Command Explanations

• make $LWI_MAKE_FLAGS: Builds bsdpatch with the shared make parallelism setting.
• CC="$LBI_ROOT/system/tools/bin/$LBI_TARGET-clang": Uses the target-prefixed Clang compiler.
• CFLAGS="--target=$LBI_TARGET --sysroot=$LBI_ROOT $LWI_CFLAGS": Targets the selected triple/sysroot and preserves local C flag tuning.
• LDFLAGS="--target=$LBI_TARGET --sysroot=$LBI_ROOT $LBI_CUSTOM_LDFLAGS": Keeps link steps inside the target sysroot while preserving local linker tuning.
• make install DESTDIR="$LBI_ROOT": Installs into the target root instead of the host system.
• PREFIX=/system and BINDIR=/system/binaries: Place the installed command in the book's binary layout.
• DATADIR=/system/documentation and MANDIR=/system/documentation/man-pages/man1: Place support documentation and the manual page in the book's documentation tree.
• INSTALL_NAME=patch: Installs the program under the standard patch command name.
