  Failed test​: 1

Result​: FAIL

NOTE​: Without ccflags using "-D__EXTENSIONS__ -D_POSIX_C_SOURCE=200112L", stuff either did not compile and/or there were lots of warnings.
ccflags.SH added -std=c99 and -D_XPG6 it it was not on the command line, but without -D__EXTENSIONS__ wanted to put in -std=c89 at the same time.
Adding those two flags stopped that result and it had a very clean build.

I don't have access to Solaris 10, but I do know dirfd() is detected on Solaris 11​:

$ perl -V​:d_dirfd
d_dirfd='define';

If you do the above with your system perl, do you get the same result?

I've never needed all those extra defines on Solaris 11, but I normally build with the workshop compiler.

$ perl -V​:d_dirfd
d_dirfd='undef';

I am wondering what is the criteria that Perl is looking for to "define" this?

If I know that I could see why it's failing.

On Solaris Configure appears to search libc with nm, and if not found, build a simple test program to check for the symbol.

Simple things to check​:

- is there a man page for dirfd? 2.11 has one, if 2.10 has the manpage it should have the function

- try forcing d_dirfd enabled​:

  ./Configure ... -Dd_dirfd

  If that fails at link/runtime because it can't find the symbol, then you don't have it.

From looking at other threads, Solaris 8, 9 and 10 and some other OS do not have dirfd...so shouldn't this be "skip" instead of "fail" or at least xfail or some other notice that this it's expected to not work on Solaris 10?

Looking closer at the code, it should be falling back to using the dd_fd member of the DIR structure.

From looking at the headers on OmniOS (which appears to have an older set of headers)​:

#if !defined(__XOPEN_OR_POSIX)

typedef struct {
  int dd_fd; /* file descriptor */
  int dd_loc; /* offset in block */
  int dd_size; /* amount of valid data */
  char *dd_buf; /* directory block */
} DIR; /* stream data from opendir() */

#else

typedef struct {
  int d_fd; /* file descriptor */
  int d_loc; /* offset in block */
  int d_size; /* amount of valid data */
  char *d_buf; /* directory block */
} DIR; /* stream data from opendir() */

#endif /* !defined(__XOPEN_OR_POSIX) */

From sys/feature_tests.h​:

#if defined(_XOPEN_SOURCE) || defined(_POSIX_C_SOURCE)
#define __XOPEN_OR_POSIX
#endif

So your -D_POSIX_C_SOURCE=200112L on the Configure command-line appears to be preventing the detection of dd_fd.

What do you see for d_dir_dd_fd from your system perl​:

  perl -V​:d_dir_dd_fd

?

I suspect we need to add a Configure test for d_fd in the DIR structure.
