Usage:
\$ $0 [--enable-*|--disable-*] [--with-*|--without-*] [CC=...] [...]
\$ $MAKE -j$(nproc)
Variables set in the environment or on the command line will be picked up:
MAKE
The make implementation to use
CC
The C compiler to use
CPPFLAGS="-I... -D..."
CFLAGS="-W... -f..."
LDFLAGS="-L... -Wl,..."
Preprocessor/compiler/linker flags
LDLIBS="-l... -l..."
Dynamic libraries to link
EXTRA_{CPPFLAGS,CFLAGS,LDFLAGS,LDLIBS}
Adds to the default flags, instead of replacing them
The default flags result in a plain debug build. Other build profiles include:
--enable-release
Enable optimizations, disable assertions
--enable-{asan,lsan,msan,tsan,ubsan}
Enable sanitizers
--enable-gcov
Enable code coverage instrumentation
External dependencies are auto-detected by default, but you can build --with or
--without them explicitly:
--with-libacl --without-libacl
--with-libcap --without-libcap
--with-libselinux --without-libselinux
--with-liburing --without-liburing
--with-oniguruma --without-oniguruma
Packaging:
--prefix=/path
Set the installation prefix (default: /usr)
--mandir=/path
Set the man page directory (default: \$PREFIX/share/man)
--version=X.Y.Z
Set the version string (default: $("$DIR/build/version.sh"))
This script is a thin wrapper around a makefile-based configuration system.
Any other arguments will be passed directly to the $MAKE invocation, e.g.
\$ $0 -j$(nproc) V=1
