SegmentationFault - Raspberry Pi

[loric-]

Hi,

I am trying to launch the Pi pre-compiled version of MCServer on my Raspberry Pi 512mo B and I have a SegFault when I launch the MCServer.

Rasberry Pi pre_compiled version

Is it normal? Do I miss something?

Here is the log

Code:

Thanks in advance

The precompiled version is known not to work on some RasPis. Can you try compiling it yourself?

Yes I could give it a try. How am I supposed to do that for the raspberry pi? Do I need to follow the Linux method of this the file below? (with cmake)

https://github.com/mc-server/MCServer/bl...MPILING.md

Or is there a makefile somewhere in order to launch a make?

Follow those Linux instructions, you most likely want the Release mode. In the first step (apt-get), you might need to add "g++" to the list of programs. (EDIT: I added g++ to the page)

Note that it takes between half an hour to a full hour to compile the server on a physical RasPi.

Thanks, it's working great with the manual compilation!

I am also experiencing a segmentation fault on a Model B Raspberry Pi with Raspbpian (MC server hardfloat). However, it occurs immediately when someone logs in. If no one logs in, the server runs fine.

I tried compiling by following the Linux instructions exactly, however that failed at the cmake step at 23%. I will post my exact compilation issue in a new thread.

The new issue is unrelated to the earlier one, as the earlier one was caused by Soft-Float compilation (now I added a hard-float build) but I don't know what this one is about. I see that you uploaded an issue to GitHub, so more conversation will probably go on there.

If the current failure was caused by 1.6.4 clients, you should get an updated version of MCS, it has been fixed.

Hi,
I am having some troubles with the MCServer build for raspberrypi.
I can launch the server with ipv4 and 6 and https certificate.
But when I join the server on the Minecraft client it says :
D: | MCServer has encountered an error and needs to close
Details: | SIGSEGV: Segmentation fault
What do I need to do ?

Hi, welcome to the forum.

Generally, there's a guide for reporting crashes on Linux (which is true for RasPi as well):
https://forum.cuberite.org/showthread.php?tid=631

Are you using a prebuilt binary, or are you compiling your own? If using pre-built, just give us the build number of the download ("latest" is no good, because that changes at least twice a day), if you're building your own, we'd need you to post the entire executable. Then of course the crashdump file itself. *Or* if you can do the autopsy yourself, as described in the thread, that would be immensely helpful.
