I put the patches for Mac OS X to build 3.23.27-beta at
The patches are minor (an extra #define to get MCL_CURRENT, used in sql/mysqld.cc as an
argument to mlockall(); and fixes to the pthread #define's).
I also put a binary built version for Mac OS X at
Would it be possible for someone to merge the patch into the source code?
And ideally put the binary on your web site?
