just tested it here, 0.50.2-3 shows the bug, and the focal proposed 0.50.2-3ubuntu0.1 works fine. And thanks Iohannes, i saw some new users with the problem, and to solve it we needed to teach people building puredata from source, which is easy, but for newcomers isn't as easy as just downloading the package! thank you!

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: Fix Released Status in puredata source package in Focal: Fix Committed 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.
