good news

rainy day. I had a little time to test the latest trunk. SVN3899 no
longer segfaults

I started to look into that commit and there is quite a bunch of "bits". 
The bad news is that I'm unlikely to have time in the coming week. The 
good news is that I intend to take that laptop with me on our four weeks 
  holiday. I'll have a look as soon as I can.

I know Guido says he needs to fix this code, but since you have the 
hardware that fails, it would be very useful if you can figure-out 
which bit of this commit causes the segfault.

no. it built and started perfectly on the notebook where current trunk 
segfaults.

I guess next step is to try and build multiple version in between 3705 
and now until I find the commit that is segfaulting.

Got to run now, will take the notebook with me and try that sometimes later.

This suggests it is either a 32/64bit problem or a difference in 
OpenGL capabilities between the two machines.  The current trunk is 
ok for me on i386.

First you need to exclude one of the many recent OpenGL related 
hugin changes.  If you roll-back a couple of months (e.g to 3705) 
does it still segfault?

These warnings should be dealt with, but they are all problems that

The Boost library installed in your system uses the deprecated 
SGI hash_set container when it should use the TR1 unordered_set 
container. A bug report has been filed:

Install the LAPACK development package (liblapack-dev in 
Debian/Ubuntu) and edit the includes and Makefile to define 
HAVE_LAPACK and the library paths. Or ignore if you don't want 
to add another external library dependency.

Probably PrintError() should take a const char* parameter instead

some more information.

the previous report was from my notebook (32bit Ubuntu 9.04) for SVN3860.

I now built the same SVN3860 on my desktop (64bit Ubuntu 9.04) and 
everything works fine.

I was lucky to have a working Hugin on the notebook for 


Unfortunately I don't recall if it was built before or after the upgrade 
to 9.04. When I get back to that same SVN number now, it segfaults.

My conclusion out of this observation is that something has changed in 
the system / libraries - not in Hugin's codebase. But what is it and how 
do we deal with this?

Another thing that I noticed, on both systems, there are many many more 
warnings than a few weeks ago. Maybe somebody can make sense out of them:

This is a (recent) segfault on startup bug reported by several 
people here:

http://groups.google.com/group/hugin-ptx/msg/0ae8cc3d73960a4b
https://sourceforge.net/tracker/?func=detail&atid=550441&aid=2793279&group_id=77506

..and possibly this one too:

http://groups.google.com/group/hugin-ptx/msg/9fee1b36f6800713

I can't reproduce this, but it is effectively blocking a release.
