[XviD-devel] MacOSX developers needed

[Edouard Gomez]

Hello,

my work on 0.9.1 tree is nearly finished now. However i would like the
MacOSX part to be working for this release. So i need the help from
people who know how to build dynlibs on this system.

Basically, the ./configure script is configuring the sources with that
(i added an option --disable-assembly in order to avoid gcc clash on ppc
assembly):

FEATURES=
ARCHITECTURE=-DARCH_IS_GENERIC
BUS=-DARCH_IS_32BIT
ENDIANNESS=-DARCH_IS_BIG_ENDIAN

CFLAGS=$(ARCHITECTURE) $(BUS) $(ENDIANNESS) $(FEATURES) -Wall -O2 -fPIC \
       -fomit-\frame-pointer -ffast-math -funroll-loops -fschedule-insns \
       -fschedule-insns2

SHARED_EXTENSION=dylib
STATIC_EXTENSION=a
OBJECT_EXTENSION=o

OS_LDFLAGS=-dynamiclib

And the final linking stage uses:

$(STATIC_LIB): $(OBJECTS)
        ar rc $(STATIC_LIB) $(OBJECTS)

$(SHARED_LIB): $(OBJECTS)
        $(CC) $(LDFLAGS) $(OBJECTS) -o $(SHARED_LIB) $(OS_LDFLAGS)

But i obtain that errors:

ld: common symbols not allowed with MH_DYLIB output format

[...]
/usr/bin/libtool: internal link edit command failed
make: *** [libxvidcore.dylib] Error 1

I wonder why the linker is complaining about common definitions of these
symbols. As we all (should) know, the code is error free (of this kind
at least) for ages. So what i am supposed to do to avoid these errors.

PS: the tested platform is the macosx server edition on sourceforge
    compile farm.
