Description:
Linking of mysqld fails with lots of dublicate symbol warnings
followed by one error

  ld: 0711-317 ERROR: Undefined symbol: 
  backup::__vftQ3_6backup10Image_info6TablesQ2_6backup10Table_list

How to repeat:
Compile using VisualAge 6 on AIX 5.2
[15 Sep 2008 22:25] Chuck Bell 
The Visual Age compiler was replaced with Xlc on AIX.

However, there are three issues with compiling backup on AIX:

1) The line terminator on method definitions causes a compiler error:

int my_method()
{
}; <---- Shame! Remove this.

2) There are C++ comments in .c files.

// this is bad

should be

/* this is better */

3) There are some namespace issues in backup_info.cc.

Patch is being tested. Solution forthcoming.

Patch complies. All tests pass with patch except backup_timeout.

The backup_wait_timeout variable is not being set when the command 'SET backup_wait_timeout=X' is issued. Investigating.
[16 Sep 2008 15:52] Chuck Bell 
The failure for the backup_timeout error is due to the value specified on the command not reaching the constructor for the sys_var class. A new bug will be opened to address this issue.

      BUG#29643 : Backup: Link failure of executable mysqld, symbol in backup not found 
      
      The backup code contains constructs that are not compatible with the Xlc compiler
      (formerly VisualAge) on AIX.
      
      The errors include:
      * C++ comments in a .c file
      * Namespace issues.
      * Extra ; after method definition
