From Bitcoin Core's test directory (bitcoin/src/test), the executable test_bitcoin is supposed to run the unit tests. When I run test_bitcoin, however, I get:

replication requires locking support
Test setup error: std::runtime_error: CDBEnv::MakeMock : Error 22 opening database environment.

How can I run test_bitcoin? I installed Bitcoin from source.

Also:

I ran configure using the --with-incompatible-bdb flag.

  • Why don't you install the correct version of bdb? I have the correct .debs in this repository: github.com/nickodell/build_bitcoin Does that fix it?

  • It's complaining that you already have a different version of libdb installed.

    @NickODell I got it to work by uninstalling libdb5.3. I also had to reinstall the 64 bit version of libdb4.8-dev due to some packaging problem, but now it is working. Thanks! Also: how should this be written up as an answer so that users can see that this question already has been answered?

Try installing the correct version of BerkleyDB. (4.8) I have the correct .debs in this repository:

You may need to uninstall the newer version of libdb first.
