Dmitry V. Levin	c9ace844ba	build: rewrite libdw detection without pkg-config ... pkg-config expected to be more convenient way to configure libdw, but in practice it appeared to be less portable than good old AC_CHECK_HEADERS and AC_CHECK_LIB. * ci/install-dependencies.sh (common_packages): Remove pkg-config. (STACKTRACE == "libdw"): Do not install libz-dev and liblzma-dev. * debian/control (Build-Depends): Remove pkg-config. * m4/st_libdw.m4 (st_ARG_LIBDW, st_LIBDW): Rewrite without pkg-config.	2018-05-05 14:38:38 +00:00
Masatake YAMATO	ddb5a4ba73	unwind: add libdw as an unwinder ... Implement alternative libdw-based unwinder for stack tracing. Add --with-libdw configure option to control whether libdw can be used as an unwinder. * m4/st_libdw.m4: New file. * m4/st_stacktrace.m4 (st_STACKTRACE): Invoke st_ARG_LIBDW and st_LIBDW, check for mutually exclusive configure options, (AM_CONDITIONAL): Add USE_LIBDW. * unwind-libdw.c: New file. * Makefile.am [USE_LIBDW] (strace_SOURCES): Append unwind-libdw.c. [USE_LIBDW] (strace_CPPFLAGS): Append $(libdw_CPPFLAGS). [USE_LIBDW] (strace_CFLAGS): Append $(libdw_CFLAGS). [USE_LIBDW] (strace_LDFLAGS): Append $(libdw_LDFLAGS). [USE_LIBDW] (strace_LDADD): Append $(libdw_LIBS). * NEWS: Mention this improvement.
