I were unable to run groundstation for some time now,
- deleted PpenPilot and /config/OpenPilot

did a git clone, then git checkout next.  , then build -j4 gcs  the build completes - but when running openpilotgcs.bin, after 10sec I get :

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted

please, if anyone have any idea what's going on ...

[peabody124]

I think you will need to run from Qt Creator and get a backtrace for more information.  I hadn't heard of this bug.

[XXL-Wing]

I built everything from scratch yesterday (on an Ubuntu box), GCS runs without problems here...
Did some of the libraries or tools change since your last git clone?
maybe check that...
Or, if you have a Linux box, check back the kernel trace (dmesg) for memory limit reached or start the GCS with strace to check what's giong wrong.

cheers
Mike

[Andre-K]

no relevant dmesg output - and yes, it builds and runs on my laptop too, just something went wrong on my workstation.

[XXL-Wing]

try a

ldd openpilotgcs.bin 

on both machines and check for differences in used libraries....

there are differences, but nothing that sounds any bells, both computers are Ubuntu 11.10 32bit.

[XXL-Wing]

hmmmm.. you're right, nothing that is obvious...

OK then next thing is try to start the GCS with strace

strace openpilotgcs.bin 

and then see what it tries to do before the crash

yes, I see "cannot allocate memory" ,
during the command "system monitor" indicates that memory use is raising from 27% memory (1,1GB)  to a,most 50% , - so 2GB should be free, before starting on the 9GB swap.

It's a high number...   and does not reflect the:

ok, then my next idea would be to compare the output of

ulimit -a

on both machines.

very interesting...
to checkup on things that are limitations for the user, just try to start the GCS as root with sudo and see if it is working then.....

[Andre-K]

same crash as sudo too. (and - my computer have been running for weeks, but at last kernel update or so, - I tried to run it right after rebooting as strange act of windows-nostalgia, - with no success.)

[XXL-Wing]

Eventuell ein Bug im GCS..
http://lists.trollte...5/msg00856.html
sonst scheint alles OK zu sein auf den Maschinen....

Looks like it possibly has something to do with the ModelViewGadgetWidget::CreateScene() routine (last part of our code before the crash.  Unfortunately, the default build has symbols turned off, so it will take some time for chasing stuff down.

Seems I remember that Peabody124 turned off the ModelView widget on Mac (another 64 bit system) as it was causing issues there too.  The model view works on 32 bit Linux (my Avatar is from screen grab of the model view window).

for what it's worth, this is 32bit Linux, and games, and other graphics, and OpenGL works fine.  - and - few months ago, GCS did too.

Hmmmm.... Others are not seeing this on 32 bits.  Can you try working your way forwards in Next and try to see when it quit working for you?  Just do git checkouts based on the date and work forwards till it quits working.

a bit more detailed info please..

Grab a fresh Git repo with the following commands:

git clone git://git.openpilot.org/OpenPilot.git CheckGCS
cd CheckGCS
git checkout next
git pull

After you have done the clone to get the repo, use the following command to get the last checkin before a given date on next instead of the latest code you got with the normal command of just "git checkout next".

git checkout `git rev-list -n 1 --before="2011-08-19 23:59" next`

Start with the date shown (the last public release on 8/19) and work forward by doing the command to get a set of files from a given date, build them, test.  If they work, move forwards a month at a time till the failure appears.  When it does, move backwards 2 weeks.  Successively move forward or back towards the failure and cut the span in half each time (2 weeks, 1 week, 4 days, 2 days, 1 day), till you find where the code quit working.

Make sense?

[Andre-K]

yes, will do then tell .. thanks.

even a build after  "git checkout `git rev-list -n 1 --before="2011-08-19 23:59" next`"   - fails to run.
I just need to assume there's something wrong with my QT /build process on the workstation. It does build - but the result don't work.
