Sometimes it's useful to have a static-only toolchain. This can be due to targetting some weird embedded platform, or it can be because it ensures that no dynamic libraries are sneaking into a system that's supposed to be 100% static due to non-cooperative build systems. Most build systems support static-only builds, e.g. autoconf provides a --disable-shared configure option. selinux's custom make-based build system did not support such an option, so here I've added one. Apart from the obvious changes, I had to make the utilities that use external libraries link against them manually, because that can't be inferred from the static selinux libraries. For downstream users of libselinux using pkg-config, this shouldn't be a problem, because libselinux.pc already includes the Requires.private line that specifies libpcre should be linked against as well. Signed-off-by: Alyssa Ross <hi@xxxxxxxxx> --- Changes since v1: • Moved libselinux.a ahead of -lpcre in the linker arguments for sefcontext_compile in libselinux/utils/Makefile, as suggested by Nicolas Iooss, to hopefully fix CI. • Fixed static-only builds of libsemanage and policycoreutils, in addition to libsepol and libselinux. I've also tested building checkpolicy and semodule-utils, which worked without any further changes. v1: https://lore.kernel.org/selinux/20211111164229.9711-1-hi@xxxxxxxxx/ libselinux/src/Makefile | 11 ++++++++--- libselinux/utils/Makefile | 7 ++++++- libsemanage/src/Makefile | 9 +++++++-- libsepol/src/Makefile | 11 ++++++++--- policycoreutils/load_policy/Makefile | 2 +- policycoreutils/semodule/Makefile | 3 ++- policycoreutils/setfiles/Makefile | 2 ++ policycoreutils/setsebool/Makefile | 3 ++- 8 files changed, 36 insertions(+), 12 deletions(-) diff --git a/libselinux/src/Makefile b/libselinux/src/Makefile index 52c40f01..814012e1 100644 --- a/libselinux/src/Makefile +++ b/libselinux/src/Makefile @@ -136,7 +136,10 @@ endif SWIGRUBY = swig -Wall -ruby -o $(SWIGRUBYCOUT) -outdir ./ $(DISABLE_FLAGS) -all: $(LIBA) $(LIBSO) $(LIBPC) +all: $(LIBA) $(LIBPC) +ifneq ($(DISABLE_SHARED),y) +all: $(LIBSO) +endif pywrap: all selinuxswig_python_exception.i CFLAGS="$(CFLAGS) $(SWIG_CFLAGS)" $(PYTHON) setup.py build_ext @@ -175,11 +178,13 @@ $(SWIGRUBYCOUT): $(SWIGRUBYIF) install: all test -d $(DESTDIR)$(LIBDIR) || install -m 755 -d $(DESTDIR)$(LIBDIR) install -m 644 $(LIBA) $(DESTDIR)$(LIBDIR) -
