 Posted: Fri Dec 09, 2005 2:03 am Post subject: Compile error of last version |
 |
|
I'm trying to compile mysql normal on a Slackware 10.2.
All seems to work fine in the first part of compilation,
but at the end I receive this error message:
===============================================
In file included from /usr/include/asm/atomic.h:6,

I'm using a kernel 2.6.14.3. Any suggestion?
Thanx!

Strange, that looks like a bug in a header file. What configure options did you use?

This one:
CFLAGS="-O2 -march=i486 -mcpu=i686" CXX=gcc CXXFLAGS="-O2 -march=i486
-mcpu=i686" ./configure \
--prefix=/usr \

I made a try... Compilation not only with kernel 2.4,
but with kernel 2.6.13.4 too works fine.
So I really think it's a trouble with 2.6.14.3 headers...
Do u think I can write to kernel manteiners?
Thanx

I communicate it to bugzilla. The kernel team replied:
======================================First of all, the kernel headers aren't directly usable for userspace, your
distribution should ship sane headers.
Additionally, last I checked MySQL abused atomic.h in a way it was never meant
to be used (for using the inline functions in userspace).
======================================
I compiled from myself the headers for the most recent kernel.
With 2.6.13 mysql compilation worls fine, with 2.6.14 no.
Please, consider if the problem is not of mysql itself...
Thanx

The Red Hat distribution of mysql ran into this problem quite some time
ago: the "atomic add/sub" assembly code doesn't work on any of RH's
64-bit platforms. Fortunately there is a configure-driven option to not
use that code. We fix it by hacking configure.in (see attached patch,
which presumes that you run autoconf afterwards) but I suppose you could
also do it by modifying configure's output files. The patch was
generated against 4.1.x, as you can see, but it still applies to 5.0.x.
regards, tom lane
The idea of userland using <asm/atomic.h> has our kernel hackers all bent
out of shape, so don't do it. Suppressing this has another benefit too,
which is we avoid the 4-vs-8-byte problem in BDB that formerly required
mysql-threads.patch.

Could you please give me the related Bugzilla ID for reference?

It's a MySQL problem, related to the detection of atomic operations in
"configure".

Thanks! Could you please alert us about such issues via our bug database at
http://bugs.mysql.com/ in the future? That should make sure you don't have to
maintain such fixes by yourself forever and we don't have to trawl through all
vendors' SRPMs for useful patches :)

Agreed, this is ugly. It seems like this particular issue was reported in
our Bugs DB already:
http://bugs.mysql.com/bug.php?id=13621
http://bugs.mysql.com/bug.php?id=15244
I will nudge our devs about this one again. Thanks for the reminder!

Here's something you might find interesting: latest gcc breaks mysql
in at least one place
