when mining from the wallet I find blocks and get an incoming transaction, but it disappears after 2 seconds and my balance sits at 0. any idea why that is?
Orphans - it means someone else beat you to that block before you found it
checking for Berkeley DB C++ headers... no
configure: error: libdb_cxx headers missing, BitDaric Core requires this library for wallet functionality (--disable-wallet to disable wallet functionality)
You need to install libdb c++
I used libdb4.8-dev.
