Trying to export large-ish segmentations makes Seg3D2 crash (538x548x1851), which is incredibly annoying when you have been doing a hand segmentation for a while, so I'm going to give Qt 4.7 a try.

(I'm on ubuntu 12.04, with Qt 4.8.1)

This happens both when I try to export from the File menu or with the right-click menu on the layer.
 I have downloaded the code and I'm building it, but how can I install it somewhere Seg3D2 will find it at compilation time, but won't interfere with the rest of the system?

OK, so I have installed Qt 4.7 to /usr/local/Trolltech/Qt-4.7.4

I have found in

seg3d.2.1/src/CMakeLists.txt

a line that says:

# We need QT - We use a modified version of
# the FindQt4.cmake file that can be set
# to search for different versions of QT
# just point QT_DIR to the right directory
# to skip the use of the default installed
# QT distribution.

This looks good, so I have edited the line below as

SET(QT_DIR "/usr/local/Trolltech/Qt-4.7.4" CACHE PATH "Path to QT")

However, it seems that ./build.sh completely ignores src/CMake/FindQt4.cmake

The build doesn't even enter that file, so regardless of what we have in QT_DIR, my Qt 4.8.1 is detected and used instead.

Cheers,

Ramon.
