Description Colin Williams 2024-03-10 06:05:01 UTC

lmms installed via dnf crashes upon start:

lmms
Notice: could not set realtime priority.
VST sync support disabled in your configuration
Cannot load library /usr/lib64/lmms/libcarlarack.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlapatchbay.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlabase.so: (libcarla_native-plugin.so: cannot open shared object file: No such file or directory)
Segmentation fault (core dumped)

Reproducible: Always

Steps to Reproduce:
1. install lmms via dnf on aarch64 (I used fedora 39 / asahi)
2. launch lmms via lmms command

Actual Results:  

lmms
Notice: could not set realtime priority.
VST sync support disabled in your configuration
Cannot load library /usr/lib64/lmms/libcarlarack.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlapatchbay.so: (libcarlabase.so: cannot open shared object file: No such file or directory)
Cannot load library /usr/lib64/lmms/libcarlabase.so: (libcarla_native-plugin.so: cannot open shared object file: No such file or directory)
Segmentation fault (core dumped)

Expected Results:  
Software should launch not segfault.

Comment 1 David C. Chipman 2024-08-30 12:30:45 UTC

I'm seeing a crash with lmms as well, but not getting so much output. All I'm seeing is this:

Notice: could not set realtime priority.
Segmentation fault (core dumped)

Just ran lmms under gdb, and here's the backtrace I collected:

Comment 2 Aoife Moloney 2024-11-13 12:12:43 UTC

This message is a reminder that Fedora Linux 39 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 39 on 2024-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '39'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 39 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 3 David C. Chipman 2024-11-13 12:39:48 UTC

Problem persists, in Fedora 41

Comment 4 Aoife Moloney 2024-11-28 11:38:13 UTC

Fedora Linux 39 entered end-of-life (EOL) status on 2024-11-26.

Fedora Linux 39 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
