makemkvcon on fedora FC10 SIGSEGV

[vartista]

Hi There,

I've tried previously with 1.4.4 and now with 1.4.6 but I'm unable to run makemkvcon on Fedora 10:

Code: Select all

$ sudo  /usr/bin/makemkvcon info
001014:000000:0000 MakeMKV v1.4.6 beta linux(x86-release) started
Current action: Scanning CD-ROM devices
Segmentation fault

or sometimes with a different output:

Code: Select all

$ sudo  /usr/bin/makemkvcon info
001014:000000:0000 MakeMKV v1.4.6 beta linux(x86-release) started
Current action: Scanning CD-ROM devices
Current progress - 0%  , Total progress - 0%   
Current progress - 0%  , Total progress - 0%   
Segmentation fault

One suspicious thing is that I have to add an exception to SELinux after compiling and installing the makemkv libs:
message from SELinux: "The makemkvcon application attempted to load /usr/lib/libmakemkv.so.1 which requires text relocation."

Code: Select all

$sudo chcon -t textrel_shlib_t '/usr/lib/libmakemkv.so.1'

Running an strace did not help:

Code: Select all

gdb did not help either:

any ideas?

Thanks a lot

We can try to debug. We would need core dump and makemkv libs compiled on your system (I assume that you're getting the core dump when app crashes).

[vartista]

The core dump is too big to post here -> http://rapidshare.de/files/48091242/mak ... ar.gz.html

I can also confirm that I get the same exact behaviour on my other machine running FC9.

Would it help with a debug enabled version of makemkvcon executable? even without the source code one could see the stack.

Is it possible that I'm the only one with this problem on FC9, 10?

Thanks again,

[vartista]

Here's the entry I get in /var/log/messages:
makemkvcon[11132]: segfault at af1d7f ip 082192e4 sp 03b7e018 error 4 in makemkvcon[8048000+380000]

Hi. I am having pretty much the same experience on Fedora 11 64-bit

I do have a core I can upload if you have a ftp someplace.

Thanks.

ps Fedora 11's stock openssl also is lacking the elliptical curve crypto. So, I ended up just compiling the latest snapshot of openssl 1.0 from source and pointing makemkv at that.

[mike admin]

MakeMKV 1.4.7 should compile and run fine. Please confirm.

[vartista]

I can confirm that v1.4.8 works on FC10.
Thanks and you can close this thread.

btw great work with makemkv !
