x86_64 builds

x86_64 builds

[Florian Bomers]

Hi,

when trying to compile ALSA drivers 1.0.5a on SLES 8.1 with 
kernel 2.4.19, the configure script always detected "k8" so 
gcc was called with "-march=athlon". This resulted in module 
binding problems, and I could not find a way to explicitly 
compile for x86_64. I hacked configure.in so the check

     #elif defined(CONFIG_X86_64)
         fprintf(file, "x86_64");

comes right at the beginning of the long list of #elif's. On 
AMD64, both CONFIG_MK8 and CONFIG_X86_64 are defined, so 
without the hack the configure script would always assume k8.

I think it makes sense to modify configure.in so that it 
compiles for 64-bit by default, or, at least, add a 
configure parameter to explicitly choose 64-bit.

Florian

Right.  I'll fix this on CVS.


thanks,
