Public bug reported: Pd-0.50.2-3 (as shipped with focal) is unable to load the external objects (plugins) shipped in the "puredata-extra" package (which is built from the same source package as "puredata" itself) due to a problem with some symbols that should be provided by libm.
The missing symbols are `__exp_finite`, `__log_finite`, `__logf_finite` and `__pow_finite`. The affected externals are: - bonk~ - choice - fiddle~ - sigmund~ The problem appears to come from a change in the symbols when upgrading from glibc-2.30 to glibc-2.31 (e.g. see https://sourceware.org/pipermail/libc-alpha/2020-May/113773.html) [Test Plan] a quick way to check whether the objects can be loaded is by running this script (after installing the "puredata-extra" package): ~~~ find /usr/lib/puredata/extra/*/ -name "*-help.pd" -exec pd -nrt -nogui -send "pd quit" {} ";" ~~~ i've attached the output of such a test run (note the lines starting with "error:") ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: puredata-extra 0.50.2-3 ProcVersionSignature: Ubuntu 5.4.0-80.90-generic 5.4.124 Uname: Linux 5.4.0-80-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 CasperMD5CheckResult: skip Date: Mon Aug 9 11:23:35 2021 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: puredata UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: puredata (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal uec-images ** Attachment added: "test run that shows missing symbols" https://bugs.launchpad.net/bugs/1939293/+attachment/5516803/+files/pd-0.50.2-3.log -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to puredata in Ubuntu.
