Compiling at76c503a berlios wlan on Sparc

I've downloaded the berlios wlan driver to work with my linksys WUSB11 wireless card. This USB card works fine under RH9 (386 architecture) but only using the berlios driver. I tried the other atmel drivers and they didn't work. I have been given a nice Ultra 10 and would like to use the WUSB11 with it.

http://download.berlios.de/at76c503a/at76c503-0.11.tar.gz

I downloaded and then tried to compile it. During compilation it complained about architecture so I modified CFLAGS by adding -mcpu=ultrasparc. This helped the compile to complete without errors, though there were a large number of worrisome warnings.

Next I type in make install and it fails :

Any help with this would be appreciated.

Remember you have to pass -m64 as well to compile your modules as 64-bit. Look at the output of 'make modules' from your kernel to get a good idea of flags you will need.

The files with i386 in the name also could be a problem, you might want to make sure there is nothing like assemblly code, or anything else i386 specific in those files.

Ajdusting the makefile to use sparc64-linux-gcc as the compiler made those drivers build for me here. However I don't have one of those cards so I can't test to see if it works.

Hey,

I should have mentioned that I'm new to the Sparc arena and haven't coded in C in a number of years.

I modified my makefile to use the sparc64-linux-gcc compiler. That gave errors. I also ran make modules from from usr/src/linux and picked up the compiler flags and replaced the CFLAGS and CPPFLAGS with them. Still got errors.

Would you mind posting your modified Makefile.

Thanks,
Charles

Well I upgraded my kernel from 2.4.24 to 2.4.25 and it compiled and installed just fine. Problem solved
