Hi Padraig,<br>
<br>
Does the segfault happen at the first call of
geometry->AddProjection(...) or later ?<br>
<br>
My guess is that, for some reason, geometry is not initialized. Can
you make sure it is by setting a breakpoint just before ?<br>
You should also make sure that all variables involved in this call,
ie "sid", "sdd", "angle", "isox" and "isoy" have reasonable values
before the call. <br>
<br>
It is probably not a good question, yet I have to ask : did you
modify something in the file
examples/FirstReconstruction/FirstReconstruction.cxx ? <br>

Following your advice I have tracked the seg fault down to
line 36 in FirstReconstruction<br>
<br>
geometry->AddProjection(sid,<br>
sdd,<br>
angle,<br>
isox,<br>
isoy);<br>
}<br>
<br>
</div>
I realised that I managed to build the examples with RTK fine
and the same example runs without a seg fault in the build
directory. <br>

With so little information, there isn't much we can do to
help you.<br>
I usually track segfaults by compiling in Debug mode (by
setting "CMAKE_BUILD_TYPE" to "Debug"), then running the
program in debug in QT Creator (any decent IDE will do
just fine, and should stop when the segfault occurs,
allowing you to trace it back)<br>
<br>
Good luck,<br>
Cyril
