Hi Julien,
I have libtiff 4.0.0.dev-91 installled on Win7x64, and running
tiffinfo yields the same R6034 error you mention. Also like you,
gdalinfo (GDAL 1.8.1, released 2011/07/09) has no apparent problems. I
don't have Visual Express.
Glad to hear I'm not alone !
Running "dir /b/s c:\msvcr90.dll" found 31 copies of that file on my
system (see attached).
Changing PATH in the o4w command shell to simply
"PATH=c:\o4w_py27\bin", changed the tiffinfo error message to "The
program can't start because MSVCR90.dll is missing from your computer.
Try reinstalling the program to fix this problem". Extending path to
include an o4w package containing msvcr90.dll, e.g. qgis, makes
tiffinfo go back to the R6034 error. Gdalinfo continues to run fine;
maybe this is because gdalinfo actually relies on libgeotiff and not
libtiff?
From the msvcrt-1.0.1-5 o4w package I extracted vc_red.cab from
vcredist_2008_x86.exe (using 7zip), and then put each kind of dll into
it's own directory, renamed as expected. So "nosxs_msvcr90.dll" to
".\vc2008_nosxs\msvcr90.dll" and "msvcr90.dll.30729.*.sp" to
".\vc2008_30729\msvcr90.dll", etc. I then added each of those
directories to path in turn (solo, not additive) and ran tiffinfo:
R6034 errors in all cases.
I repeated this with the msvcrt-1.0.1-4 package and got identical
results.
I then extracted libtiff-4.0.0dev-91.tar.bz2 into d:\libtiff-dev91,
and from a command shell with a minimal o4w path
(PATH=c:\o4w_py27\bin) ran tiffinfo, got R6034.
Repeat with libtiff dev-90: WORKS -- yet there aren't any msvc*90.dll
in PATH (!)
The dev-90 package depends on msvc*71.dll (Visual 2003) and does not
depend on msvc*90.dll, so no problem here.
But the worst thing is that these msvc*dll are handled differently than
the other dlls (they can be found in this winsxs folder while it is not
in the PATH).
I deleted PATH altogether: dev-90 tiffinfo complains of missing
'jpeg_osgeo.dll', and then 'zlib_osgeo.dll'.
I copy those from c:\o4w_py27\bin into d:\libtiff-dev90: tiffinfo
works again.
So it looks to me like libtiff-dev91 thinks it requires something fomr
msvcr*.dll, when it actually doesn't, but won't carry on until the
mistaken assumption is cleared. Or something.
The dev91 package *does* require msvc*90.dll, but does not accept the
ones used by other packages.
Anyway, cleary libtiff-4.0.0dev-91.tar.bz2 is broken and should be
replaced or removed from the package repository if it can't be fixed.
OK same conclusion for me : there is something wrong with the dev-91 build.
As I never understood anything about those manifest/runtime issues with
visual c++, I'm unable to further locate the problem.
All your tests are coherent with what I see on my side.
Thanks for all this intensive testing.
I hope something in all this helps!
Now I know it does not come from my machine, and this is good information ;)
Julien
