‘libunistring’ module errors

[Ludovic Courtès]

Hello!

With the current ‘libunistring’ Gnulib module, I’m observing [0] this
during the ‘configure’ run:

--8<---------------cut here---------------start------------->8---
./configure: line 20186: test: -lt: unary operator expected
./configure: line 20187: test: -eq: unary operator expected
./configure: line 20223: test: -lt: unary operator expected
./configure: line 20224: test: -eq: unary operator expected

[...]

--8<---------------cut here---------------end--------------->8---

stemming from these lines:

--8<---------------cut here---------------start------------->8---
            test $LIBUNISTRING_VERSION_MAJOR -lt 0 \
            || { test $LIBUNISTRING_VERSION_MAJOR -eq 0 \
                 && { test $LIBUNISTRING_VERSION_MINOR -lt 9 \
                      || { test $LIBUNISTRING_VERSION_MINOR -eq 9 \
                           && test $LIBUNISTRING_VERSION_SUBMINOR -lt 2
                         }
                    }
               }
--8<---------------cut here---------------end--------------->8---

Before, ‘configure’ reported this:

--8<---------------cut here---------------start------------->8---
checking for libunistring... yes
checking how to link with libunistring... -lunistring
checking for libunistring version... 0.9.3
--8<---------------cut here---------------end--------------->8---

So, two problems here:

  1. The tests above are underquoted, they should read:

       test "$LIBUNISTRING_VERSION_MAJOR" -lt 0 \
          ...

  2. The version-extraction sed scripts appear to be broken:

--8<---------------cut here---------------start------------->8---
$ 
gl_libunistring_sed_extract_subminor='/^[0-9][0-9]*[.][0-9][0-9]*[.][0-9]/{s/^[0-9]*[.][0-9]*[.]\([0-9]*\).*/\1/p;q;}
> i\
> 0
> q
> '

$ echo 0.9.3 | sed -n -e "$gl_libunistring_sed_extract_major"

$ sed --version
GNU sed version 4.1.5
--8<---------------cut here---------------end--------------->8---

Ideas?

Thanks,
Ludo’.
