Hey jay,
Ok. Several things. First, I imagine that your original problem was that
whatever you have in the name field needs to match the name you give to drizzle
plugin declare. I recommend going back to load_by_default=yes and trying to
match the names.
Names were/are identical.
Second, a don't believe that sources is comma separated. I think it's space
separated. Third, headers don't go in sources, they go in headers. (Iirc... I
am sitting on bart right at this moment.)
OK, fixed.
Fourth, LIBPROTO is most likely empty, since that is not a variable we set
anywhere. LTLIBPROTOBUF is likely the var you want. You also have mismatched (
and }.
Thanks, fixed.
I'm not 100% sure plugin-load works at all right now... it's on my short list
of things to fix/rework. But if do want to give it a spin, you'd need to
provide it with an .so file. A .la file is a libtool artifact that contains
meta info pointing to the libs.
Yes, I would have provided an .so, but could not find where one was
generated anywhere...
Finally, don't forget to re-run autorun.sh after you modify plugin.ini.
K.
It seems the problem was the load_by_default= no and the libraries
having a typo. Building fine nwo.
Thanks!

Hi Monty,
cc'ing the list since the answers may be helpful for folks trying to
develop plugins...
So, I have completed coding the new default serial event log (binlog).
I am trying to create the test suite properly and am running into some
issues -- likely stemming from my not understanding the autotools foo
that is happening for plugins.
This is what I have in /plugin/serial_event_log/plugin.ini:
[plugin]
name=serial_event_log
title=Serial Event Log
description=Default Serial Event Log for Drizzle
load_by_default=yes
sources=serial_event_log.cc,serial_event_log.h
libadd=$(LIBPROTO}
When compiling with the above setup, I get a linker error when in the
drizzled/ directory:
sql_plugin.o:(.data+0x30): undefined reference to
`builtin_serial_event_log_plugin'
If I remove the line:
load_by_default=yes
from plugin.ini, then compilation works properly.
However, when I tried setting up the master.opt file in the new
serial_event_log test suite, I put the following:
--plugin-dir=/home/jpipes/repos/drizzle/replication/plugin/.libs
--plugin_load=libserial_event_log_plugin.la
And I get the following:
Can't open shared library
'/home/jpipes/repos/drizzle/replication/plugin/.libs/libserial_event_log_plugin.la'
(errno: 22
/home/jpipes/repos/drizzle/replication/plugin/.libs/libserial_event_log_plugin.la:
invalid ELF header)
in the server error log.
I've tried various versions of plugin-dir, plugin_load, but can't seem
to get the darn library to load.
Could you assist?
Thanks!
Jay
p.s. This is also a gentle reminder for some documentation on how to do
this stuff on the wiki ;)
