Re: guile-1.8.1 build fails at libguile/filesys.c on Solaris2.6

Hi,

Sorry for the late answer.

This means either that `HAVE_STAT64' gets defined at configure-time
while it shouldn't (unlikely), or that some additional macro needs to be
defined for Solaris to provide the actual function prototypes (more
likely), or that some of the feature macros we define are mutually
exclusive (e.g., `_LARGEFILE64_SOURCE' is not compatible with some other
thing).

The error message you copied does not mention `dirent_r ()', can you
explain what's wrong with it?

`_GNU_SOURCE' cannot do any harm on Solaris I guess.  ;-)

`_LARGEFILE64_SOURCE' should normally have the same effect on Solaris as
on GNU.  Can you please try to compile a C source file along the lines
of:

  #define _LARGEFILE64_SOURCE

  #include <sys/types.h>
  #include <sys/stat.h>
  #include <fcntl.h>

  int
  main (int argc, char *argv[])
  {
    struct stat64 st;

    return (stat64 ("/etc/fstab", &st));
  }

(Note: You could also probably compile the whole thing without
`-Werror'...)

Thanks,
Ludovic.
