MySQL Bugs: #46977: innodb plugin v1.0.4 requres glibc 2.5 or newer

Bug #46977	innodb plugin v1.0.4 requres glibc 2.5 or newer
Submitted:	28 Aug 17:12	Modified:	2 Sep 12:39
Reporter:	Matthew Lord
Status:	In progress
Category:	Server: InnoDB Plugin	Severity:	S2 (Serious)
Version:	1.0.4	OS:	Linux
Assigned to:	Vasil Dimov	Target Version:
Tags:	glibc

Description:
I've only seen this on x86_64 platforms so far but I suspect it affects x86 as well.

If you're glibc version is less than 2.5 you'll encounter one of two errors:
1) ha_innodb.so' (errno: 0 requires glibc 2.5 or later dynamic linker)
2) ld actually tries to link in the library and mysqld dies with a signal 8

How to repeat:
try to use mysql-5.1.37-linux-x86_64-glibc23.tar.gz with
innodb_plugin-1.0.4-linux-x86_64-glibc23.tar.gz 

Suggested fix:
Correct the build process so that only glibc 2.3 or newer is needed.

Hello,

I am able to reproduce this:

ha_innodb.so must be linked with --hash-style=both in order to work on libc 2.3 systems.
Originally we compile it on libc 2.5 system. Binary compiled without --hash-style=both
shows this in objdump -h:

Idx Name          Size      VMA               LMA               File off  Algn
  0 .gnu.hash     000001ec  0000000000000158  0000000000000158  00000158  2**3
                  CONTENTS, ALLOC, LOAD, READONLY, DATA
  1 .dynsym       000018c0  0000000000000348  0000000000000348  00000348  2**3
                  CONTENTS, ALLOC, LOAD, READONLY, DATA

Binary compiled with --has-style=both shows:

(Thanks, Sunny and Marko!)

For 1.0.4 either compile your own ha_innodb.so from source or use the official ones on
libc >=2.5 systems. For 1.0.5 we will fix this problem.

Thank you!

I am a little confused by this bug, I am trying to install plugin version 1.0.4 on Mysql
5.1.37 on Fedora 11. I get this error, but the glibc version on my system is 2.10 so why
am I having this problem? Or is it the fact that the plugin binary was compiled with 2.3
that is causing me to have this issue? Was really looking forwards to trying out this
plugin...

Sorry for the spam, just to let you know that I used the RHEL5 binary and it starts up
without any errors. This is on a 64-bit system FYI.

JF Prieur,

Right, the problem occurs if the plugin is used on a too-old libc, not too new :)

Thanks!
