2014.05.09 13:11 "Re: [Tiff] compiling for bigtiff?", by Edward Lam

As far as I can tell, Ubuntu 13.10 (saucy) is already running a bigtiff capable libtiff. According to

     http://packages.ubuntu.com/saucy/libtiff5

It's already using libtiff version 4.X so I don't think you should need to recompile libtiff. I would just ensure you have the default libtiff5 package installed through apt and then rebuild enblend as suggested.

Thanks for that info!

Maybe the problem why enblend doesn't try to use bigtiff is because of this problem:

enblend: /usr/local/lib/libtiff.so.5: no version information available (required by /home/kaefert/src/enblend/enblend.build_1049/bin/enblend)

Do you know how to solve this to make libtiff tell what version it is?

But it still fails to write an output tiff file that would be bigger than 4GB. Do I need some special configure switch to enable bigtiff?

libtiff4 will write a smalltiff file by default. Bigtiff is not a compatible format, you need to specifically ask for it. Swap:

   output = TIFFOpen( output_filename, "w" );

for

   output = TIFFOpen( output_filename, "w8" );

enblend will need to set this flag and I guess they'll need a bit of GUI to let people turn it on or off.
