happycoders-libdbg-dev binary package in Ubuntu Bionic ppc64el

 It provides various constraint checking utilities together with an
 integrated error logging facility. These utilities are flexible and
 customisable. They can be enabled and disabled at runtime, and in release
 builds, dbg library use can be compiled away to nothing.
 .
 Rich debugging can only be implemented in large code bases from the outset,
 it is hard to retrofit full defensive programming techniques onto existant
 code. For this reason it is good practice to use a library like dbg when
 you start a new project. By using dbg extensively you will find bugs
 quicker, and prevent more insideous problems rearing their head later in
 the project's life.
 .
 This package contains the symlinks, headers, and object files needed to
 compile and link programs which use libdbg.
