3.Making driver module

(1)Copying the driver source file

Copy the driver source file to the directory which includes PCMCIA Client Driver source.

(The directory normally means pcmcia-cs clients directory)

If there is the extracted driver source file in the directory /root/cb32, type the command as written below.

# cd /usr/src/linux-2-2.12/pcmcia-cs-3.0.14/clients

# cp /root/cb32/src/* .

# cp /root/cb32/lib/* .

The cb32i850.c , cb32i850.h , cb32scsi.c , cb32scsi.h , load_fw.o files will be copied.

(2)Editing Makefile

Add the seven lines below to Makefile in the clients directory to compile cb32_cb.

cb32_cb.o : cb32i850.c cb32scsi.c cb32i850.h cb32scsi.h

$(CC) -MD -c $(XFLAGS) $(CPPFLAGS) I$(LINUX) cb32i850.c -o cb32i850.o

@mkdir -p .depfiles ; mv cb32i850.d.depfiles

$(CC) -MD -c $(XFLAGS) $(CPPFLAGS) I$(LINUX) cb32scsi.c -o cb32scsi.o

@mkdir -p .depfiles ; mv cb32scsi.d.depfiles

$(LD) r o $@ cb32i850.o cb32scsi.o load_fw.o

rm -f cb32i850.o cb32scsi.o ; chmod x $@

Refer to the Makefile in the [samples] folder.

(3)Editing proc_fs.h

Go to the include/linux directory.

# cd /usr/src/linux-2.2.12/include/linux

Edit proc_fs.h to add [PROC_SCSI_CB32, ] right after [PROC_SCSI_INIA100, ] line.

Refer to the proc_fs.h in the [samples] folder.

If you can find proc_fs.h in the directory /usr/include/linux, edit it in the same way.

(4)Compiling cb32_cb

Compile cb32_cb with make command.

# make cb32_cb.o

Caution: If you get the error message saying [Makefile:8: ../config.mk:No such file or directory make: ***

No rule to make target ‘../conifg.mk’. Stop], Move up one directory and execute [make config].

You will get config.mk. Then move back to the clients directory and execute make command.

# cd ..

# make config

# cd clients
