Packaging for Linux distributions#

Requirements#

  • Python

  • MuPDF checkout (including submodules).

  • PyMuPDF checkout.

  • System packages listed in scripts/sysinstall.py:g_sys_packages.

  • Python packages listed in pyproject.toml.

Extra requirements for running tests:

  • Python packages listed in scripts/gh_release.py:test_packages.

General steps#

  • Build and install MuPDF:

    • Install required system packages.

    • Run make install-shared-python on MuPDF’s Makefile with at least these make variables:

      • DESTDIR set to the install directory, e.g. /.

      • prefix set to location relative to DESTDIR, such as /usr/local or /usr. Must start with /.

      • USE_SYSTEM_LIBS=yes.

      • HAVE_LEPTONICA=yes.

      • HAVE_TESSERACT=yes.

  • Build and install PyMuPDF:

    • Run pip install ./PyMuPDF or pip wheel ./PyMuPDF with at least these environment variables:

      • PYMUPDF_SETUP_MUPDF_BUILD= (empty string) to prevent download and build of hard-coded MuPDF release.

      • CFLAGS, CXXFLAGS and LDFLAGS set to allow visibility of the installed MuPDF headers and shared libraries.

  • Run PyMuPDF tests:

    • Ensure required Python packages are available.

    • Run pytest -k "not test_color_count and not test_3050" PyMuPDF

      • Test test_color_count is known fail if MuPDF is not built with PyMuPDF’s custom config.h.

      • Test test_3050 is known to fail if MuPDF is built without its own third-party libraries.

Use of scripts/sysinstall.py#

scripts/sysinstall.py provides a useful example of build, install and test commands that are known to to work, because it is run regularly by Github action .github/workflows/test_sysinstall.yml.

  • Run with -h or look at the doc-string to see detailed usage information.

  • It uses Debian-style apt commands to install system packages.

  • By default it assumes local git checkouts mupdf/ and PyMuPDF/.

To run a full build, install and test for both a local fake root and the system root:

./PyMuPDF/scripts/sysinstall.py
./PyMuPDF/scripts/sysinstall.py --root /

To see what commands would be run without actually running them:

./PyMuPDF/scripts/sysinstall.py -m 0 -p 0 -t 0
