ok, thank you every body for your opinion.  I will keep you in touch if I
discover a non-64bits line somewhere .... !

However .... I have a (maybe) stupid question on installation : I am trying to
compile glib, with gcc for 64 bits ( everything is already working fine for
glib/gtk with cc in 64 bits), with SGI linker.

In order to compile a 64 bits object, i need to define CFLAGS as -mabi=64. Ok,
no trouble, everything is compiling except .... at the end, when the Makefile
is trying to create the libraries. and then, I got some troubles with the
linker. I need to give the linker flag "-64",  in order to force the linker
mode in 64-bits-mode ( default is new 32 bits).

so i tried LFLGAS = -64, or LDFLAGS = -64 , and each time, i stop here :

/bin/sh ./libtool --mode=link gcc  -mabi=64 -Wall  -D_REENTRANT -64 -o
libglib.la -rpath /usr/local/lib -version-info 0:6:0     -release 1.2
-export-dynamic garray.lo gcache.lo gcompletion.lo gdataset.lo gdate.lo
gerror.lo ghash.lo ghook.lo giochannel.lo giounix.lo glist.lo gmain.lo gmem.lo
gmessages.lo gmutex.lo gnode.lo gprimes.lo grel.lo gscanner.lo gslist.lo
gstrfuncs.lo gstring.lo gtimer.lo gtree.lo gutils.lo
rm -fr .libs/libglib.la .libs/libglib.* .libs/libglib-1.2.*

gcc -shared  garray.o gcache.o gcompletion.o gdataset.o gdate.o gerror.o
ghash.o ghook.o giochannel.o giounix.o glist.o gmain.o gmem.o gmessages.o
gmutex.o gnode.o gprimes.o grel.o gscanner.o gslist.o gstrfuncs.o gstring.o
gtimer.o gtree.o gutils.o   -lc  -Wl,-soname -Wl,libglib-1.2.so.1 `test -n
"sgi1.5:sgi1.4:sgi1.3:sgi1.2:sgi1.1:sgi1.0:sgi1.6" && echo -Wl,-set_version
-Wl,sgi1.5:sgi1.4:sgi1.3:sgi1.2:sgi1.1:sgi1.0:sgi1.6` -Wl,-update_registry
-Wl,.libs/so_locations -o .libs/libglib-1.2.so.1.6

ld32: FATAL 12: Expecting n32 objects: garray.o is 64-bit.

does anyone know how I can do this ? ( I would like to keep my versions runing
on cc AND gcc )

Thanks

Laurent

Ps: Is this question more for gtk-app list ? Sorry if it is, but it seems to
be a Makefile trouble, so a gtk-devel problem ....
