FW: Need help to compile coreutils-5.96

[Olivier Langlois]

Hi,

When compiling this package, I receive this error message from the linker:

gcc -std=gnu99  -g -O2   -o cp.exe  cp.o copy.o cp-hash.o ../lib/libcoreutils.a
  ../lib/libcoreutils.a
copy.o:copy.c:(.text+0xefd): undefined reference to `_cygwin_spelling'
copy.o:copy.c:(.text+0x2b38): undefined reference to `_cygwin_spelling'
collect2: ld returned 1 exit status

Does someone have any idea about what is wrong?

Thank you,
Olivier Langlois

autoreconf runs both automake and autoconf, as needed.

I already did - quoting /usr/share/doc/Cygwin/coreutils-5.96.README:

Additional build conditions (these or newer):
  autoconf2.5-2.59-2

That warning was the key.  Automake has to be run during the prep state.
Running configure is not enough; you should try running 'autoreconf' prior
to configure, to guarantee that you pick up changes to Makefile.am.  Or,
now that you have automake (and I hope autoconf) installed, rerun the prep
stage.

Eric,

I think that I have found the problem. In the file lib/Makefile.am, you
have

libcoreutils_a_SOURCES = \
  allocsa.c allocsa.h \
  euidaccess.h \
  exit.h \
  fprintftime.c fprintftime.h \
  full-read.c full-read.h \
  full-write.c full-write.h \
  getaddrinfo.h \
  gettext.h \
  localcharset.c localcharset.h \
  mbchar.h \
  mbswidth.c mbswidth.h \
  mbuiter.h \
  readtokens0.c readtokens0.h \
  strcase.h \
  strnlen1.c strnlen1.h \
  strstr.h \
  time_r.c time_r.h \
  unicodeio.c unicodeio.h \
  verify.h \
  xalloc-die.c \
  xgethostname.c xgethostname.h \
  xmemcoll.c xmemcoll.h \
  xstrndup.c xstrndup.h \
  xstrtoimax.c \
  xstrtoumax.c

libcoreutils_a_SOURCES += \
  printf-args.h \
  printf-parse.h \
  vasprintf.h \
  vasnprintf.h \
  cygwin.c cygwin.h

Somehow, when lib/Makefile is generated by configure, cygwin.c is not
included in the Makefile. I did not have automake installed and a
warning has been issued during make. I have tried to install automake
and rerun configure but I still have the same result where cygwin.c is
not compiled.

RE: FW: Need help to compile coreutils-5.96

[Olivier Langlois]

Hi,

What you say makes sense. I have run coreutils-5.96-1.sh first and it
did not complete correctly because I did not have patch installed. I
have downloaded patch and then executed the script again thinking that
it would overwrite what the first attempt did. I will try to redo the
whole process from scratch and If I still have the problem, I'll come
back to report it.

BTW, it is the first time I try to compile a cygwin package and I'm
really amazed how easy it is. I used to have bad experiences with
compiling stuff on Unix but with your package, everything went very
smooth and flawlessly except for my small glitch.

Nice job!

It sounds like you did not properly run the /usr/src/coreutils-5.96-1.sh
script to prep the source with my downstream patches.  cygwin_spelling()
is a function I wrote, provided in lib/cygwin.c which is part of my patch,
and should be linked in to lib/libcoreutils.a if the package is properly
re-autotooled during the prep stage.
