zsh-3.1.2-zefram3 - first experience

[Andrej Borsenkow <borsenkow.msk@xxxxxx>]

1. mkmakemod.sh scripts doesn't work with default OS /bin/sh. It *does*
work with zsh-3.1.2 in /bin/sh mode :-) I put set -x at the top:

gmake[1]: Entering directory `/SAM/home/bor/build/zsh-3.1.2-zefram3/Src'

I tried two shells (Bourne shell and XPG4 shell) and they bail out in
different places, but with the same message.


2. I don't quite understand what mkmakemod.sh does at the end. Here is
relevant part:

if $second_stage; then

    trap "rm -f $the_subdir/${the_makefile}" 1 2 15

    # config.status requires the pathname for the .in file to be relative
    # to the top of the source tree.  As we have it in the build tree, it
    # is necessary to construct an appropriate pathname.

    case $top_srcdir in
	/*) sdir=$top_srcdir ;;
	*) sdir=`pwd`/$top_srcdir; sdir=`echo $sdir | sed "$sed_normalise"` ;;
    esac
    top_builddir=`echo $sdir | sed -e 's,[^/][^/]*,..,g;s,^/,,'``pwd`

    CONFIG_FILES=$the_subdir/${the_makefile}:$top_builddir/$the_subdir/${the_makefile}.in CONFIG_HEADERS= ./config.status

My setup:

  /home -> /SAM/home
  srcdir = ~/src/zsh-3.1.2-zefram3 == /home/bor/src/zsh-3.1.2-zefram3
   (I run ~/src/zsh-3.1.2-zefram3/configure)
  builddir = ~/build/zsh-3.1.2-zefram3

Now, what hapens when script runs:

+ true
+ trap rm -f Src/Makemod 1 2 15
+ sdir=/home/bor/src/zsh-3.1.2-zefram3 
+ top_builddir=+ echo /home/bor/src/zsh-3.1.2-zefram3
+ top_builddir=+ sed -e s,[^/][^/]*,..,g -e s,^/,,
+ top_builddir=+ pwd
+ top_builddir=../../../../SAM/home/bor/build/zsh-3.1.2-zefram3 
+ CONFIG_FILES=Src/Makemod:../../../../SAM/home/bor/build/zsh-3.1.2-zefram3/Src/Makemod.in CONFIG_HEADERS= ./config.status
creating Src/Makemod
sed: Cannot open /home/bor/src/zsh-3.1.2-zefram3/../../../../SAM/home/bor/build/zsh-3.1.2-zefram3/Src/Makemod.in: No such file or directory
+ exit 0

The problem is, that `pwd' returns "true" pathname, but the srcdir has one
level hidden. I am not shure, if it is a problem of configure (which
should resolve given name) or mkmakemod.sh (ditto). Yes, I know, that I
can always run it in different way. But it should work this way as well.

2. mkmodindex.sh:

   At least my /bin/sh is not happy with [^xyz] pattern. Here is patch:

 		echo >&2 "WARNING: illegally named module \`$mod' in $dir"
 		echo >&2 "         (ignoring it)"
 		;;

3. makepro.awk fails. I am using nawk. It fails because of unquoted `{' -
it is metacaracter in extended regexp.

4. Finally, after I managed to compile it, I lost ZLE!!! All seems to
work, zle.so, comp1.so, compctl.so are loaded, bindkey shows all bindings,
but when I try to use *any* bound character, I get no effects. '^P' gives
fine message `'^P' not found" :-)

Any idea?
