Running "./configure" reports the below error: configure: error: Found Berkeley DB other than 4.8, required for portable wallets (--with-incompatible-bdb to ignore)

Naturally, libdb-4.8 is needed for wallet portability, hence, need to resolve this issue. Please help (add instructions) on how to install Berkeley DB 4.8 manually.

The default Berkeley DB on Debian Wheezy is 5.1.

No, please visit the Berkeley DB website for instructions on installing BDB.

I used the below instruction from http://www.peercointalk.org/index.php?topic=798.0 link:

Get db4.8 source, compile and install

wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install

Tell your system where to find db4.8

export BDB_INCLUDE_PATH="/usr/local/BerkeleyDB.4.8/include" export BDB_LIB_PATH="/usr/local/BerkeleyDB.4.8/lib" ln -s /usr/local/BerkeleyDB.4.8/lib/libdb-4.8.so /usr/lib/libdb-4.8.so

ln -s /usr/local/BerkeleyDB.4.8/lib/libdb_cxx-4.8.so /usr/lib/libdb_cxx-4.8.so

Unfortunately, the result is the same.

There should be an option to tell ./configure where it can find the BDB headers / libraries but it doesn't seem to exist.

This is where it searches for the BDB 4.8 lib: https://github.com/bitcoin/bitcoin/blob/master/src/m4/bitcoin_find_bdb48.m4

Can you try:

./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"

It's ugly but the only way at this moment, I think.

./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"

Might be ugly but it worked on Debian Wheezy. I followed link and instructions from kostaz (on february 16 's comment on this page) to successfully compile BerkeleyDB 4.8.

@jeromecc There have been instructions in the UNIX build documentation for a while for building BDB 4.8: https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md#berkeley-db I suggest following those as they don't install BerkeleyDB system-wide.

How hard is it to support latest version of db?

The issue is that newer versions of bdb produce wallet files which are not backward compatible, thus will not load in official binaries using 4.8. If you don't care about this, you can configure using --with-incompatible-bdb to force it to use a newer version. Another alternative is --disable-wallet to avoid the bdb dependency altogether.

With checkinstall you can do this:

wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
tar -xzvf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix
../dist/configure --enable-cxx --prefix=/usr
make -j8
sudo checkinstall --fstrans=no --pkgversion=4.8.30 --pkgname=libdb-dev --nodoc -y

This puts bdb in the system as a Debian package where bitcoin can find it. Note, this only works if you don't already have another version of libbd-dev installed.

You can remove it later with:

sudo dpkg -r libdb-dev

sudo checkinstall --fstrans=no --pkgversion=4.8.30 --pgkname=libdb-dev --nodoc -y

Just a note, there is a typo in @jcoffland's last command. It should be

sudo checkinstall --fstrans=no --pkgversion=4.8.30 --pkgname=libdb-dev --nodoc -y

Thanks @tsusanka, I've edited the comment above as well.

Thanks dear @fanquake and dear @jcoffland but checkinstall is not a command is writting

its ok! ./autogen.sh && ./configure --with-incompatible-bdb && make

same here on ubuntu 16.04. is this safe with this command?

./configure --with-incompatible-bdb
