Installing from source:
----------------------
I. General Notes
II. UNIX
III. MS-Windows
I. General Notes:
-----------------
If your platform comes without OpenGL or Forms support, or you just get
into troubles using the default setup script, it is possible to disable
Forms and OpenGl support from the pyFltk build. The following command
line switches are provided for this:
--disable-gl : will disable OpenGL support
--disable-forms : will disable Forms support
In general, however, setup.py will take the proper settings from your Fltk
installation, to be used for the compilation of pyFltk.
II. UNIX:
---------
We've only tested it under Linux (Ubuntu 18, 20.04, 21.04, Debian 11) so far.
1) Pre-requisites
1.1) Install cmake V3.16 (or later)
1.2) Install g++ V9 (or later)
1.3) Install swig-4.0 (or later) Not required if you download pyFltk _WithSwig source
1.5) Download fltk-1.3.8 (or later)
1.6) Download pyFltk-1.3.8 (or later)
2) Building fltk (as shared libraries using CMake)
2.1) Extract fltk to some local directory, e.g. ~\fltk-1.3.8
2.2) Open a terminal and navigate to ~\fltk-1.3.8 (or wherever you installed fltk)
2.3) mkdir build
2.4) cd build
2.5) cmake -D OPTION_BUILD_SHARED_LIBS=ON -D CMAKE_POSITION_INDEPENDENT_CODE=ON ..
2.6) make
2.7) sudo make install
3) Building pyFltk
3.1) Extract pyFltk to some local directory, e.g. ~\pyFltk-1.3.8
3.2) Open a command prompt and change to directory ~\pyFltk-1.3.8 (or wherever you installed pyFltk)
3.3) python3 setup.py swig build (or just "python3 setup.py build" if using the _WithSwig source tarball)
3.4) sudo python3 setup.py install
This will build the wrapper and install it to the Python directores.
You should then be able to swith to fltk/test/ and run the demos by typing: python demos.py
III. MS-Windows:
----------------
MS-Visual C++ under Windows10:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Since Python 3.4, the preferred way of building extensions is with the Microsoft compiler. For this to work you will need the the Microsoft Visaul C++ compiler V14 or later, which can be installed as a free version.
See https://wiki.python.org/moin/WindowsCompilers for how to install this.
1) Pre-requisites
1.1) Install Visual Studio 2019 Community edition (or later)
1.2) Install Python V3.9 64bit (or later)
1.3) Install swigwin-4.0.2 (or later) Not required for the _WithSwig source
1.4) Add swigwin install directory to user or system path
1.5) Download fltk-1.3.8 (or later)
1.6) Download pyFltk-1.3.8 (or later) or the _WithSwig source
2) Building fltk (using CMake)
2.1) Extract fltk to some local directory, e.g. C:\work\fltk-1.3.8
2.2) Start Visual Studio and select "Open a local folder"
2.3) Navigate to C:\work\fltk-1.3.8 (or wherever you installed fltk) and press select
2.4) Visual Studio will now initialize the CMake environment, this might take a few moments
2.5) Create a Release configuration by selecting "Manage Configurations", press "+" and select "x64 Release"
2.6) Build the project for the x64-Release: "Build" -- "Build All"
2.7) After compilation finished, install the project by selecting "Build" -- "Install FLTK"
3) Building pyFltk
3.1) Extract pyFltk to some local directory, e.g. C:\work\pyFltk-1.3.8
3.2) Open a command prompt and change to directory C:\work\pyFltk-1.3.8 (or wherever you installed pyFltk)
3.3) Set the following environment variable by typing: set FLTK_HOME=C:\work\fltk-1.3.8\out\install\x64-Release
3.4) Create and install the wrapper by typing:
python setup.py swig install
or
python setup.py install (if you downloaded pyFltk _WithSwig source)
This will build the wrapper and install it to the Python directores.
You should then be able to switch to test/ and run the demos
by typing: python demos.py
MinGW
~~~~~
Since Python3.4 we do not support MinGW anymore, please use the approch with MS Visual C++ instead.
III. Other Platforms:
---------------------
Proceed according to the above outline.
I would be glad about any feedback if you succeeded with building
pyFltk on any other platform.
