Compile minidlna on debian, run on nas : libavutil conflict
Guys,
I have decided to try and create a development environment for the readynas (x86) to see if I can
get extend the current minidlna implementation and run it on the readynas directly.
Open issues which I am trying to solve are:
*) Multiple instances is not possible due to sharing of UUID
*) Using hidden ('.') file specific album art in addition to the others
*) Potentially : adding custom icon rather than the embedded 'N' logo or tux (per instance a different one)
I have created a development environment based on debian etch, installed the tools needed
for compilation and installed the prerequisited for minidlna.
I can successfully compile and run the generated minidlna executable on debian.
However, I do have problems running the executable directly on the readynas:
Gorgoroth:/c/home/root/etc# /c/shared/minidlna/minidlna-1.0.24/minidlna
/c/shared/minidlna/minidlna-1.0.24/minidlna: error while loading shared libraries: libavutil.so.49: cannot open shared object file: No such file or directory
Gorgoroth:/c/home/root/etc# ldd /c/shared/minidlna/minidlna-1.0.24/minidlna
.. snip, all ok ..
libavutil.so.49 => not found
.. snip, all ok ..
Gorgoroth:/c/home/root/etc# ls -lsa /usr/lib/i686/cmov/libavutil.so.*
0 lrwxrwxrwx 1 root root 20 2012-01-20 13:24 /usr/lib/i686/cmov/libavutil.so.50 -> libavutil.so.50.15.1
36 -rw-r--r-- 1 root root 34472 2011-07-01 19:55 /usr/lib/i686/cmov/libavutil.so.50.15.1
So, on the debian the libavutil (ffmpeg) is available in version 49, and on the nas its 50.
How to compile minidlna on the debian box so I can run the generated executable on the nas ?
Do I need to get minidlna compiled on the debian using libavutil.so.50 ? and if so, how (I could not find that version for etch)?
Should I just copy the 49 version onto the nas and hope all will be ok ??
Any ideas how to resolve this ?
Fred
p.s. A possible solution would be compile on the nas, but I do not have a spare nas to put all the needed packages on.

- You can:
1) Make a softlink of libavutil.so.49 to /usr/lib/i686/cmov/libavutil.so.50.15.1 and make sure your LD_LIBRARY_PATH is set to /usr/lib/i686/cmov/ and try again and hope for the best
or
2) Do a static build of minidlna so you don't have shared library dependencies on the target system:
2.1) Install the dev counterparts of the libriaries required by minidlna so that you have the headers ( .h ) and static versions of the libraries (i.e. the static library of libavutil would be in libavutil-dev)
2.2) In the minidlna's Makefile, there should be a couple or so lines that are for static linking (try a search), uncomment those
or
3) Since you're on X86, just download the minidlna static binaries available from their site and save yourself the trouble

Cheers! - Hi LrdShaper,
Thanks for the suggestions, however
>1) Make a softlink of libavutil.so.49 to /usr/lib/i686/cmov/libavutil.so.50.15.1
Tried this, its nagging about incompatible version...

Tried this. I am getting linkage failures, so i stopped trying :-)

Yes, that would save me the trouble, but it would not give me the additional features I am seeking....
Fred - Throw me a copy of the source that includes your changes and I'll try to build it for you. LrdShaper at gmail dot com
It's 12:30AM here and I have a conference call in 30mins so I'll give it a whirl after a good night's sleep - Hi LrdShaper,
Thanks, I will forward you the (complete) sources in a couple of days since I only
today started making changes... as it now is, I can run the minidlna on the debian for test purposes.
The final compilation however should be for readynas....
However, I did already manage to implement the changes needed to enable the (already existing) UUID= setting so now
it is possible to run multiple copies of minidlna.....
As it is, I should be studying like hell, have an exam tomorrow...
I will be able to invest more time once that is behind me...
Fred - Hi LrdShaper,
I have tested my changes on the debian and had contact with the maintainer of minidlna.
From that conversation I hope these changes will be added to the official minidlna source....
Lets wait and see for a while...
Fred - Nice, hopefully you'll get it in a nice .deb package from the official repo :)
