Ruby building stuff broken with ltmain.sh

[frankie]

Final effect is:

make -f RubyMakefile.mk build

Please ignore -fPIC -DPIC additional flags, they are around as an obsolete patch for 1.4.4. (see my other report about that).

This issue is solved by updating local libtool (i.e. ltmain.sh) to a more recent version. I used that currently distributed on Debian sid, 1.5.24-2 which is

VERSION="1.5.24 Debian 1.5.24-2"
TIMESTAMP=" (1.1220.2.456 2007/06/24 02:25:32)"

It also solves the other issue about missing PIC definitions.

Err, note that even adding explicitly -shared at libtool call, it is ignored, which is the real issue...

same problem happened in ubuntu intrepid, this ldtool version is 2.2.4. see here: ​https://bugs.launchpad.net/ubuntu/+source/gdal/+bug/271670 gdal version is 1.5.2.

FYI this is the patch we are using since ages for 1.5 and 1.6 to allow Ruby building:

Another Ruby issue from the past. Wontfix?

Somehow related #1994 closed, closing this one also.
