[odb-users] warning: ignoring #pragma db object [-Wunknown-pramas]

[Menashe Rosemberg]

Hi Boris,
Thanks for the fast response man.
I installed the odb from command line and it didn't install "apt-get install odb" and I didn't find the libodb and libobd-mysql... at least I didn't find it on my pc.
I checked the libodb-dev andlibodb-mysql-dev packages and the apt-get says I have installed the newest version.
I know I can download the libs from ODB Download, but it a good practice to keep using the Ubuntu default installation in my opinion.

Can you help with that? And how to link it using the Code::Blocks IDE?
May I suggest to include this solutions on your site? More specifically on Linux/UNIX?
I think you will reach more users if you describe step by step how to work with ODB on ubuntu/Code::Blocks environment.
Again, thanks for your attention and your work on this tool.
Best regards,
M.Rosemberg

The C++ compiler should ignore ODB pragmas. They are only interpreted by the
ODB compiler. You may want to add -Wno-unknown-pragmas option to suppress
these warnings.

And this is your actual problem: I believe you are not linking to libodb-mysql
and libodb.
