Thanks to Chris and Josh, I have gotten a little further- at least in
providing info that will hopefully help someone help me along even
further. I got "date +%z" to work, it correctly tells me -0500. But
"date +%Z" outputs nothing, because it "there is no determinable timezone".
I got "info date" to work, but I didn't find out how to set the timezone
(%Z). It seems that "date --set=xxx" doesn't affect the timezone.
AFAICT, I am going to have to write a c file that will call tzset() to
set the timezone correctly- best case I do this once, and the timezone
stays forever set, worst case I have to include it to compile fileutils
and sh-utils (and anything else that relies on time, strftime etc).
But I am concerned that fileutils and sh-utils actually do compile OOTB
for everyone else, and there is some lurking problem with my system that
this hack of calling tzset() will only workaround in this case.
I would appreciate any ideas of what the root problem is, or even a
definitive "fileutils and sh-utils will compile OOTB" or "they won't
compile OOTB".
TIA,
Peter

My original message -------------
I am trying to compile fileutils and sh-utils, and I am getting an error-
gcc -g -O2 -o dir ls.o ls-dir.o ../lib/libfetish.a -lintl
../lib/libfetish.a(strftime.o): In function `strftime_copytm':
/cygdrive/d/f-comp/fileutils-4.1-1/build/lib/../../lib/strftime.c:1270:
undefined reference to `_tzname'
I read a bunch of messages in the archives, and one about "You must
declare tzname as __attribute__((dllimport)) or __declspec(dllimport),
or else it won't link" but I don't know how or where to do this (I
haven't made any changes to the source yet, and wanted to verify that it
would compile OOTB first).
I can't get "date %z" or "date %Z" to work on the command line in a bash
shell, it just says "date: invalid date `%Z'". I can't seem to set the
date with a timezone- the man page doesn't provide the format, and "info
date" tells me "info: dir: No such file or directory" (I haven't used
info before). My attempts to do "date --set=Mon Nov 5 17:10:49 2001 EST"
managed to change the date to yesterday, 11pm. My NT clock says that my
timezone is GMT -0500 Eastern Time.
There is an #ifdef _LIBC at the beginning of strftime.c that ends up
defining _tzname, but I don't think _LIBC is defined, and I can't find
where it would be defined. I tried removing the #ifdef and forcing
_tzname to get defined, but that gave many more errors.
I hope there is something big that I am missing, like an important
include file that defines _LIBC and I just didn't pick it up in the
configure.
