OmAudiolib error in Ubuntu 19.10

OpenMusic
#1

Hello,

After a clean install of ubuntu 19.10 I got the following error trying OM 6.16

ERROR: Illegal instruction(4) [code 0] at 7FAA29CE4E10
Unknown foreign code in module “/home/rrrrrrrrr/Downloads/OM_6.16/resources/lib/linux/OMAudioLib.so” [ #x7FAA29BCE000 ]

Also I’m not able to compile it from git: missing alsa and libcurl packages.

Please, provide a solution. Thanks in advance.

best regards,

Hi rc. Please provide more info, esp. which release of OM, as well as the output of:

$ lsb_release -a

Also I’m not able to compile it from git: missing alsa and libcurl packages.

Take it you’re referring to OMAudioLib. That would be expected, you’ll need the dev-versions of the deps to compile OMAudioLib.so yourself.

Yes, I tried to compile omaudiolib.

which of these should I install for libcurl?

libcurl4 libcurl4-openssl-dev libcurlpp-dev
libcurl4-doc libcurl-ocaml

and for alsa?

alsa-base alsaplayer-daemon alsaplayer-xosd
alsa-firmware-loaders alsaplayer-gtk alsa-source
alsamixergui alsaplayer-jack alsa-tools
alsa-oss alsaplayer-nas alsa-tools-gui
alsaplayer-alsa alsaplayer-oss alsa-utils

Dear RC,

First of all, why do you install an rpm under Ubuntu. You should use instead the .deb installer. try this before compiling omaudiolib

best

PS: For the dependencies to compile omaudiolib, i believe you will need:
libcurl4-gnutls-dev and libasound2.

Sorry, copy paste error. Before, I downloaded the [OM_6.16.tar.bz2]
(https://github.com/openmusic-project/openmusic/releases/download/v6.16/OM_6.16.tar.bz2)

Now, after installing the suggested .deb I got this error:

ERROR: Illegal instruction(4) [code 0] at 7FEC42560E10

Ok ,

this seems to be the same illegal instruction error due to your processor (is it a dual , ie. an old 64bit processor ?).

Now please do try to substitute this lib:
/usr/share/openmusic/resources/lib/linux/OMAudioLib.so

with the one i am attaching to see if it works (in the zipped archive)OMAudioLib.so.zip (1.2 MB) .
If not, will give you further instructions
