Problem with d&c under Debian GNU/Linux 11 Bullseye

[WoodSTokk]

I updated my Debian to Bullseye (11) and want recompile Flightgear with download_and_compile.sh, but have a error.

Does everybody know whats wrong or missing here?

have you cleared out the cache and tried a clean build? you should be able to remove/rename the dnc-managed/build directory... when you run dnc the next time, it will recreate it and do its thing... you might also want to let dnc do the update thing so it can be sure you have all the needed libraries and tools installed...

FWIW: i always run dnc so it reconfigures every time... just to be sure... but i have had to clear the build directory a time or three, too...

[WoodSTokk]

Yes, because i had problems in the past. So i do allways start with --cleanup.

Code: Select all

./download_and_compile.sh -an -pn -b Release --cleanup --git-clone-default-proto=git ALL

At the start all dependencies will be checked and are okay, so no missing lib.

The error message says that the compiler itself hit some error, with something about a memory access failure. Do you have enough free memory? Are you building for amd64?

[FlugHund]

I've been waiting for months for this now. I've got the same problem but I don't have time to investigate plus segmentation faults are not my strong suit, to say the least.

The system it happens on is Devuan Chimaera which is based on Debian Bullseye. It happens on my Laptop as well as inside a VM. I've even tried different compiler versions, gcc 9.3.0 and 10.2.1. So it most likely is not an issue special to WoodSTokk's system. It does not always break at the same position (like 45 % in WoodSTokk's log) once it even went through. If I had time to investigate I wouldn't even know where to report it, fg-devel or on gcc's site. Mayhap clang works better here but I have never used that either. In any case I am very interested in a solution since I am maintaining a wiki page for compilation (http://wiki.flightgear.org/Devuan). Thanks!

I'm compiling on amd64, thats right and i think with 24GB RAM i have enough memory.

Thats what i have also observed. Sometimes SIMGEAR will be build, but building FGFS run into a error.

I'm also interested in a solution. Otherwise i can't further develope for Flightgear.

I've seen the same internal compiler errors on devuan with g++ 10. /etc/issue is "Devuan GNU/Linux 3", i don't know what Devuan name that corresponds to).

Forcing the use of g++ 9 seems to work. (I think this can be done with 'CXX=g++-9 ./download_and_compile.sh ...'. but haven't checked this.)

Here are the exact g++ versions on my machine:
g++-10 (Debian 10.2.1-6) 10.2.1 20210110
g++-9 (Debian 9.3.0-22) 9.3.0

and what compiler is being used...

interesting... ubuntu 20.04 comes with gcc 9.3.0 and i've not had any problems there... am currently building the latest next... gotta wonder what else has changed...

[WoodSTokk]

It must have to do with the code, because i had a run with

Code: Select all

LANG=C ./download_and_compile.sh -s -j4 -bRelease --cleanup -an -pn --git-clone-default-proto=git ALL

that compiled the version 2020.3.11 successfully.
Only the next branch for 2020.4.0 break with errors.

Currently i compiled with

Code: Select all

CXX=g++-9 LANG=C ./download_and_compile.sh -j4 -bRelease --cleanup -an -pn --git-clone-default-proto=git ALL

and it freaking works, thanks cgdae!

My compiler are:
gcc-10 (Debian 10.2.1-6) 10.2.1 20210110
gcc-9 (Debian 9.3.0-22) 9.3.0

internal compiler error: Speicherzugriffsfehler

may point to some problem with gcc-10 (as your success with gcc-9 would suggest), but, if you can, have memtest run overnight on this computer. Possibly in multithreading mode. Just to exclude hardware issues.
