Subject: gtkada: recompile with -fPIC

Hi,
I am following the plugin scheme from the GNAT examples, using GTK. So I
need gtkada, and for proper tasking with that, gtkada_contributions.
From the Adacore site I grabbed the actual versions (2020) of (binary)
GNAT and gtkada. From Dmitry's site I took the gtkada_contributions
source code.
The plugin scheme demands building standalone relocatable libraries
(loaded at runtime). So for making (on Linux) I call from a terminal:
gtkada-env.sh
export GTKADA_BUILD=relocatable
gprbuild -Pbase
My project file base.gpr withs gtkada_contributions_lib.gpr, which is
the original project file with the following additions:
for Library_Name use "gtkada_contributions";
for Library_Dir use "lib";
for Library_Kind use "relocatable";
The above gprbuild command now produces:
Build Libraries
[gprlib] gtkada_contributions.lexch
[link library] libgtkada_contributions.so
/opt/GNAT/2020/bin/../libexec/gcc/x86_64-pc-linux-gnu/9.3.1/ld:
/home/frank/Lib/Ada/gtkada_contributions/gdk-color-ihls.o: relocation
R_X86_64_32 against `.rodata' can not be used when making a shared
object; recompile with -fPIC
/opt/GNAT/2020/bin/../libexec/gcc/x86_64-pc-linux-gnu/9.3.1/ld:
/home/frank/Lib/Ada/gtkada_contributions/gdk-pixbuf-image.o: relocation
R_X86_64_32 against symbol `gdk__pixbuf__image__rgb_imageT' can not be
used when making a shared object; recompile with -fPIC
...
and a lot of other, similar lines.
Adding -fPIC to gtkada_contributions_lib.gpr (compiler switches) didn't
change anything, so I guess it is gtkada or even gtk which has to be
recompiled. Going ahead alone probably means hours of useless work with
the possible result of breaking my system.
So how can I compile/link my project?
Will then future projects without relocatable libraries still compile
and link?
