[odb-users] Installing ODB Compiler

[Nathan White]

I'm receiving this error "Error unknown database; did you forget to define the DATABASE_* macros?"

What is DATABASE_* macros?  

I guessed at what the error is and changed 

#ifndef DATABASE_HXX
#define DATABASE_HXX

To 

#ifndef odbtest
#define odbtest

Regards,
Nathan


-------------------------------
I solved the initial problem of not being able to create peron-odb files.  My issue with creating the person-odb files stemmed from me not being in the exact folder where person.hxx is stored.  It was the last configuration I tried.  Thank you for helping me through this issue.  As I am a new Ubuntu, odb, and SQLite user there are many unknowns for me so I often have a lot of questions.    

Regards,
Nathan

In this case you should be able to install directly from the package:

sudo dpkg -i odb_2.2.0-1_i386.deb

Have you tried this? If it didn't work, what was the error?

The advantage of using the package instead of the archive is that the ODB compiler will be installed in the default location and you will be able to invoke it just as odb, for example:

odb -d sqlite person.hxx

person.hxx is a C++ header from the hello example that used in the sample command lines. Normally, you would have your own header with your own persistent classes. If you want to use person.hxx (e.g., to test the ODB compiler), then you can find it in the hello/ subdirectory in the odb-examples package.

You don't need to use sudo when invoking the ODB compiler.
