I'm using pd-vanilla (0.50.2-3) on ubuntu studio 20.04
It was installed by default (so I didn't build it myself).
When I try to create a sigmund~ (or even fidle~ or bonk~) object, I have this error:
/usr/lib/puredata/extra/sigmund~/sigmund~.pd_linux: /usr/lib/puredata/extra/sigmund~/sigmund~.pd_linux: undefined symbol: __pow_finite /usr/lib/puredata/tcl/../extra/sigmund~/sigmund~.pd_linux: /usr/lib/puredata/tcl/../extra/sigmund~/sigmund~.pd_linux: undefined symbol: __pow_finite sigmund~ ... couldn't create
There is a file /usr/lib/puredata/extra/sigmund~/sigmund~.pd_linux
I red about an almost same issue here https://github.com/pure-data/pure-data/issues/975 but didn't find a solution I may understand.
Some says this problem is common since 20.04 but didn't find any other topic about that searching on google.
Would someone have any clue?
EDIT: I found out that on an other boot I have (MXLinux), installing puredata (which install by default in 0.43 (or 49? not sure...)) gave me sigmund~ working fine. so I tried to copy the sigmund~.pd_linux file from this build to the one on my other boot (backuping the original one of course). But it didn't work.
Maybe I could try to install an older version of PD on my ubuntu studio (I need to use it on this one, because I didn't find how to build processing for MXLinux, which is essential to my usage). But I don't know how to proceed (where to found the package, plus I'm really not good in building package successfully ...)
