I see that having download links to all the dependencies is useful in particular when trying to build the Berkeley DB part of Bitcoin Core yourself, because it's so ancient that newer versions of BDB are incompatible with anything bitcoin-related, at least from the projects I try odd to compile, and will generate linking errors during compilation.

So I thought it would be useful to have separate instructions for building BDB by itself on Linux.

Code:

pushd /tmp
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
tar -xvf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix. # see [1]
../dist/configure --prefix=/usr/local. # see [2]
make
make install
popd   # changes you back to wherever folder you were in before

[1] Yes, you absolutely have to build Berkeley DB in this folder, otherwise it will spit out an error like this:

Code:

checking if building in the top-level or dist directories... yes
configure: error: Berkeley DB should not be built in the top-level or "dist" directories. Change directory to the build_unix directory and run ../dist/configure from there.

[2] It installs it to /usr/local so that it does not conflict with any system-wise installation of Berkeley DB.

Now to compile stuff with it just pass -I/usr/local/include -L/usr/local/lib -ldb to gcc. And then you run your program like this:

Code:

LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH program-name

Code:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
# many commands later...
program-name

The latter is useful to put in your .bash_profile or .bashrc so that it's automatically set for you at login.

Failing to set LD_LIBRARY_PATH will give you the following error when you start your program:

Code:

error while loading shared libraries: libdb-4.8.so: cannot open shared object file: No such file or directory

Thank you very much for the feedback!
As you can see in the title, I tried to specify that it is for Windows systems and not separately for Bitcoin, but any other type of currency that follows the same compilation line of the tutorial provided by our friend nitrogenetics.

Note that I also informed that the dependencies can be different depending on the project you are looking to work on, a lot can change in different versions of projects. In any case, the dependencies and versions must be the same as those described in the project documentation you are looking to use.

This tutorial is based on the topic of our friend nitrogenetics, which is found at the link.

System used in the tutorial: Windows 10 x64 / build 19042.746 / version 20H2

System Preparation
01 - Install Msys2 Shell:
Download: https://www.msys2.org/

02 - Update Msys2
After downloading and installing the program, run the msys2.exe application and run the following commands:

Code:

pacman -Syu

As soon as the first update is performed, close and reopen msys2.exe. Run the commands:

Code:

pacman -Su
pacman -S git make
pacman -S --needed base-devel mingw-w64-i686-toolchain mingw-w64-x86_64-toolchain \
git subversion mercurial \
mingw-w64-i686-cmake mingw-w64-x86_64-cmake
pacman -S mingw-w64-x86_64-make mingw-w64-i686-make
pacman -S mingw-w64-x86_64-zlib mingw-w64-i868-zlib

Add the MinGW path to the system variables, being added to the PATH option of the operating system. In Windows 10 the path should look like the example below:

32BITS

Code:

C:\msys64\mingw32\bin

64BITS

Code:

C:\msys64\mingw64\bin

Download, extract and build the dependencies:
