libcomerr: Uses automagic dependency on [g]awk, when available, breaking compile_et later on

[skymoo (Adam Mercer)]

kerberos5 @1.11_2 fails with:

:info:configure checking for compile_et... compile_et
:info:configure checking whether compile_et is useful... configure: error: execution failed

full build log attached.

Please attach config.log.

Attached.

Unfortunately the config.log isn't very helpful here:

configure:4705: checking for compile_et
configure:4721: found /opt/local/bin/compile_et
configure:4732: result: compile_et
configure:4747: checking whether compile_et is useful
configure:4754: error: execution failed

Can you try executing /opt/local/bin/compile_et yourself? What do the follwing commands print?

/opt/local/bin/compile_et
/sbin/md5 /opt/local/bin/compile_et
ls -lash /opt/local/bin/compile_et
ls -lash /opt/local/share/et/
port provides /opt/local/bin/compile_et

Interesting enough, your compile_et has a different md5 than mine. Can you attach it?

Since the output doesn't seem to help, I took a look at the autoconf macro that does the check:

# make sure compile_et provides "et_foo" name
cat >> conf$$e.et <<EOF
error_table foo
error_code ERR_FOO, "foo"
end
EOF
AC_CACHE_CHECK(whether compile_et is useful,krb5_cv_compile_et_useful,[
  if compile_et conf$$e.et >/dev/null 2>&1 ; then true ; else
    AC_MSG_ERROR(execution failed)
  fi
  AC_TRY_COMPILE([#include "conf$$e.h"],[&et_foo_error_table;],:,[AC_MSG_ERROR(cannot use et_foo_error_table)])
  # Anything else we need to test for?
  rm -f conf$$e.c conf$$e.h
  krb5_cv_compile_et_useful=yes
])

So it seems while compiling the file

error_table foo
error_code ERR_FOO, "foo"
end

with compile_et as the MacPorts user it returns a non-zero exit code on your system. Can you try compiling this file using compile_et? What does which awk print on your system?

[skymoo (Adam Mercer)]

[ram@cizin tmp]$ cat foo.et
error_table foo
error_code ERR_FOO, "foo"
end
[ram@cizin tmp]$ compile_et foo.et
/opt/local/bin/compile_et: line 43: gawk: command not found
mv: rename foo.h.45776 to foo.h: No such file or directory
chmod: foo.h: No such file or directory
/opt/local/bin/compile_et: line 50: gawk: command not found
mv: rename foo.c.45776 to foo.c: No such file or directory

I had recently uninstalled leaves and I think the gawk port was one of these. It looks like libcomer hardcodes the version of awk so a dependency on gawk should probably be declared.

I'll see if installing gawk fixes the problem

[skymoo (Adam Mercer)]

Yep, installing gawk allows me to install kerberos5

[neverpanic (Clemens Lang)]

So we can either add a dependency on gawk or make sure this uses /usr/bin/awk.

[skymoo (Adam Mercer)]

Assuming any awk will do ensuring it uses /usr/bin/awk seems like the right approach to me.

[neverpanic (Clemens Lang)]

Fixed in r103475.

I would have voted for adding the dependency on gawk, seeing as it's usually one of the first programs I install anyway ^{(because doing so makes the AC_PROG_AWK autoconf macro that most configure scripts use find something quicker)}, but whatever, this way works too I guess...

Why add an unnecessary dependency?

A premature optimization, if I’ve ever seen one.
