NeroLINUX is available!

NeroLINUX is now available at this page.

ChangeLog for this version:

(update) Fixed hang when erasing rewritable discs

Sometimes, when erasing a rewritable disc, NeroLINUX was freezing. This is now fixed.

(update) Fixed SELinux problem with NeroLINUX libraries

NeroLINUX package was not registering correctly the associated libraries with SELinux. The result of this was that, just after the splash screen was shown, the whole application crashes. This is now also fixed.

(update) Addition of SuSE Linux 10.0 in the supported distributions.

Hmmm only a bug fix :frowning: We need new features …

Great! :confused: However it crashed on FC4:

Can you check the /var/log/audit ? It seems to be related to SELinux

Hi mathf, thanks for the reply!

about selinux: nope, that mast be something else. I’m booting with ‘selinux=0’, and
`sudo grep ‘nero’ /var/log/audit*’ brings out 0 results.

Also, I would imagine that a good app should not crash once blocked by selinux. (i.e. kernel returns ERRNO 13 “Permission denied” on a some systemcall )
What I posted above is a crash.

let me know if you need more info.


Looks really weird… also we tested NeroLINUX on Fedora Core 4.

I looked around – It turned that out I’m running a newer version of glibc. Stock FC4 has glibc-2.3.5-10.3, mine has glibc-2.3.90-18

So, it would explain why you did not see the same results on your FC4 machine. However, my PC has a gazzillion application compiled against glibc, and by what ever reason they do not produce this


Let me know if I can help /-K.

ADD: my view is that nerolinux calls function munmap_chunk() which takes pointer as an argument. If you do not pass a valid pointer to that function it would through an error : invalid pointer:


why nerolinux passess an invalid pointer – I dunno. If you google around, this error is not common at all.

Huh… must come from somewhere else… we are not using this function inside our source code :disagree:

Hi mathf, Happy Holidays!

I’ve attached strace results, it looks rather interesting, if you have sources available, I think it may help.

Let me know if you need more info

nero_strace.txt (68.2 KB)

Hummm… can you provide me a gdb backtrace also?


gbd_trace.txt (5.44 KB)

Did you find a solution for this? I’m having the same problem on FC4.

for this bug, I have created a separate thread. Please have a look here :

I used NeroLINUX to burn an iso image file to a CD-R. As the md5sum
of the CD did not match the md5sum of the image file, I compared the two
and found that NeroLINUX has appended exakt 300kb of 0x00. How can I
turn this off. I think previous versions of NeroLINUX did not show this behaviour.

Thanks in advance for any hint!
