+
+ * configure.ac: Add --enable-libctf: handle --disable-static
+ properly.
+ * acinclude.m4: sinclude ../config/enable.m4.
+ * Makefile.in (aclocal_m4_deps): Adjust accordingly.
+ (LIBCTF): Substitute in.
+ (CTF_DEPS): New, likewise.
+ (CLIBS): libctf needs symbols from libbfd: move earlier.
+ (CDEPS): Use CTF_DEPS, not LIBCTF, now LIBCTF can include rpath
+ flags.
+ * ctfread.c: Surround in ENABLE_LIBCTF.
+ (elfctf_build_psymtabs) [!ENABLE_LIBCTF]: New stub.
+ * configure: Regenerate.
+ * config.in: Likewise.
+
2020-06-25 Simon Marchi <simon.marchi@efficios.com>
* infcmd.c (set_inferior_io_terminal): Use make_unique_xstrdup.
