Installation of Snapshot

[Note]

Note

This package takes a long time to build because LTO is enabled, and the LTO pass is not parallelized.

First, remove a check against the system Pango version that is too strict: 

sed '/pango.v1_52/,+1d' -i vendor/pango-sys/Cargo.toml &&

cat >> Cargo.toml << EOF
[patch.crates-io.pango-sys]
path = "vendor/pango-sys"
EOF

Install Snapshot by running the following commands: 

mkdir build &&
cd    build &&

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

To test the results, issue: ninja test. One test is known to fail due to deprecated constructs in appstream-1.0+

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.
