"make check" fails in "doc" on a vanilla NetBSD5.0 system (released
yesterday) because no version of Perl is installed by default. In
fact make fails without explanation:
$ make check
*** Error code 1
Stop.
make: stopped in /home/james/tmp/cu/coreutils-7.2.66-428db1/doc
I guess this is because some failing command starts with @. Anyway,
re-running with make debugging turned on, we find that the problem is
that although configure determined that Perl was missing, it still
decides to run it:
$ make -d A check
[...]
*** Failed target: sc-lower-case-var
*** Failed command: /bin/ksh
/home/james/tmp/cu/coreutils-7.2.66-428db1/build-aux/missing --run
perl -e 1 2> /dev/null && /bin/ksh
/home/james/tmp/cu/coreutils-7.2.66-428db1/build-aux/missing --run
perl -lne '/\...@var{/ or next; while (/\...@var{(.+?)}/g) { $v = $1; $v =~
/[A-Z]/ && $v !~ /^\\/ and (print "$ARGV:$.:$_"), $m = 1 } END {$m and
(warn "doc/Makefile: do not use upper case in \...@var{...}\n"), exit 1}'
./*.texi
*** Error code 1
Stop.
make: stopped in /home/james/tmp/cu/coreutils-7.2.66-428db1/doc
Applying :@ to ""
Result of :@ is ""
I believe the cause is not that I changed a timestamp and hence forced
a generated file to be regenerated, but simply that "make check" will
fail without Perl:
doc/Makefile contains:
syntax_checks = \
sc-avoid-io \
sc-avoid-non-zero \
sc-avoid-timezone \
sc-avoid-zeroes \
sc-exponent-grouping \
sc-lower-case-var \
sc-use-small-caps-NUL
[...]
sc-lower-case-var:
@$(PERL) -e 1 2> /dev/null && \
$(PERL) -lne $(find_upper_case_var) $(srcdir)/*.texi
