How can I make enblend use the right TIFF library that will allow TIFF
images bigger than 4GB? Or how can I make enblend tell the tiff library
to use this BigTIFF format?

I've added a compressed logfile of my enblend error with verbose output to my "stuff" folder -->
http://kaefert.is-a-geek.org/misc/hugin/360degree233pics_enblend-failure/stuff/long-run_verbose-output.txt.7z


The last debug lines before the memory error where:

enblend: info: loading next image: projectname0226.tif 1/1
enblend: info: assembled images bounding box: [(263273, 3602) to (266269, 7581) = (2996x3979)]

enblend: info: creating blend mask: 1/3 2/3 3/3


infering from the output after loading picture nr. 255 and before that, the next lines should have been:

enblend: info: creating blend mask: 1/3 2/3 3/3
enblend: info: optimizing 1 distinct seam
enblend: info: strategy 1, s0:
enblend: info: t = 1.085e+05, eta =    6, k_max =  32, 157 of 296 points converged
enblend: info: t = 8.135e+04, eta =    6, k_max =  32, 157 of 296 points converged
enblend: info: t = 6.101e+04, eta =    6, k_max =  32, 157 of 296 points converged
...

Maybe some hugin / enblend developer can make some sense out of this
information..

Title:
  enblend fails to blend large pano

Status in Enblend:
  Confirmed

Bug description:
  Enblend failed with:

  enblend --compression=LZW -m 1200 -w -f135659x3947+0+1091 -o pano8110_l.tif ....
  ...
  enblend: info: loading next image: pano8110_l0000.tif 1/1
  enblend: out of memory
  enblend: std::bad_alloc

  This is a simple 0.5Gpixel panorama I shot. And agreed, Hugin did warn
  me that it might take a lot of memory.

  The thing is: There is no other tool to stitch this with, so I'll have to make do with hugin and its toolset....
  I thought there was an "imagecache" that would swap parts of images to disk...
