Re: StreamDevice error involving PCRE library in Debian Trixie

Hej Jörn,

shooting into the blue:
Do you have the calc mdoulein your tree ?
Is it configured/needed in configure/RELEASE ?
Or any other file under configure/ ?

Or somewhere in one of the Makefile(s)?

Where you may be able to comment it out ?

Just guessing.
