Introduction to libsoup3

The libsoup3 is a HTTP client/server library for GNOME. It uses GObject and the GLib main loop to integrate with GNOME applications and it also has an asynchronous API for use in threaded applications.

[Note]

Note

This version of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable version of the System V books.

Installation of libsoup3

First, fix a security vulnerability that could lead to credential leakage: 

patch -Np1 -i ../libsoup-3.6.6-upstream_fixes-1.patch

Fix the installation path of API documentation: 

sed 's/apiversion/soup_version/' -i docs/reference/meson.build

Install libsoup3 by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr          \
            --buildtype=release    \
            --wrap-mode=nofallback \
            ..                     &&
ninja

To test the results, issue: ninja test.

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.

--wrap-mode=nofallback: This switch prevents meson from using subproject fallbacks for any dependency declarations in the build files, preventing it from downloading any optional dependencies which are not installed on the system.

-D docs=enabled: If Gi-DocGen-2026.1 is installed, the API documentation will be built and installed no matter if this option is used or not. This option causes the meson command to fail if Gi-DocGen-2026.1 is not installed.
