When building bitcoind on LinuxCoin (Debian based), I receive this error

"headers.h:36:20: fatal error: db_cxx.h: No such file or directory"

following the instructions at https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.txt

I believe the error is caused by the package "libdb4.8++-dev" being non-existant for the distro, as when attempting to "apt-get install" that, I get:

Package libdb4.8++-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'libdb4.8++-dev' has no installation candidate

NOTE: libdb4.8-dev and all other dependencies are already installed.

It's probably a silly mistake on my part but any help is appreciated! Thanks.

  • Do you have a db_cxx.h file anywhere? You can check with locate.

  • No. I used to have the db-5.1.8 version but I removed that as the readme said I needed 4.8.

  • If you don't have libdb-devel installed, it won't compile. You can use 5.1.8, just realize your files won't be compatible with builds made with earlier versions.

  • Yeah. I've redownloaded and compiled 5.1.8 now and that's all okay but I'm getting the same error. Not sure how to tweak this makefile to include the db5.1.8 directories

  • The makefile I am using is: pastebin.com/wGpPNjEb. My db-5.1.8 directories are located at /usr/local/BerkeleyDB.5.1/

You need to add -I <directory> to the end of the CXX=g++ line in the Makefile. The directory should be the one that contains the db_cxx.h file from your BerkeleyDB installation. So, change:

CXX=g++

to

CXX=g++ -I /usr/local/BerkeleyDB.5.1

You may need a /include or something like that on the end of that. It depends exactly which directory holds the db_cxx.h file.

I did the following command on Ubuntu and it worked.

sudo apt-get install libdb++-dev

I think you can install the libdb4.8++-dev package if you add the stable debian repo in your sources.list.

I did it on my system (debian sid), and now I can proceed to the installation. I haven't tested the full bitcoind compilation yet, though.

    libdb5.1++-dev also works, for those who would rather install later versions of packages. +1 thanks!

it compiles nice with later versions but be carefull and do not mix up db*-dev and db*++-dev. Here you have to install the "++" version

  • Thanks, that's what I was missing ,db*++-dev instead of db*-dev

Try this:

sudo apt-get install libdb5.3++-dev

The latest stable package, I used this on the new Bitcoin-Qt 8.3 patch from GIT and it compiled flawlessly, for any files that had that as an include.

Note:

If you are using gcc / g++ version 4.8 and you were looking for libdb4.8++-dev, there is a reason why you couldn't find an installation candidate.

Don't confuse the libdb5.3++-dev package with the version of the gcc / g++ compiler and linker, they're not part of the gcc / g++ but an add-on development library regardless of what version of the compiler you use.

If you're building under homebrew on MacOS, install the requisite header files via

brew install berkeley-db
