Re: [Libguestfs] Gnulib setenv on Mac OS X bug?
Hi,

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)
This is normal. 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_setenv
This is expected too.
However, no rpl_setenv function is getting generated in libgnu.a
If 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.
