Details:
A user of the SANE project has an issue with a generated configure script.
A reference to the original conversation is here:
https://gitlab.com/sane-project/backends/-/issues/468
They are running autoconf 2.71. Attached at the above bug report can be found
their generated configure script.
The issue seems to be related to the generation of this segment in a couple of
places which has invalid syntax:
...
for as_dir in $PATH
do
IFS=$as_save_IFS
case $as_dir in #(((
''
as_dir=./ ;;
*/) ;;
*) as_dir=$as_dir/ ;;
esac
for ac_exec_ext in '' $ac_executable_extensions; do
if as_fn_executable_p "$as_dir$ac_word$ac_exec_ext"; then
ac_cv_prog_CC="${ac_tool_prefix}gcc"
printf "%s\n" "$as_me:${as_lineno-$LINENO}: found
$as_dir$ac_word$ac_exec_ext" >&5
break 2
fi
done
...
IFS=$as_save_IFS
In other areas this segment has valid syntax:
...
for as_dir in $PATH
do
IFS=$as_save_IFS
case $as_dir in #(((
'') as_dir=./ ;;
*/) ;;
*) as_dir=$as_dir/ ;;
esac
for ac_exec_ext in '' $ac_executable_extensions; do
if as_fn_executable_p "$as_dir$ac_word$ac_exec_ext"; then
ac_cv_prog_CC="${ac_tool_prefix}cc"
printf "%s\n" "$as_me:${as_lineno-$LINENO}: found
$as_dir$ac_word$ac_exec_ext" >&5
break 2
fi
done
...
Any hints as to how we can track this down would be appreciated.
