Segmentation fault

Hi all,

I have this situation.

Folder krpano. In this folder I have the krpanotools and one image for testing the tools.

I launch this comand on server Linux (Debian GNU/Linux 6.0.10):

./krpanotools makepano -config=templates/vtour-normal.config R0010001.JPG
and display this message:

segmentation fault

any idea?

Many thanks,
MiCH

Hi,

difficult to say... either that Linux system isn't compatible or there is some problem with the input file...

A crash (segmentation fault) is very uncommon.

Do the tools run when running them without any parameters?
Are other images working - or is the same image working on Windows or Mac?

Best regards,
Klaus

Hi,

when you get a crash just by this, then that Linux system isn't binary compatible.

Best regards,

Hi Karl,

he tested in Debian and in Ubuntu and he make me a question regard a librairies hormis glibc.

He ask me in which Linux distribution krpanotools is tested.


This is the reply from the sys admin:

nos admin unix ont testé la commande donnée sous Debian 7.8 (Wheezy, ldd (Debian EGLIBC 2.13-38+deb7u6) 2.13) et Ubuntu 14.04 (ldd (Ubuntu EGLIBC 2.19-0ubuntu6.5) 2.19), et obtiennent un segmentation fault à chaque fois. Avec quelles distributions ça a été testé et approuvé?

Vous pouvez aussi essayer de lancer la version 32 bit pour voir ...

Est-ce que le développeur peut indiquer ce qu'il faut comme librairies hormis glibc ?

strace sur Debian 6 Squeeze :
execve("./krpanotools", ["./krpanotools", "makepano", "-config=templates/vtour-normal.c"..., "R0010001.JPG"], [/ 18 vars /]) = 0
brk(0) = 0xffc000
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fd558fd1000
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fd558fd0000
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fd558fcf000

Glibc

Hi Karl,

the sys admin say that segmentation fault comes by GLIBC 2.14.

This the output:
./libffmpegsumo.so: /lib/libc.so.6: version `GLIBC_2.14' not found (required by ./libffmpegsumo.so)
linux-vdso.so.1 => (0x00007fff175fe000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00007f8662799000)
libc.so.6 => /lib/libc.so.6 (0x00007f8662437000)
/lib64/ld-linux-x86-64.so.2 (0x00007f8662b84000)

Is it really this the problem? The libraries GLIBC?

The sys ask the correct procedure to install GLIBC.

Can you help me?

Cheers,
MiCH

Hi,

the krpanotools itself requiring only GLIBC 2.4 or higher.
Only the GUI (which your output above is from) requires at least GLIBC 2.14.

Best regards,
Klaus
