Otherwise, we assume that the numberAdd an implementation of the fts_*() functionsThe fts_*() functions are optional in uClibc, and not compiled in ourdefault configuration. The best option would be to migrate thiselfutils code to the nftw family of functions, but it requires quitesome work.So we have several options here: *) Enable fts_*() functions in our default uClibc configuration. Not nice since only one package needs them (the help text of uClibc for fts_*() functions explicitly mention that they have been added to be able to build elfutils). *) Use gnulib, but it is quite heavy to setup, requires modifications to configure.ac, and other things. *) Copy the fts function from uClibc into elfutils source code. This is the solution used below. uClibc is LGPL, and elfutils is LGPL/GPL, so there should not be any licensing issue.Of course, the fts_*() functions are only built if they are notalready provided by the C library.Based on the former patch by Thomas Petazzoni.Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com>diff -Nrup a/configure.ac b/configure.ac--- a/configure.ac 2015-01-06 11:37:38.397891424 +0000+++ b/configure.ac 2015-01-06 11:40:53.568258759 +0000@@ -266,6 +266,10 @@ AC_ARG_ENABLE([progs], enable_progs=yes) AM_CONDITIONAL(ENABLE_PROGS, test "$enable_progs" = yes) +AC_CHECK_HEADER([fts.h],+ AC_DEFINE([HAVE_FTS_H], [], [Define if <fts.h> is available in C library]))+AM_CONDITIONAL(HAVE_FTS, test "$ac_cv_header_fts_h" = yes)+ dnl Test for zlib and bzlib, gives ZLIB/BZLIB .am dnl conditional and config.h USE_ZLIB/USE_BZLIB #define. save_LIBS="$LIBS"diff -Nrup a/libdwfl/fts.c b/libdwfl/fts.c--- a/libdwfl/fts.c 1970-01-01 01:00:00.000000000 +0100+++ b/libdwfl/fts.c 2015-01-06 11:42:13.481640322 +0000@@ -0,0 +1,1095 @@+/*-+ * Copyright (c) 1990, 1993, 1994+ * The Regents of the University of California.
