dejo adjuntado los codigos y aca les dejo el link del pryecto original!

Tu problema se resuelve reemplazando static por const

const unsigned char PROGMEM pr[] = {

Luego de arreglar tu problema inicial, salta este otro

C:/Users/Ricardo/Downloads/Foro arduino/Borrar/glcdfont.c:9:23: error: variable 'font' must be const in order to be put into read-only section by means of '__attribute__((progmem))'

 static unsigned char  font[] PROGMEM = {

De nuevo lo resuelves asi, nada de static, debe ser const

const unsigned char  font[] PROGMEM = {

y hay mas errores.

C:/Users/Ricardo/Downloads/Foro arduino/Borrar/glcdfont.c:9:22: error: 'font' has a previous declaration as 'const unsigned char font [1275]'
 const unsigned char  font[] PROGMEM = {

ahora me sale esto

Exacto... ubica el error porque esta aparentemente repetido.
o bien saca el archivo bigfont.c para probar porque parece que ya lo usan en adafruit_PCD8544.cpp
