Using Btrieve with Python on Windows x64

Documented below is one approach to configuring the Btrieve 2 SDK for the Python programming language. In this example, we will use Visual Studio 2015 to target a native Windows x64 environment. It is assumed that Zen is already installed and running.

• Install SWIG and Python if not already installed.
  • http://www.swig.org/
  • http://www.python.org/
• Install the Btrieve 2 Windows SDK for Zen.
  • https://esd.actian.com/product/Zen_PSQL/SDKs
• Generate, build, and install Btrieve Python.
  • Open the Visual Studio x64 Native Tools Command Prompt.
  • Change directory into the Btrieve 2 SDK directory.
  • Generate Btrieve Python.
    • c:\swigwin-3.0.12\swig.exe -cppext cpp -outcurrentdir -python -c++ -Iinclude -o btrievePython.cpp swig\btrievePython.swig
      • Note that the path to SWIG used above may differ.
  • Build Btrieve Python.
    • cl -EHsc -c -Iinclude -IC:\Python36\include btrievePython.cpp
    • link -dll win64\x86_64\btrieveCpp.lib -libpath:C:\Python36\libs -out:_btrievePython.pyd btrievePython.obj
      • Note that the path to Python used above may differ.
  • Install Btrieve Python.
    • copy btrievePython.py "c:\Program Files\Actian\Zen\bin"
    • copy _btrievePython.pyd "c:\Program Files\Actian\Zen\bin"
      • You may need elevated permissions to perform these copies.
  • Execute the Btrieve Python sample program.
    • C:\Python36\python.exe samples\btest.py 9
      • You should see the output "record: (9, 81, 3)".
      • Note that the path to Python used above may differ.
      • You may need to change the permissions of the current directory if you receive the error "AssertionError: Error: BtrieveClient.FileCreate():94:Permission error".

Using Btrieve with Python on Ubuntu Linux x64

Documented below is one approach to configuring the Btrieve 2 SDK for the Python programming language. In this example, we will use the Python 3 package to target an Ubuntu Linux x64 environment. It is assumed that Zen is already installed and running.

• Install SWIG and Python if not already installed.
  • Open a terminal window as a non-"root" user.
  • sudo apt install swig
  • sudo apt install python3 python3-dev
• Install the Btrieve 2 Linux SDK for Zen.
  • https://esd.actian.com/product/Zen_PSQL/SDKs
• Generate, build, and install Btrieve Python.
  • Open a terminal window as a non-"root" user.
  • Change directory into the Btrieve 2 SDK directory.
  • Generate Btrieve Python.
    • swig -cppext cpp -outcurrentdir -python -c++ -Iinclude -o btrievePython.cpp swig/btrievePython.swig
  • Build Btrieve Python.
    • g++ -c -fPIC -Iinclude -I/usr/include/python3.8 btrievePython.cpp
    • g++ -shared btrievePython.o -o _btrievePython.so -L/usr/local/actianzen/lib64 -lbtrieveCpp
      • Note that the path to Python used above may differ.
  • Install Btrieve Python.
    • sudo cp btrievePython.py /usr/local/actianzen/lib64
    • sudo cp _btrievePython.so /usr/local/actianzen/lib64
  • Execute the Btrieve Python sample program.
    • export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu:/usr/local/actianzen/lib64
    • python3 samples/btest.py 9
      • You should see the output "record: (9, 81, 3)".
      • Note that Python version 3 is specified.
      • You may need to change the permissions of the current directory if you receive the error "AssertionError: Error: BtrieveClient.FileCreate():94:Permission error".
