Actualmente estoy intentando realizar una compilación cruzada de un controlador de red con un kernel de Linux antiguo, en la versión 2.6.27.7, pero la compilación falla e imprime:
make[1]: entering directory « /home/johann/Desktop/linux-2.6.27.7 »
Building modules, stage 2.
MODPOST 0 modules
make[1]: leaving directory « /home/johann/Desktop/linux-2.6.27.7 »
El comando que ejecuté para obtener esto se tomó del archivo Léame que se encuentra en las fuentes:
make KSRC=<source> KDIR=<build>
Así es como se ve:
#
# Makefile to build the be2net network driver
#
# find a source path that exists among the possible paths
ver = $(shell uname -r)
paths := /lib/modules/$(ver)/source /lib/modules/$(ver)/build
exists = $(shell [ -e $(path)/include/linux ] && echo $(path))
paths := $(foreach path, $(paths), $(exists))
ifeq (,$(KSRC))
KSRC := $(firstword $(paths))
endif

Respuesta1
Una posible solución es reemplazar obj-$(CONFIG_BE2NET) += be2net.o con obj-m += be2net.o

Necesito saber el nombre del conductor y de dónde lo sacó para que esta respuesta sea exacta.
