[Message part 2 (message/rfc822, inline)]
So, here's a proposed patch to fix this. It adds more output (on
stderr) in the case of failure. It does not change the output in the
case of success.
I installed it. Saw nothing to change, and make distcheck still
succeeded. Thanks as always, Bruno. -k

[Message part 4 (text/plain, inline)]
Automake provides a useful 'installcheck' implementation for
packages that install programs: It runs each program twice,
once with option '--help' and once with option '--version'.
Here is a sample output:
make[2]: Entering directory '/work/gettext-2025-06-19/build/gettext-tools/src'
bad=0; pid=$$; list="msgcmp msgfmt msgmerge msgunfmt xgettext msgattrib msgcat msgcomm msgconv msgen msgexec msgfilter msggrep msginit msguniq recode-sr-latin"; for p in $list; do \
case ' ' in \
*" $p "* | *" ../../../gettext-tools/src/$p "*) continue;; \
esac; \
f=`echo "$p" | \
sed 's,^.*/,,;s/$//;s,x,x,;s/$//'`; \
for opt in --help --version; do \
if "/usr/local/bin/$f" $opt >c${pid}_.out \
2>c${pid}_.err </dev/null \
&& test -n "`cat c${pid}_.out`" \
&& test -z "`cat c${pid}_.err`"; then :; \
else echo "$f does not support $opt" 1>&2; bad=1; fi; \
done; \
done; rm -f c${pid}_.???; exit $bad
msgcmp does not support --help
msgcmp does not support --version
msgfmt does not support --help
msgfmt does not support --version
...
make[2]: *** [Makefile:5076: installcheck-binPROGRAMS] Error 1
The problem with this output is that it gives no clue regarding the reason
of the failures. Each program invocation can fail due to
- an exit status != 0,
- an stdout output that is empty (not expected for --help or --version), or
- some stderr output,
but it does not tell which of these actually caused the failure. And it
erases the log files just before the end of the rule execution ('exit $bad').
Nowadays it is quite frequent to do builds on machines in the "cloud", that
is, on machines that
- are allocated to the developer only for the time of the build,
- don't offer the possibility for interactive login and investigation
to the developer.
In other words, the Automake rule above was written with the assumption
"if the program invocation fails, the developer can investigate it locally".
But this assumption is not valid any more. In my case, not only I can't
login to the cloud machine. I also cannot reproduce the issue locally,
because the environment is a complex setup with docker.
So, here's a proposed patch to fix this. It adds more output (on stderr)
in the case of failure. It does not change the output in the case of success.
In the case above, the output was changed to:
make[2]: Entering directory '/work/gettext-2025-06-20/build/gettext-tools/src'
bad=0; pid=$$; list="msgcmp msgfmt msgmerge msgunfmt xgettext msgattrib msgcat msgcomm msgconv msgen msgexec msgfilter msggrep msginit msguniq recode-sr-latin"; for p in $list; do \
case ' ' in \
*" $p "* | *" ../../../gettext-tools/src/$p "*) continue;; \
esac; \
f=`echo "$p" | \
sed 's,^.*/,,;s/$//;s,x,x,;s/$//'`; \
for opt in --help --version; do \
"/usr/local/bin/$f" $opt \
>c${pid}_.out 2>c${pid}_.err </dev/null; \
xc=$?; \
if test -n "`cat c${pid}_.err`"; then \
echo "$f does not support $opt: error output" 1>&2; \
cat c${pid}_.err 1>&2; \
bad=1; \
else \
if test -z "`cat c${pid}_.out`"; then \
echo "$f does not support $opt: no output" 1>&2; \
bad=1; \
else \
if test $xc != 0; then \
echo "$f does not support $opt: exit code $xc" 1>&2; \
bad=1; \
else \
:; \

This more detailed output allowed me to understand the problem
(a missing /etc/ld.so.conf entry or a missing 'ldconfig' invocation)
and add a fix/workaround.
