I received the URL to update my Bugzilla password and it accepted it but I still cannot login. "The username or password you entered is not valid." comes up each time I try. I'm now running AIX 6.1, oslevel -s returns 6100-06-03-1048 and the problem seems to persist with newer versions of gcc as well. I installed gcc 4.4.6 today after having issues trying to build GNU barcode from source. gcc -v Using built-in specs. Target: powerpc-ibm-aix6.1.0.0 Configured with: ../gcc-4.4.6/configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --enable-languages=c,c++,fortran --prefix=/opt/freeware --enable-threads --enable-version-specific-runtime-libs --disable-nls --enable-decimal-float=dpd --host=powerpc-ibm-aix6.1.0.0 Thread model: aix gcc version 4.4.6 (GCC) The original Makefile includes -g among the CFLAGS, which produces the now well documented error message from the AIX assembler as noted in this thread. After revisiting the GCC Bugzilla site today, I added initializations for all the Static variables in the source code files that were not arrays and were not already initialized and then I tried to recompile with -g in the CFLAGS. This attempt now fails with the also reported message: ... /usr/bin/gcc -g -std=gnu89 -O2 -Wall -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_UNISTD_H=1 -DHAVE_STRCASECMP=1 main.o cmdline.o -L. -lbarcode -lpaper -lm -o barcode ld: 0711-596 SEVERE ERROR: Object main.o An RLD for section 2 (.data) refers to symbol 944, but the storage class of the symbol is not C_EXT or C_HIDEXT. collect2: ld returned 12 exit status make: *** [barcode] Error 1 The only way to get a successful compile under AIX 6.1 TL 3 with IBM's fix-du-jour is to remove -g from the CFLAGS. Here is the top of the GNU barcode Makefile, the rest is standard install targets etc. # # This Makefile should run fine with both pmake and gmake # CC = /usr/bin/gcc CFLAGS = -std=gnu89 -O2 -Wall -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_UNISTD_H=1 -DHAVE_STRCASECMP=1 RANLIB = /usr/bin/ranlib INSTALL = /opt/freeware/bin/install -c LDFLAGS = -L. -l$(TARGET) -lpaper -lm prefix = /opt/freeware BINDIR = $(bindir) LIBDIR = $(libdir) INCDIR = $(includedir) MANDIR = $(prefix)/share MAN1DIR = $(mandir)/man1 MAN3DIR = $(mandir)/man3 INFODIR = $(infodir) # getopt may be installed or not, if not take our copy GETOPT_O = TARGET = barcode LIBRARY = lib$(TARGET).a MAN1 = $(TARGET).1 MAN3 = $(TARGET).3 #INFO = doc/$(TARGET).info HEADER = $(TARGET).h LIBOBJECTS = library.o ean.o code128.o code39.o code93.o i25.o \ msi.o plessey.o codabar.o \ ps.o pcl.o code11.o fonts.o EXEOBJECTS = main.o cmdline.o $(GETOPT_O) ALLSOURCES = $(LIBOBJECTS:.o=.c) $(EXEOBJECT:.o=.c) #Hmm...

I can compile programs that don't have static variables with -g, but I get a coredump when I tried to debug them. I can try to create a simple test case if this is not a known bug. Thanks, Richard Nolde
