EDITADO: Al final era una estupidez: Siguiendo el tutorial de Plata en EOL, modifiqué el makefile como indica al final de todo, y, por si las moscas, cambié la libreta de las libNDS. Ahora no puedo compilar y ejecutar en DesMuMe, pero lo ejecuto aparte, compilo y lo cargo manualmente, por lo que este problema no me preocupa. Muchas gracias por vuestras sugerencias, me habéis ayudado a tomar el buen camino ^^.

Buenas, tengo un problema, y es que seguí el videotutorial de amchacon, actualicé PAlib sin problema, incluso hice la comprobación final del vídeo (compilar el Hello World que viene en los ejemplos), sin ningún problema.

Pero ahora, cojo el main.c principal, y sin modificarlo ni nada, lo compilo y me sale esto en la secuencia de errores:

Parece ser que el problema es un tal getIPC, y lo irónico es que antes no me salía nada de esto. ¿Qué puedo hacer?
