--- Comment #18 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-08-09 13:52:29 UTC --- The radr://6320843, "duplicate symbols from static libraries not properly ignored", has been open since 26-Oct-2008. I later opened radr://6733684, "duplicate symbols in static libs not properly ignored when linking in 10A###" with additional examples including... gcc -I/sw/include -DXNO_MTSAFE_STRINGAPI -DXNO_MTSAFE_PWDAPI -DXNO_MTSAFE_TIMEAPI -Wall -g -fno-strict-aliasing -Wno-unused -Wno-comment -fno-tree-ter -I/sw/include/freetype2 -I/sw/include -I/usr/X11/include -I/sw/include -I/sw/include -o wml wml.o -Wl,-framework -Wl,CoreServices -Wl,-framework -Wl,ApplicationServices -L/sw/lib -L/sw/src/fink.build/openmotif4-2.3.1-3/openmotif-2.3.1/tools/wml -lwml /sw/lib/libiconv.dylib -L/usr/X11R6/lib -lXt -L/usr/X11/lib -lXft -lXrender -lfontconfig /sw/lib/freetype219/lib/libfreetype.dylib -lX11 /sw/lib/libjpeg.dylib /sw/lib/libpng12.dylib -lz ld: duplicate symbol _main in /sw/src/fink.build/openmotif4-2.3.1-3/openmotif-2.3.1/tools/wml/libwml.a(wml.o) and wml.o from openmotif 2.3.0 and it was closed as a duplicate without additional comment. I don't think Apple views this as a critical bug but rather coddling lazy programmers.
