I recently encountered this problem while using gcc/gcj 4.5 with ecj-4.5.jar to compile the pdftk utility (http://www.accesspdf.com/pdftk/) on FreeBSD. I maintain the pdftk port for FreeBSD, and I previously used gcc/gcj 4.2 with ecj-4.3.jar without any problems. I found a workaround by patching the pdftk Makefiles like so: ## # implicit rules for creating A from B %.o : %.java $(GCJ) $(GCJFLAGS) -c $< -o $@ + ${OBJCOPY} -L '_ZGr8_$$_dummy' $@ The FreeBSD objcopy command changes the .dummy resource from global scope to local scope in each .o file. After doing that, the pdftk link phase succeeded instead of dying with a ton of "duplicate symbol" errors. After searching for the source of the duplicate symbol, I think I found it here: http://gcc.gnu.org/ml/java-patches/2009-q1/msg00049.html If the patch included in this message is the source of the duplicate symbol problem, then I wonder if it could be fixed like so? String someRandomString = <generate random string>(); ZipEntry entry = new ZipEntry(".dummy" + someRandomString); Feedback welcome, Greg Larkin -- glarkin at FreeBSD dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |glarkin at FreeBSD dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42143
