GP2X Help With Building A Kernel Module Fuse

[Pickle]

This is a first for me, so im hoping I can get through some of my problems and learn how to build this kernel module. Its a requirement for another app I want to try on my GP2X.

First I know FUSE isnt in the kernel from GPH or open2x, as both are based on 2.4. If this was Pandora I would be set as this module is included in the 2.6 branch.
So I need to build the module, problem is I need the kernel source code.
Now my first concern is which source do I use, the GPH or open2x?
If I build for one kernel will it not work for the other one?

Right now when I configure the source its detecting my host system's kernel, I think found this to get around it:
CODE
--enable-kernel-module --with-kernel=KERNEL_SOURCE_DIR

Open2x of course . It will work on any filesystem, GPH or Open2x.

Well I want to use open2x, but I didnt want to build a module that woulnt work with the GPH kernel. I guess now I need to get the source code from the svn.

You might be best to use GPH if you only want the module, but I am reasonably sure the Open2x kernel modules are mostly compatible with GPH if you use a 2.95 compiler.

Well I guess I will assume they do. Im using open2x toolchain and kernel source.
Im running into issues with the fuse build.

At first the configure for fuse complained that it couldnt deteremine the version of the open2x kernel. The readme says I need to run 'make prepare', but it appears that option isnt included in the make file for the kernel.

So I decided instead to run the build script for the kernel. First confusing thing is that theres 2 very similar sh scripts. Which one is the latest? Ive run both and have this issue:
CODE
cc1: error: unrecognized command line option "-mapcs-32"

I also went back to try to compile fuse and now it can detect the kernel version, but I get a compilation error now:
CODE

/opt/projects/linux-open2x-2.4.26_FW2-3/include/asm/semaphore.h: In function queue_request':
/opt/projects/linux-open2x-2.4.26_FW2-3/include/asm/semaphore.h:110: error: unknown register name 'lr' in 'asm'


Can you help anymore with this Orkie?
Update: I just realized im using the app toolchain and not the kernel toolchain. I will download the kernel based one and report back

 

[Orkie]

Looks like you are using gcc4.1. You want to be using 2.95 if you want a module compatible with the GPH firmware (and anything above 3.4 won't work with any 2.4 kernel, and only 2.95 works with the GPH source).

Yeah I caught the gcc problem a little before you posted, but with your suggestion im downloading both 2.95 and 3.4.4.

Ok i have gcc 2.95 and get the following results:

Trying to build the open2x kernel using the 2.95 script. I didnt make any changes in the config menu that comes up.

Did you give up on me Orkie

 

[Orkie]

No, I have just been busy . I'll have a proper look at that post later.
