Introduction to librsvg

The librsvg package contains a library and tools used to manipulate, convert and view Scalable Vector Graphic (SVG) images.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

librsvg Dependencies

Required

Cairo-1.18.2, gdk-pixbuf-2.42.12, Pango-1.54.0, and rustc-1.81.0

[Note]

Note

An Internet connection is needed for building this package.

Recommended

GLib-2.82.0 (with GObject Introspection) and Vala-0.56.17

Optional

docutils-0.21.2 (for man pages), Gi-DocGen-2024.1 (for documentation), and Xorg Fonts (for tests)

Installation of librsvg

Install librsvg by running the following commands: 

./configure --prefix=/usr    \
            --enable-vala    \
            --disable-static \
            --docdir=/usr/share/doc/librsvg-2.58.3 &&
make

To test the results, issue: 

cargo update --precise 0.3.36 time &&
LC_ALL=C make check -k

All 68 tests should pass.

Now, as the root user: 

make DOC_INSTALL_DIR='$(docdir)' install
[Note]

Note

If you installed the package on to your system using a “DESTDIR” method, an important file was not installed and should be copied and/or generated. Generate it using the following command as the root user: 

gdk-pixbuf-query-loaders --update-cache

Command Explanations

--enable-vala: This switch enables building of the Vala bindings. Remove this switch if you don't have Vala-0.56.17 installed.

--disable-static: This switch prevents installation of static versions of the libraries.

DOC_INSTALL_DIR='$(docdir)': This override ensures installing the API documentation into the expected location if Gi-DocGen-2024.1 is installed.

cargo update --precise=0.3.36 time: This updates the Cargo.lock file to refer to version 0.3.36 of the time crate for the test suite. Originally it refers to version 0.3.34, which fails to build with Rustc-1.80.0 or later.

--disable-introspection: Use this switch if you have not installed Gobject Introspection.

--disable-gtk-doc: This switch prevents building the API documentation, even if Gi-DocGen-2024.1 (despite the name of the option) is available.
