[Insight-users] Compiling ITK on Windows: PNG problems

[Luis Ibanez]

Hi Raghavendra


Did you searched for a png.dll  ?

Another possibility is that your png library is not
being rebuilt...

Have you tried with a clean build from scractch ?

-------

If you want to get around this and disable PNG
you can modify the CMakeLists.txt files in the
following directories:


1) Insight/Utilities/
    (remove  "png" in the SUBDIRS command) that
    will prevent png from being built

2) Insight/Code/IO
    remove PNGImageIO and PNGImageIOFactory from
    the list of sources.


Note that this is not a "solution", just a desperate
attempt to get around the real problem.

PNG is build nightly and continuosly in all the
platforms you see in the dashboard. So it is very
likely that the problem is related configuration
of your specific system.
