Matching subscriptions: Ubuntu Studio Bugs https://bugs.launchpad.net/bugs/1939293 Title: unable to load externals: undefined symbol "__pow_finite" and similar Status in puredata package in Ubuntu: New Bug description: [Impact] 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) A simple rebuild of the package seems to fix the problem. To trigger a rebuild I've added a debdiff that bumps the version number to "0.50.2-3build1~ubuntu20.04.1" (i hope this is the correct version scheme for such an upload). [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 (failing) test run (note the lines starting with "error:") [Where problems could occur] The rebuild apparently fixes the problem, although a more correct fix would probably be to add "-lm" to the linker-flags when building the plugins. (This is what upstream did for the Pd-0.51 release). In order to keep the impact of my patch minimal, i have chosen to just trigger a rebuild.
