Which will leed to this backported patch (attached) for our folks using
libtool-devel-1.5.10-1. (patch uses absolute paths)
libtool-2cvs is a bit advanced, but this is essentially what charles
patch did.
It did help on re-building gdal, esp. in the make install step.
I will also check on my other failing packages. (libming, php)
But it didn't help on another (related?) new cygwin libtool problem:
Sometimes it switches to .exe instead of .dll. Will investigate this
further. My current theory is that -o <soname> just missed the .dll
extension and .exe is then taken as default.
/bin/sh.exe ./libtool --mode=link g++ $LIBS
-Wl,--enable-runtime-pseudo-reloc -o libgdal.la ./gcore/*.lo ./port/*.lo
./alg/*.lo ... \
-rpath /usr/lib \
-no-undefined \
-version-info 5:1:4

^^^ .dll missing!
-Wl,--out-implib,.libs/libgdal.dll.a
does this ring a bell somewhere? $output missing the extension.
I see in one code section that for case $linkmode prog) the .exe
extension and then any extension is stripped.
case $linkmode in
...
prog)
case $host in
*cygwin*) output=`$echo $output | ${SED} -e 's,.exe$,,;s,$,.exe,'` ;;
esac
but we are in linkmode=lib.
and this is the failing place, exactly after your patch:
if test "$wrappers_required" = no; then
# Replace the output file specification.
compile_command=`$echo "X$compile_command" | $Xsed -e
's%@OUTPUT@%'"$output"'%g'`
$output misses the ".dll"
I would rather use something like this:
compile_command=`$echo "X$compile_command" | $Xsed -e
's%@OUTPUT@%'"$output_objdir/${outputname}${shrext}"'%g'`
correct?
