make and driver installation

[keithclark]

I have a serial to usb adaptor and it came with linux drivers but I have no idea how to use them.

When I run make I get the following messages:

Where did you get the Makefile and the Rules.make from? Seems a bit overcomplicated for compiling a single kernel device driver.

Plus this statement is not portable:


INCLUDEUSBSER := $(shell echo "/usr/src/linux-`uname -r`/drivers/usb/serial/")

It probably should be:


INCLUDEUSBSER := $(shell echo "/lib/modules/`uname -r`/build/drivers/usb/serial/")

Aside from that, the only other issue I can think of is that maybe you do not have the kernel development files installed; but this seems highly unlikely.

[keithclark]

I got these files straight from the supplier.

I changed as recommended and still a ton of errors.

[dwhitney67]

Within your working directory (i.e. where the files the vendor supplied you), what files do you have?

[keithclark]

ftdi_sio.c
ftdi_sio.h
Makefile
Rules.make

[dwhitney67]

Create a backup of your existing Makefile, and replace with this one:



SRCS = ftdi_sio.c
OBJS = $(SRCS:.c=.o)

obj-m += $(OBJS)

CFLAGS += -I./


all:
$(MAKE) -C /lib/modules/`uname -r`/build M=$(PWD) modules

clean:
$(MAKE) -C /lib/modules/`uname -r`/build M=$(PWD) clean
$(RM) Module.markers modules.order

This Makefile will not install anything, and in fact I do not even know if it will work. But give it a shot. If all works well, there should be an ftdi_sio.ko (kernel object) file in your present working directory.

P.S. Note that with Makefiles, the indented statements are done with a single tab, and not spaces.

i would like to know the solution to this as well. I am encountering a similar problem while trying to install AODV routing protocol for the Ubuntu kernel. I take it this issue has something to do with the kernel and not the makefile since the software I am trying to install is completely different.

i would like to know the solution to this as well. I am encountering a similar problem while trying to install AODV routing protocol for the Ubuntu kernel. I take it this issue has something to do with the kernel and not the makefile since the software I am trying to install is completely different.

As I pointed out in one of my earlier posts, the linux header files are not always installed in /usr/src. It can be installed in a different location... or in some cases, not at all (but this is rare). Thus the Makefile may not be portable.

The defacto location to look for the source code is in /lib/modules/`uname -r`/build.

On an Ubuntu system, the linux header files are in /usr/src/linux-headers-`uname -r`, but that is the choice of Ubuntu; it may not be applicable to another distro.

As for the issues you are having, I cannot comment on them without seeing the errors as generated by the make process.

P.S. Woohoo! I have now made 2500 posts!
