MySQL?

GNU Radio
1

Dear All,

Has anyone tried using MySQL from GNU Radio? I am just posting some
simple stuff to a MySQL database that runs fine in a stand-alone C
program. It builds fine in GNU Radio, by including <mysql.h>, but there
is a swig problem on running in GNU Radio Companion

“ImportError: /usr/local/lib/libgnuradio-trl.so: undefined symbol:
mysql_init”

Presumably I need to add some libraries to the CMakeLists.txt, or
similar?

Thanks in advance!

David

David,

is the MySQL include in any of your public headers, and does it need to
be? It might be SWIG is picking up stuff you don’t actually want to pick
up.

You can also tell SWIG to ignore stuff, have you checked that?

Hi Martin, All,

It was a basic linker problem, I hadn’t correctly included the library
file in the /lib/CMakeFiles.txt, one needs to include just mysqlclient
(and the linker directory of course)

Sorry! I wonder if anyone else has use MySQL before with GNU Radio - if
not IT WORKS!!

Thanks,

DH
