An error occurred while adding fusion compilation to the kernel: scripts/makefile. Build: 233: The target "Drivers/Char/fusion" does not match the target mode.

1. Copy the fusion folder to the driver/Char directory of the kernel;

2. Configure driver/Char/makefile:

# Makefile for the kernel character device drivers.### This file contains the font map for the default (hardware) font#FONTMAPFILE = cp437.uniobj-y    += mem.o random.o tty_io.o n_tty.o tty_ioctl.o tty_ldisc.o tty_buffer.o tty_port.oobj-$(CONFIG_FUSION_DEVICE)     += fusion

3. Configure driver/Char/kconfig:

source "drivers/s390/char/Kconfig"source "drivers/char/fusion/Kconfig"endmenu

4. Modify Drivers/Char/fusion/makefile as follows:
[Sdk1.4 @ 88 embeddedlinux] $ Vim Drivers/Char/fusion/makefile

obj-$(CONFIG_FUSION_DEVICE) += fusion.ofusion-y := call.o entries.o fifo.o fusiondev.o fusionee.o list.o property.o reactor.o ref.o skirmish.o shmpool.o

5. Modify Drivers/Char/fusion/kconfig as follows:

[sdk1.4@88 EmbeddedLinux]$ vim drivers/char/fusion/Kconfigconfig FUSION_DEVICE        tristate "Fusion Kernel Device"        ---help---          Fusion is the IPC API used by DirectFB and FusionSound.

Compilation error:

Scripts/makefile. Build: 233: The target "Drivers/Char/fusion" does not match the target mode.

Do you want to understand?

Check carefully. Problems found:

#FONTMAPFILE = cp437.uniobj-y    += mem.o random.o tty_io.o n_tty.o tty_ioctl.o tty_ldisc.o tty_buffer.o tty_port.oobj-$(CONFIG_FUSION_DEVICE)     += fusion/obj-$(CONFIG_LEGACY_PTYS)       += pty.o

Take a closer look.

 

The reason is that fusion is a folder.
