Subject: lcd4linux: FTBFS: undefined reference to `rdtscl'

Date: Tue, 7 Aug 2007 00:57:06 +0200

Package: lcd4linux

Hi,

During a rebuild of all packages in sid, your package failed to build on i386.

Hi Reinhard,

according to:
| kibi@becky:~/lcd4linux-0.10.1~rc2$ rgrep rdtscl /usr/include 
| /usr/include/asm-x86_64/msr.h:#define rdtscl(low) \
| /usr/include/asm-x86_64/msr.h:#define rdtscll(val) do { \

I guess that you want either check for the presence of asm-x86_64/msr.h
(easy way) or keep on using asm/msr.h and add a code snippet to find out
whether rdtscl() is really available.

Cheers,

I took a look at this; here is my analysis:

lcd4linux' configure checks for the presence of /usr/include/asm/msr.h,
which is on your buildd. that file contains on my system this:

#ifndef __ASM_STUB_MSR_H
#define __ASM_STUB_MSR_H
# if defined __x86_64__
#  include <asm-x86_64/msr.h>
# elif defined __i386__
#  include <asm-i386/msr.h>
# else
#  warning This machine appears to be neither x86_64 nor i386.
# endif

I can only conclude that you build defines the macro '__x86_64__'
confuses lcd4linux. Which is of course an important bug, but in no way
release critical, IMO.

Do you run sbuild with 'linux32' prefixed, so that tools like 'uname -m'
don't report x86_64?

Yes, I do.

I tried to reproduce this locally (x86 laptop), and it fails to build in
the same way. So re-bumping severity.

Not a real hint, but this has been reported in debian as well:

rdtscl is not defined anywhere except in /usr/include/asm-x86_64/msr.h.

I would have expected it to be defined on i386 when asm/msr.h is included.

rdtscl was removed as linux does not longer assume that it is able to
ask the TSC themself. Also it is unsafe to access the TSC from
userspace. I doubt that it is a bug at all in the kernel. Userspace
should use gettimeofday.

If you really think this is wrong, ask upstream yourself.

I don't consider this a bug. This macros defined a cpu-interface, not a
userspace-kernel interface. Also the tsc is not reliable usable by
userspace.
