Comments - Installing OQGRAPH

I'm getting an error 2 on MariaDB 10.1.1 on Mac OS 10.10.5, installed via Homebrew:

Can't open shared library '/usr/local/Cellar/mariadb/10.1.10/lib/plugin/ha_oqgraph.so' (errno: 2, dlopen(/usr/local/Cellar/mariadb/10.1.10/lib/plugin/ha_oqgraph.so, 2): no suitable image found.  Did find:
	/usr/local/Cellar/ma)

/usr/include/sys/errno.h implies that the file doesn't exist, but I can see it seems to have the same perms as other plugins that can be INSTALLed (such as CONNECT):

Any clues what's going on here?

If you google for "Can't open shared library no suitable image found" you'll find quite a few hints of might be the reason. Start from

$ file /usr/local/Cellar/mariadb/10.1.10/lib/plugin/ha_*.so

What did you get?

Thanks for the pointer, which I will investigate further.

file(1) shows that all the ha_*.so libs are "Mach-O 64-bit bundle x86_64", EXCEPT ha_oqgraph.so, which is "Mach-O 64-bit object x86_64".

Did you build MariaDB as in here or installed as in here?

I had done a "brew install maraidb", on top of a previous install. But I a sum(1) on that file and the oqgraph from 10.1.6, and they are the same. So I may have some crufty old stuff hanging around somehow.

I just did a clean "brew install mariadb" on another machine. No ha_oqgraph.so gets installed:

What has to be done to get ha_oqgraph.so built? I'm willing to hack around on the Homebrew formula if I have a good starting point.

From looking at "brew edit mariadb", is it as simple as setting the compile flag: "-DPLUGIN_OQGRAPH=YES"?

Thanks for any advice offered!
