[sane-devel] sane SCSI 32bit emulation on 64bit

[Dieter Jurzitza]

Hi Mr. Kuhlmann,
I was the one to bring up the issue with the SPARC workaround, the sane folks 
helped me a lot to do the testing and find out that using the "old" interface 
made everything work.

And, as a matter of fact, everything on SPARC64 is compiled 32 bit in the user 
world. Only the kernel is 64Bit. Therefore you might want try to compile sane 
32 bit using the old interface - this works on SPARC64, so it might work on 
other 64Bit platforms, too. 

On SPARC64 there is an autodetection for this, but as it has been suggested by 
Mr. Deuring - you could enable it "hard" by default.

The only thing I cannot tell - well, on SPARC64 you have to say sparc32 make 
to compile 32Bit - I do not know how to achieve this on 64Bit X86 
architecture. 
Good luck,

take care
