There seems to be a bug in Gnulib's setenv module on Mac OS X. At
configure time it says:
checking whether setenv validates arguments ... no
(The test program it is running is:
| int
| main ()
| {
|
| if (setenv ("", "", 0) != -1) return 1;
| if (errno != EINVAL) return 2;
| if (setenv ("a", "=", 1) != 0) return 3;
| if (strcmp (getenv ("a"), "=") != 0) return 4;
|
| ;
| return 0;
| }
and this returns status code 4)
As a result, in stdlib.h, this:
#if @GNULIB_SETENV@
# if @REPLACE_SETENV@
# undef setenv
# define setenv rpl_setenv
is replaced by:
#if 1
# if 1
# undef setenv
# define setenv rpl_setenv
However, no rpl_setenv function is getting generated in libgnu.a, so
of course the program fails to link.
Any ideas?
Rich.

It's a small bug in the system's setenv routine.> As a result, in stdlib.h, this: > > #if @GNULIB_SETENV@ > # if @REPLACE_SETENV@ > # undef setenv > # define setenv rpl_setenv > > is replaced by: > > #if 1 > # if 1 > # undef setenv > # define setenv rpl_setenvThis is expected too.> However, no rpl_setenv function is getting generated in libgnu.aIf you do $ grep LIBOBJ config.status you should see something like this: S["gl_LTLIBOBJS"]=" setenv.lo" S["gl_LIBOBJS"]=" setenv.o" If you do $ grep -i _setenv config.status you should see something like this (among others): S["REPLACE_SETENV"]="1" S["HAVE_SETENV"]="1" S["GNULIB_SETENV"]="1" If not, then please show the details.

BTW, OS X by default comes with an ancient version of autoconf, 2.61, if that affects things.
