[debian-mysql] Bug#641375: Bug#641375: Missing includes to build MySQL storage engine plugins

[Xypron]

Hello Clint,

thank you for the reference to package handlersocket.

Just as a matter of notice. It is not building in-tree, but uses a 
parameter for the configure script to indicate the location of the 
necessary includes, which have to be extracted from the source package 
before.

Best regards
