 Description   

When compiling oqgraph in maria-5.2, GCC 4.4.4 reports the following warnings:

Re: Compiler warnings when compiling oqgraph in maria-5.2
The "missing initializer" are already fixed in the current 5.2
In storage/oqgraph/graphcore.cc line 52:
-static const row empty_row =

{ 0 }

;
+static const row empty_row =

{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }

;

I get some of the other errors with gcc 4.3 (Ubuntu 10.04 Lucid).
The warnings appear to be related to the Boost Graph library which we don't directly control, as far as I can see there's nothing we can do about this, directly. Will assign to Antony to review.

Re: Compiler warnings when compiling oqgraph in maria-5.2
For any warnings in the Boost library, please file a bug in the upstream project. Our goal is to have a warning-free MariaDB.
