Thats the reason I went with the alternative approach which is safer although the function is copied twice. > > > configure.ac | 11 ++++++++++- > > mesh/mesh-config-json.c | 4 +++- > > mesh/missing.h | 21 +++++++++++++++++++++ > > mesh/rpl.c | 1 + > > tools/hex2hcd.c | 1 + > > tools/missing.h | 21 +++++++++++++++++++++ > > 6 files changed, 57 insertions(+), 2 deletions(-) > > create mode 100644 mesh/missing.h > > create mode 100644 tools/missing.h > > > > diff --git a/configure.ac b/configure.ac > > index d31eb1656..f0f1ec100 100644 > > --- a/configure.ac > > +++ b/configure.ac > > @@ -70,7 +70,16 @@ AC_CHECK_LIB(pthread, pthread_create, dummy=yes, > > AC_CHECK_LIB(dl, dlopen, dummy=yes, > > AC_MSG_ERROR(dynamic linking loader is required)) > > > > -AC_CHECK_HEADERS(linux/types.h linux/if_alg.h linux/uinput.h linux/uhid.h sys/random.h) > > +AC_CHECK_HEADERS(string.h linux/types.h linux/if_alg.h linux/uinput.h linux/uhid.h sys/random.h) > > + > > +# basename may be only available in libgen.h with the POSIX behavior, > > +# not desired here > > +AC_CHECK_DECLS([basename], [], > > + AC_MSG_WARN([GNU basename extension not found]), > > + [#define _GNU_SOURCE 1 > > + #include <string.h> > > + ]) > > + > > > > PKG_CHECK_MODULES(GLIB, glib-2.0 >= 2.28) > > > > diff --git a/mesh/mesh-config-json.c b/mesh/mesh-config-json.c > > index c198627c6..e3b0a1809 100644 > > --- a/mesh/mesh-config-json.c > > +++ b/mesh/mesh-config-json.c > > @@ -28,6 +28,7 @@ > > #include <ell/ell.h> > > #include <json-c/json.h> > > > > +#include "mesh/missing.h" > > #include "mesh/mesh-defs.h" > > #include "mesh/util.h" > > #include "mesh/mesh-config.h" > > @@ -2694,7 +2695,8 @@ bool mesh_config_load_nodes(const char *cfgdir_name, mesh_config_node_func_t cb, > > > > void mesh_config_destroy_nvm(struct mesh_config *cfg) > > { > > - char *node_dir, *node_name; > > + char *node_dir; > > + const char* node_name; > > char uuid[33]; > > > > if (!cfg) > > diff --git a/mesh/missing.h b/mesh/missing.h > > new file mode 100644 > > index 000000000..eaf32815e > > --- /dev/null > > +++ b/mesh/missing.h > > @@ -0,0 +1,21 @@ > > +// SPDX-License-Identifier: LGPL-2.1-or-later > > +/* > > + * > > + * BlueZ - Bluetooth protocol stack for Linux > > + * > > + * Copyright (C) 2024 Khem Raj <raj.khem@xxxxxxxxx> > > + * > > + */ > > + > > +#ifdef HAVE_CONFIG_H > > +#include <config.h> > > +#endif > > +#if !HAVE_DECL_BASENAME > > +#include <string.h> > > +static inline const char *basename(const char *path) > > +{ > > + const char *base = strrchr(path, '/'); > > + > > + return base ? base + 1 : path; > > +} > > +#endif > > diff --git a/mesh/rpl.c b/mesh/rpl.c > > index fb225dddd..2fa17d72f 100644 > > --- a/mesh/rpl.c > > +++ b/mesh/rpl.c > > @@ -24,6 +24,7 @@ > > > > #include <ell/ell.h> > > > > +#include "mesh/missing.h" > > #include "mesh/mesh-defs.h" > > > > #include "mesh/node.h" > > diff --git a/tools/hex2hcd.c b/tools/hex2hcd.c > > index e6dca5a81..452ab2beb 100644 > > --- a/tools/hex2hcd.c > > +++ b/tools/hex2hcd.c > > @@ -24,6 +24,7 @@ > > #include <stdlib.h> > > #include <stdbool.h> > > #include <sys/stat.h> > > +#include "tools/missing.h" > > > > static ssize_t process_record(int fd, const char *line, uint16_t *upper_addr) > > { > > diff --git a/tools/missing.h b/tools/missing.h > > new file mode 100644 > > index 000000000..eaf32815e > > --- /dev/null > > +++ b/tools/missing.h > > @@ -0,0 +1,21 @@ > > +// SPDX-License-Identifier: LGPL-2.1-or-later > > +/* > > + * > > + * BlueZ - Bluetooth protocol stack for Linux > > + * > > + * Copyright (C) 2024 Khem Raj <raj.khem@xxxxxxxxx> > > + * > > + */ > > + > > +#ifdef HAVE_CONFIG_H > > +#include <config.h> > > +#endif > > +#if !HAVE_DECL_BASENAME > > +#include <string.h> > > +static inline const char *basename(const char *path) > > +{ > > + const char *base = strrchr(path, '/'); > > + > > + return base ? base + 1 : path; > > +} > > +#endif > > > > > -- > Luiz Augusto von Dentz
