Compiling DB Berkeley for Open Cobol

Now, Cygwin is installed on your computer, you must think to compile all dependencies of Open Cobol.

For this, we deposit all files in a sub folder 'tools' in c:\, and inside, the folder containing sources et binaries.

Here is how it give :


c:\

• tools

• src
• bin
  

we take all sources on a sub folder c:\tools\src and the compilation make installation on c:\tools\bin\


All sources of DB Berkeley are on the Oracle's site here
Warning: Open Cobol need the version 4.5 maximum for compiling.
The file who have downloaded with Firefox is 'db-4.5.20.NC.tar.gz'

I have copied this file into c:\tools\src\


in Cygwin:

cd c:
cd tools
mkdir bin
mkdir src
cd src
tar -xzvf db-4.5.20.NC.tar.gz
cd db-4.5.20.NC
cd build_unix
../dist/configure --prefix=/cygdrive/c/tools/bin/db-4.5.20.NC

After this,when all is done, launch the compilation with :

make

That's can take some time.

You can find several documentation on the folder c:\tools\src\db-4.5.20.NC\docs\ (seeing with a browser)

When the compilation is finished , launch the command :

make install

For easy made, it's most easy than using symbolic link who see the last version installed on the computer.(UNIX/Linux functionality :-}) )

ln -s /cygdrive/c/tools/bin/db-4.5.20.NC /cygdrive/c/tools/bin/db

Normally, You must have 4 sub folders:

• bin
• lib
• include
• docs

the Most important is 'lib'

See you on the next lesson for the 'gmp' compile.
