8.20. bmake 20260406

Install the portable NetBSD make implementation for packages that expect BSD make behavior.

Input assumption: bmake-20260406.tar.gz is already present in /sources from the chapter 4 source staging step.

Source URL: https://www.crufty.net/ftp/pub/sjg/bmake-20260406.tar.gz

Upstream build note: upstream documents ./bmake/boot-strap as the preferred bootstrap path and also supports the standard ./configure, make, and make install flow. This section uses lbi_configure because the generated configure script accepts the book's standard installation directory options, then uses the newly built bmake for installation so the book's directory layout is applied consistently.

Licenses:

BSD-2-Clause

Dependencies:

musl (libc)
make

bmake is a portable NetBSD make implementation. we need it to provide BSD make semantics and the accompanying mk include files for packages that are written for BSD-style makefiles.

Extract and Enter the Source Tree

cd /sources
rm -rf bmake
tar -xf bmake-20260406.tar.gz
cd bmake

Configure bmake

lbi_configure \
    --with-default-sys-path=/system/share/mk \
    --with-mksrc=mk \
    --with-filemon=no \
    --without-lua

Build bmake

make $LWI_MAKE_FLAGS

Install bmake

MAKESYSPATH=mk \
./bmake -f Makefile install \
    prefix=/system \
    BINDIR.bmake=/system/binaries \
    SHAREDIR.bmake=/system/share \
    MANDIR.bmake=/system/documentation/man-pages \
    STRIP_FLAG=

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

Command Explanations

rm -rf bmake and tar -xf: Recreate a clean bmake source tree.
lbi_configure: Applies the book's /system install layout.
--with-default-sys-path=/system/share/mk: Sets the default makefile include path.
--with-mksrc=mk: Points bmake at its bundled mk files.
--with-filemon=no and --without-lua: Disable optional filemon and Lua support.
make $LWI_MAKE_FLAGS: Builds bmake with shared make parallelism.
MAKESYSPATH=mk ./bmake -f Makefile install: Uses the newly built bmake and bundled mk files for installation.
BINDIR.bmake, SHAREDIR.bmake, and MANDIR.bmake: Install bmake files into the book's layout.
