No funciona en Debian y Ubuntus actualizados (versión PC al menos)

[cpcbegin]

Después de actualizar los sistemas he ejecutado CapriceRPI y sale el siguiente error:

capriceRPI-notpi: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

He intentado recompilar pero me sale el siguiente error:

El problema lo he reproducido en Debian 9 32 bits. en Ubuntu Mate 18.04 64 bits y Ubuntu Mate 16.04 64 bits.

El mismo error se reproduce al probarlo en Raspbian Buster en la Raspberry Pi 4.

Mi Raspberry de desarrollo esta estancada en Raspbian Wheezy (Si algo funciona, no lo toques), a ver si puedo actualizarla a Buster y lo miro.

Es algo que tenia pendiente de hace mucho, ir limpiando librerias obsoletas y muchos warnings originales del codigo que cualquier dia no sean admitidos por el compilador (Vamos, que hay tela para mirar xD )

Miy dev Raspberry is running Wheezy (You now, if something works, don't touch it), I will try to update to Buster and have a look.

I have clear that I also have to check some old libraries and lot of woarnings from the original code that will not be allowed someday by compilers (lot of work xD )
