Re: Error while compiling on FreeBSD

[Riccardo Mottola]

Hi,

my tests were on FreeBSD 10, but I also have 8.x and 9.x available, I 
will test soon.

We have a problem on OpenBSD too

NSThread.m: In function '-[NSThread _setName:]':
NSThread.m:810:7: warning: passing argument 1 of 'pthread_set_name_np' 
from incompatible pointer type [enabled by default]

This the manpage on OpenBSD:
NAME
     pthread_set_name_np - set the name of a thread

SYNOPSIS
     #include <pthread.h>
     #include <pthread_np.h>

     void
     pthread_set_name_np(pthread_t thread, const char *name);

the test which runs successfully is:

how can I get from above which check is run? The relevant section is:

AC_CHECK_FUNCS(pthread_set_name_np)
if test $ac_cv_func_pthread_set_name_np == yes; then
  AC_DEFINE(PTHREAD_SETNAME(a,b), pthread_set_name_np(b),
    [Description: Define set name function for pthread])
else
  AC_CACHE_CHECK(
    [for pthread_setname_np() variant],
    [gs_cv_pthread_setname_np],
    [AC_LINK_IFELSE(
      [AC_LANG_PROGRAM([#include <pthread.h>],
        [pthread_setname_np(pthread_self(), "name");])],
        [gs_cv_pthread_setname_np=glibc],
        [AC_LINK_IFELSE(
          [AC_LANG_PROGRAM([#include <pthread.h>],
            [pthread_setname_np(pthread_self(), "%s", "name");])],
             [gs_cv_pthread_setname_np=netbsd],
             [gs_cv_pthread_setname_np=none])])])
  case $gs_cv_pthread_setname_np in
    glibc)
      AC_DEFINE(PTHREAD_SETNAME(a,b), pthread_setname_np(a,b),
        [Description: Define set name function for pthread])
      ;;
    netbsd)
      AC_DEFINE(PTHREAD_SETNAME(a,b), pthread_setname_np(a,"%s",b),
        [Description: Define set name function for pthread])
      ;;
  esac
fi

what is the =netbsd and =none part? What's the special part here for 
netbsd, which freebsd or openbsd perhaps need?
