fix the code, people could
try to use the XP compatibility mode [1], but I don't know how to tell
Vista to apply this to all grass .exe files without having to click on
every single one of them.
I tried switching r.patch.exe to XP (SP2) compatibility mode, but it
doesn't seem to help. I did, however, find libgrass_gis.6.3.0RC6.dll in
my lib directory, so that isn't the problem.

Thanks John,
I also tried with wxPython GUI on XP, and r.patch works fine.
As I figured out in past comments, this is only a Vista problem. I'm
afraid.
As I told some time ago, talking with Glynn, I think that we should start
to think to build also on Vista (even if Glynn doesn't agree). This will
be probably an available option on next month, when I'll buy a new PC (I
guess on June).

I think it is encouraged to build for testing using Vista, but to build
*for general distribution* using XP. That way one build should work for
everybody.

Hi John,
I just built GRASS 6.3.0 on Windows Vista (Home Premium) through the
MSYS/MinGW environment, exactly as I built it on XP. I made only few
tests, but both r.patch and v.patch worked fine for me.
This said, I don't think that it depends on the new build: I think that
the problem lies on the UAC system, because it forbids third party apps to
write outside the "Program Files" and "Users/Account Name" folders,
specially if the destination folder is directly in the unit root (such as
C:\), and sometimes even if the user gives the permission after the UAC
alert prompt message;
