Hi,

I'm actually writing a series of scripts using checkinstall.

Q: how do I find out which i?86 I am on? My scripts are supposed to run on
different architectures, and I give the result of a source compilation over
to checkinstall, and I'd like to inform the --pkgrelease field with a
variable that is i686 on i686 systems, i486 on i486, and so on.

Any suggestions?

Everything works -- if you let it.

maybe read /proc/cpuinfo ?

idunno but i'm guessing 'cpu family' is what you want.
a quick check here shows an Athlon and a P3 as '6' and
an ancient pentium 166 as '5'.

I think you'll find that doesn't hold for all chips. I have one computer
with a VIA C3 which reports 686 under Slack 10.0 and hangs on some 686
instructions. It works fine after I set flags to i586. And I have another
AMD 64 bit cpu that reports x86_64 running Slamd64 10.2, which is a bit
confusing. (Why not 686_64 or higher...?)

Have you done some benchmarking to discover how much difference
compiling applications for different i?86 makes?

Grant.

Try 'uname -m

Hope this helps

Unfortunately that won't easily provide what I believe is being sought,
in all cases. On a system I have here, running Slackware-10.2:

: calliope[syl] ~; cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 47
model name : AMD Athlon(tm) 64 Processor 3500+
...
: calliope[syl] ~; uname -m
i686


I'm not sure where the uname(2) system call gets the machine type
information, but I suspect it may be compiled into either the kernel
(though that _has_ been customized with the proper processor
information), or the C library, for example.
