Version: 2.64-3
Severity: important
Justification: ftbfs with dash from experimental
Tags: upstream
Hi,
Trying to build autoconf2.64 with dash 0.5.6.1-1~exp2 as /bin/sh, I
get
checking for GNU M4 that supports accurate traces... configure: error:
no acceptable m4 could be found in $PATH.
GNU M4 1.4.6 or later is required; 1.4.13 is recommended
make: *** [configure-stamp] Error 1
This is because configure does
ac_snippet=change'quote(<,>)in''dir(<if''def>,mac,bug)'
ac_snippet=${ac_snippet}pat'subst(a,\(b\)\|\(a\),\1)d'nl
test -z "`$ac_path_M4 -F conftest.m4f </dev/null 2>&1`" \
&& test -z "`echo $ac_snippet | $ac_path_M4 --trace=mac 2>&1`" \
&& test -f conftest.m4f \
&& ac_cv_path_M4=$ac_path_M4 ac_path_M4_found=:
and expects bash's behavior (backslashes preserved rather than being
used for escape sequences) which is not portable.
Suggested fix: patch m4/m4.m4 to use $as_echo. Or set CONFIG_SHELL
in debian/rules.
Thanks for keeping the toolchain working well.
Jonathan
