rtems-tools on CentOS 7 Build Failure

[Joel Sherrill]

A build failure for rtems-tools on the master has been reported on CentOS 7. This is my notes as I try to reproduce it.

==================================================================
Looking down into libiberty.h, I picked on basename()

/* HAVE_DECL_* is a three-state macro: undefined, 0 or 1. If it is

undefined, we haven't run the autoconf check so provide the
declaration without arguments. If it is 0, we checked and failed
to find the declaration so provide a fully prototyped one. If it
is 1, we found it so don't provide any declaration at all. */

#if !HAVE_DECL_BASENAME

#if defined (GNU_LIBRARY )

defined (linux) \

defined (FreeBSD)	defined (OpenBSD)	defined (NetBSD) \
defined (CYGWIN)	defined (CYGWIN32)	defined (MINGW32) \
defined (DragonFly)	defined (HAVE_DECL_BASENAME)

extern char *basename (const char *) ATTRIBUTE_RETURNS_NONNULL ATTRIBUTE_NONNULL(1);
#else
/* Do not allow basename to be used if there is no prototype seen. We

either need to use the above prototype or have one from
autoconf which would result in HAVE_DECL_BASENAME being set. */

#define basename basename_cannot_be_used_without_a_prototype
#endif
#endif
============================================
The native CentOS 7 has this definition of basename:

# ifndef basename
/* Return the file name within directory of FILENAME. We don't

declare the function if the `basename' macro is available (defined
in <libgen.h>) which makes the XPG version of this function
available. */

# ifdef CORRECT_ISO_CPP_STRING_H_PROTO
extern "C++" char *basename (char *filename)

THROW asm ("basename") nonnull ((1));

extern "C++" const char *basename (const char *filename)

THROW asm ("basename") nonnull ((1));

# else
extern char *basename (const char *filename) THROW nonnull ((1));
# endif
# endif
#endif

==============================
I think we are getting the C++ prototype from string.h and a conflicting C prototype from libiberty.h

[Chris Johns <chrisj@…>]

In f2bb439/rtems-tools:

rtemstoolkit/libiberty: Fix broken configure detection.

The file libiberty.h requires some configure macros to control some parts
and these are not provided so the file did not match what was needed. Hard
code the result and remove the need for the macros. The related calls
are not provided in our libiberty usage and not needed.

Closes #3103.
