Bug #46977	innodb plugin v1.0.4 requres glibc 2.5 or newer

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

(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!

Closing since the plugin is now in the mysql distro and not going to be distributed separately.
