Satellite tracker crash on MacOs #1648

loewal · 2023-04-01T14:45:08Z

Compiled v.7.12 on MacOs Ventura.

Started with an empty workspace and added Satellite tracker
Crash with only: segmentation fault.

Did I start wrong...?

And similar on ubuntu:

Both crashes appear to be in getPipes, rather than the Satellite Tracker. I've been unable to reproduce this on Windows, Linux or Mac. Do other plugins such as the AIS Feature crash?

Does the problem occur with the release .dmg as well as your own build?

srcejon · 2023-04-12T15:55:43Z

If just your own build, make sure you do a:

make clean

first, to ensure everything is rebuilt.

loewal · 2023-04-12T15:58:31Z

I always start with a clean start and then git pull etc. So…make clean, is that useful then?

I use this script while in the Downloads folder: clear git clone https://github.com/f4exb/sdrangel.git cd sdrangel mkdir build cd build cmake -Wno-dev -DRX_SAMPLE_24BIT=ON .. make -j2 sudo make install cd ~/Downloads sudo rm -R sdrangel All plugins etc. are installed with Homebrew. The satellite feature is the only one that crashes.

If you start from an empty directory, then no need for make clean.

srcejon · 2023-04-12T17:04:08Z

Is it possible plugins from different builds are being mixed together?

Maybe do:

ls -l /opt/install/sdrangel/lib/sdrangel/plugins (or whereever you installed to)

And check the dates on the plugins match

loewal · 2023-04-12T17:09:20Z

They are all from April 11.

Hmm. Built using your above script, and it works OK. What version of gcc are you using?

gcc --version
gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0

srcejon · 2023-04-13T13:21:29Z

Can you also confirm exactly when it crashes and the exact steps you use.

Press Add feature
Press start in Satellite Tracker... then crashes or before?
Do you change any settings first?

loewal · 2023-04-13T13:55:58Z

Is it possible you built sgp4 library using gcc 11? If so, try rebuilding that.

Hmm. Running out of ideas.

What version of Qt is reported in SDRangel status bar? What version of Ubuntu?

Just tried Gcc 12 here and no problem.

Just rebuilt on Ubuntu 22.10 with gcc 12 and Qt 5.15.6 and still can't see the problem.

All I can really suggest is trying a debug build with cmake -DCMAKE_BUILD_TYPE=Debug ... then rerunning in the debugger, which should give the exact line the program is crashing on.

srcejon · 2023-04-13T19:03:04Z

Try the debug build on ubuntu, instead. As I can more easily reproduce that. Thanks

It's just an issue when optimisation is disabled. I'll take a look tomorrow, but for now, you can skip it with cmake -DENABLE_CHANNELRX_LOCALSINK=OFF

It gets (for me) even stranger.. The compilation on my Mac mini (Ubuntu) went fine. I will continue testing with the debugger. However, why do I see this error only on my iMac. Here I will add the string you mention below and let you know.

It gets (for me) even stranger.. The compilation on my Mac mini (Ubuntu) went fine. I will continue testing with the debugger. However, why do I see this error only on my iMac.

Probably because it's a different compiler (clang vs gcc) and has compiled that bit of code slightly differently.

??? I just plain old used "cmake -Wno-dev -DRX_SAMPLE_24BIT=ON" And I don’t get any compilation-errors anymore. Is there any logical explanation? I wanted to compile myself because a) I can learn things and b) the DMG has no support for the Adam Pluto. To make things easier: shall I make a pull-request for that?

It's because of the -DCMAKE_BUILD_TYPE=Debug option. That tells the compiler to compile slightly differently, which results in the error.

If you use -DCMAKE_BUILD_TYPE=Release you wont see the problem. Note that not specifying -DCMAKE_BUILD_TYPE defaults to Release.
