Hi, I'm cross-compiling DirectFB 1.2.3 on an ARC processor
(arc-uclibc-linux).
In the beginning I got a "multiple definition" error with __init() and
__fini(), since 'make' was trying to create libfusion.so-1.2.so.0.3.0,
linking it against crti.o and libdirect.so (which was already linked to
crti.o).
I got rid of this error by modifying my libtool script around line 2800:
# Get the name of the library we link against.
linklib=
for l in $old_library $library_names; do
linklib="$l"
done
if test -z "$linklib"; then
$echo "$modename: cannot find name of link library for
\`$lib'" 1>&2
exit $EXIT_FAILURE
fi
# HACK NOT TO LINK linklib AGAINST crti.o # MODIFIED (ADDED)
found_libfusion="no"
linklib=$linklib\ -nostartfiles # MODIFIED (ADDED)
echo "[ $LINENO ] --> linklib: $linklib" # MODIFIED (ADDED)
# This library was specified with -dlopen.
if test "$pass" = dlopen; then
if test -z "$libdir"; then
(etc...)
This removed crti.o from the linking process... I hope it works.
Now I have another - more annoying - error when making
libdirectfb-1.2.so.0.3.0:

[continues........]
So here's the situation:
sources + crti.o => libdirect.so [MADE]
sources + (crti.o) + libdirect.so => libfusion.so [FIXED
ERRORS]
sources + (crti.o) + libdirect.so + libfusion.so => libdirectfb.so [ERRORS!]
Any suggestion on how can I fix this errors?

Piero
