8.9. pkgconf 2.5.1

Build and install pkgconf in the final target environment to provide pkg-config-compatible dependency queries.

Input assumption: pkgconf-2.5.1.tar.xz is already present in /sources from the chapter 4 source staging step.

Source URL: https://distfiles.ariadne.space/pkgconf/pkgconf-2.5.1.tar.xz

Upstream build note: upstream documents pkgconf as an autotools-based UNIX build (./configure, make, make install) for release tarballs.

Licenses:

Dependencies:

musl (libc)
make

pkgconf is a compiler and linker flag resolver for pkg-config metadata files. we need it to provide pkg-config-compatible dependency resolution for later package builds in chapter 8.

Extract and Enter the Source Tree

cd /sources
tar -xf pkgconf-2.5.1.tar.xz
cd pkgconf-2.5.1

Configure pkgconf

lbi_configure \
    --with-system-libdir=/system/libraries \
    --with-system-includedir=/system/headers

Build pkgconf

make $LWI_MAKE_FLAGS

Install pkgconf

make install

Install pkg-config compatibility symlink

ln -sf pkgconf /system/binaries/pkg-config
ln -sf pkgconf.1 /system/documentation/man-pages/man1/pkg-config.1

After this step is complete, you can remove the extracted source directory and source tarball from /sources if you do not plan to rebuild pkgconf again.

Command Explanations

cd /sources, tar -xf, and cd pkgconf-...: Enter the staged pkgconf source tree.
lbi_configure: Applies the book's /system install layout.
--with-system-libdir=/system/libraries and --with-system-includedir=/system/headers: Teach pkgconf the target's default library and header locations.
make $LWI_MAKE_FLAGS and make install: Build and install pkgconf.
ln -sf pkgconf ... pkg-config: Provides the common pkg-config command name and manual-page alias.
