Compilation on raspberrypi

[jorisc90]

Hi dorimanx,

After commit cda06f6e73005d0a06395fbb1a6ca022fac421ec, the compilation on my raspberrypi fails with the error

Any ideas on this pointer type? a >= that is too complicated? Strange. Kind regards,

[dorimanx]

i see you try to build it as any kernel module using your linux build as compiler.

but you didnt read any INFO about this driver correct???

it's for ANDROID and must be compiled with ARM compiler

any way it's missing define that triggered for your installed kernel 3.12.22 that dont have or updated functions that module need to build for 3.12.y

Please read info, and check what functions you do have in your kernel, and set correct defines in exfat_core.c exfat_super.c

The raspberry pi is an ARM device (http://www.raspberrypi.org/), that is why I am compiling it using the normal linux build; thus I did read the information about the driver. Thanks for the comment, I got it working again. No more fuse eating up my CPU :)

@jorisc90 Can you explain step-by-step how you installed exfat-nofuse on RPi? I don't achieve to do it...

[jorisc90]

Hi @josephernest - It's been some time since I did this, no longer have the particular RasPi device in use.

If I recall correctly I followed the readme, issuing make and then sudo make install to perform the installation on Raspbian Linux (which back then had the 3.12.22 kernel version).

Sorry I can't be of further help here...
