8.58. Meson-1.11.1

8.58.1. Installation of Meson

Compile Meson with the following command:

pip3 wheel -w dist --no-cache-dir --no-build-isolation --no-deps $PWD

The test suite requires some packages outside the scope of LFS.

Install the package:

pip3 install --no-index --find-links dist meson
install -vDm644 data/shell-completions/bash/meson /usr/share/bash-completion/completions/meson
install -vDm644 data/shell-completions/zsh/_meson /usr/share/zsh/site-functions/_meson

When targeting the 32-bit architecture on 64-bit, some packages using Meson-based build systems will sometimes use wrong architecture-specific settings, bit sizes, and pull in libraries not meant for the architecture being targeted. This doesn't happen often but requires complex solutions to solve without cross or native files. Errors can range from linking and out-of-bounds, to other various cryptic output.

Cross and native files specify architecture specific information which either honestly and slyly tells Meson what the target or host is so it uses correct information and libraries. Create those files now:

mkdir -pv /usr/share/meson/cross
mkdir -pv /usr/share/meson/native
for i in {cross/lib32,native/x86}; do
cat > /usr/share/meson/$i << "EOF"
[binaries]
c = ['gcc', '-m32']
cpp = ['g++', '-m32']
rust = ['rustc', '--target', 'i686-unknown-linux-gnu']
pkg-config = 'i686-pc-linux-gnu-pkg-config'
ar = '/usr/bin/ar'
strip = '/usr/bin/strip'
cups-config = 'cups-config'
llvm-config = 'llvm-config'
exe_wrapper = ''

[built-in options]
libdir = 'lib32'

[properties]
sizeof_void* = 4
sizeof_long = 4

[host_machine]
system = 'linux'
subsystem = 'linux'
kernel = 'linux'
cpu_family = 'x86'
cpu = 'i686'
endian = 'little'
EOF
done

Note

These files will be used by default in packages that will use Meson-based build systems to reduce any architecture and upgrading issues.
