 Description   

I tried to compile MariaDB 10.0.16 in CentOS and everything is OK except CONNECT plugin refuses to build. Is this related to the missing linux-vdso.so.1 library present in 3.x kernel or a specific ODBC version?

# ldd /usr/lib64/mysql/plugin/ha_connect.so
 
	linux-vdso.so.1 =>  (0x00007fffeaf62000)
 
	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f7e158e4000)

	libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00007f7e1537b000)
 
	libodbc.so.2 => /usr/lib64/libodbc.so.2 (0x00007f7e15114000)

	libltdl.so.7 => /usr/lib64/libltdl.so.7 (0x00007f7e143e7000)
 
	libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f7e141d1000)

All other libraries are present in my build system.

# uname -a
 
Linux apollo 2.6.32-504.8.1.el6.x86_64 #1 SMP Wed Jan 28 21:11:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
 
# rpm -q unixODBC-devel
 
unixODBC-devel-2.2.14-14.el6.x86_64

As a side note, I noticed the /etc//my.cnf.d/oqgraph.cnf file does not exist by default. I had to create it manually during build time.

[mariadb]
 
plugin-load-add = ha_oqgraph.so

Please paste the actual error you are getting.
Here is our build log of 10.0.16 on CentOS 6 x86_64, as you can see it built fine, connect engine included.

Hi,

With -DWITH_MAX=ON which you have among your cmake options, you have CONNECT engine linked statically. If you start the server and check SHOW ENGINES, it should already be there.

Hi Elena,

Compiling without DWITH_MAX does address the issue, thank you for the fix. However, I miss the related configuration files (i.e. connect.cnf), they are not created by default. In your build, are they created by default? Thank you for helping me solve this issue.

To have it created, you should run cmake with -DRPM=centos6.
