From f9c026a85b129328be8ed9ce74f19fc0065454be Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Fri, 13 Oct 2006 09:43:29 +0000 Subject: PR binutils/2876 * configure.in: Check for the mkstemp and mkdtemp functions. * configure: Regenerate. * config.in (HAVE_MKDTEMP): New potential define. (MAKE_MKSTEMP): Likewise. * bucomm.c (make_tempname): Use mkstemp if it is available. * make_tempdir): New function: Create a temporary directory using mkdtemp, if it is available. * bucomm.h (make_tempdir): New prototype. * objcopy.c (copy_archive): Use make_tempdir if it is available. (strip_main): Produce an warning message if a temporary file could not be (copy_main): Likewise. * ar.c (write_archive): Likewise. --- binutils/configure | 196 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 196 insertions(+) (limited to 'binutils/configure') diff --git a/binutils/configure b/binutils/configure index e74cb9d..83e632d 100755 --- a/binutils/configure +++ b/binutils/configure @@ -7110,6 +7110,202 @@ _ACEOF fi done +echo "$as_me:$LINENO: checking for mkstemp" >&5 +echo $ECHO_N "checking for mkstemp... $ECHO_C" >&6 +if test "${ac_cv_func_mkstemp+set}" = set; then + echo $ECHO_N "(cached) $ECHO_C" >&6 +else + cat >conftest.$ac_ext <<_ACEOF +/* confdefs.h. */ +_ACEOF +cat confdefs.h >>conftest.$ac_ext +cat >>conftest.$ac_ext <<_ACEOF +/* end confdefs.h. */ +/* Define mkstemp to an innocuous variant, in case declares mkstemp. + For example, HP-UX 11i declares gettimeofday. */ +#define mkstemp innocuous_mkstemp + +/* System header to define __stub macros and hopefully few prototypes, + which can conflict with char mkstemp (); below. + Prefer to if __STDC__ is defined, since + exists even on freestanding compilers. */ + +#ifdef __STDC__ +# include +#else +# include +#endif + +#undef mkstemp + +/* Override any gcc2 internal prototype to avoid an error. */ +#ifdef __cplusplus +extern "C" +{ +#endif +/* We use char because int might match the return type of a gcc2 + builtin and then its argument prototype would still apply. */ +char mkstemp (); +/* The GNU C library defines this for functions which it implements + to always fail with ENOSYS.
