I receive the massage “/usr/lib64/ladspa/caps.so: undefined symbol: _ZN3DSP10Polynomial5one53Ef” every time I try to use the plugin caps.so from ladspa. It happens on all programs I tried, Ardour and Audacity.
All the involved packages are x86_64 and I do not have the 32 bits version installed.
I used the 15.3 version caps.so file, substituted the file directly and now it works like a charm.
Why the 15.4 version of the package ladspa-caps is not working?
