## Introduction to libportal

The libportal package provides a library that contains GIO-style async APIs for most Flatpak portals.

This package is known to build and work properly using an LFS 12.2 platform.

- Download size: 76 KB

- Estimated disk space required: 3.0 MB (with tests)

- Estimated build time: 0.1 SBU (add 0.3 SBU for tests)

### Additional Downloads

- Optional patch (required for running the test suite): https://www.linuxfromscratch.org/patches/blfs/12.2/libportal-0.7.1-testsuite_fix-1.patch

### libportal Dependencies

#### Required

GLib-2.80.4 (with GObject Introspection)

#### Recommended

GTK+-3.24.43 and GTK-4.14.5

#### Recommended (Runtime)

To make this package really useful, install xdg-desktop-portal-1.18.2, xdg-desktop-portal-gtk-1.15.1, xdg-desktop-portal-gnome-46.2 (if running a GNOME desktop environment), and xdg-desktop-portal-lxqt-1.0.2 (if running a LXQt desktop environment). They are not needed if only using this package to satisfy a build dependency.

#### Optional

Gi-DocGen-2024.1 (for documentation), dbusmock-0.32.1 and pytest-8.3.2 (for testing), qt5-components-5.15.14 (for the Qt5 version of libportal), and Vala-0.56.17

## Installation of libportal

### Warning

If a previous version of libportal is installed, move the headers out of the way so that later packages do not encounter conflicts (as the `root` user):

    if [ -e /usr/include/libportal ]; then
        rm -rf /usr/include/libportal.old &&
        mv -vf /usr/include/libportal{,.old}
    fi

If running the test suite, apply a patch to fix several test failures with python-dbusmock 0.30.0 or later:

    patch -Np1 -i ../libportal-0.7.1-testsuite_fix-1.patch

Install libportal by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr --buildtype=release -D docs=false .. &&
    ninja

If you have Gi-DocGen-2024.1 installed and wish to build the API documentation for this package, issue:

    sed "/output/s/-1/-0.7.1/" -i ../doc/meson.build &&
    meson configure -D docs=true                   &&
    ninja

To test the results, issue: ninja test. Note that additional `dbus-daemon` processes may need to be killed after the tests are run.

Now, as the `root` user:

    ninja install

## Command Explanations

`--buildtype=release`: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

`-D docs=false`: Allow building this package without Gi-DocGen-2024.1 installed. If you have Gi-DocGen-2024.1 installed and you wish to rebuild and install the API documentation, a meson configure command will reset this option.
