Re: Build Error - gcc must provide the <cpuid.h> header

[Sreyan Chakravarty <sreyan dot mailing at gmail dot com>]

Guess you are right. Something is wrong with my toolchain. The test
program you gave did not compile.

But when I did a
find /usr/ -name cpuid.h

/usr/src/linux-headers-2.6.24-32-generic/include/config/x86/cpuid.h

I managed to find the above file. What bothers me is that, it was
found under x86 while I am clearly trying to compile for x86_64.

Thanks for shedding light on why my configuration process is failing.

Do you have any ideas why this might be happening ?
