failed aggregating - error loading libnuma.so.1

[step-]

I installed net.downloadhelper.coapp-1.1.0-1_amd64.tar.gz. coapp's ffmpeg fails with the message below. NUMA isn't available for my Linux/GNU box. Is libnuma a strict requirement for coapp to work? Thanks.

Failed aggregating ...

/usr/local/net.downloadhelper.coapp-1.1.0/converter/build/linux/64/ffmpeg: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

Apparently libnuma is to be used as a dependency of the coapp or one of the libs. Some users reported it worked after installing libnuma on the system. If you use Fedora, maybe from there: [https://www.rpmfind.net/linux/rpm2html/search.php?query=libnuma.so.1()(64bit)](https://www.rpmfind.net/linux/rpm2html/search.php?query=libnuma.so.1()(64bit)) ?

Yes, libnuma is one of the dependencies. I compiled in installed it and now coapp works. But it's a rather unusual dependency, given that NUMA is a distributed memory system - high-end hardware stuff as I understand. My thinking is that either coapp or ffmpeg require libnuma. If it's ffmpeg, and it's a compile option, I suggest to turn it off and recompile ffmpeg. If it's coapp requiring libnuma, then what for? Thanks.

I'm pretty sure it's not the coapp itself. It's either ffmpeg or one of the libraries that go with it. Since it's open-source and totally free on Linux, i hope someone will take the time to fix it before this issue comes at the top of the priority list. A better solution than to remove the libnuma requirement (which might not be possible anyway), is to compile it as part of the package, like this is the case for libz.

Exactly from which binary package did you extract the ffmpeg that's included in https://github.com/mi-g/vdhcoapp/releases/download/v1.1.1/net.downloadhelper.coapp-1.1.1-1_amd64.tar.gz?

[mi-g]

The ffmpeg programs (ffmpeg, ffprobe and ffplay) are not extracted from a binary package but compiled from scratch, along with a bunch of libraries. Look at the converter sub-directory, there are 2 scripts:

• get-source.sh: connect to various servers and get source code
• build-apps.sh: compile everything (on Linux, compile for Linux and Windows, on Mac, compile for Mac)

I have the same problem. The file suggested to download net.downloadhelper.coapp-1.1.3-1_amd64.tar.gz doesn't contain any compiler option. It has only the binaries.

I workaround pointing to the OS ffmpeg* executables:

mv ffmpeg ffmpeg.netdl
mv ffplay ffplay.netdl
mv ffprobe ffprobe.netdl
ln -s /usr/bin/ffmpeg ; ln -s /usr/bin/ffplay ; ln -s /usr/bin/ffprobe 

But that dependency should be pulled in or removed.

vdhcoapp 1.2.1 includes its own build of library libnuma in case it is not available by default on the target linux distribution.
