Chris, thanks for your response. In answer to you're question about if it is necessary to use the stabs debugging format - I've no clue. I'm merely trying to build my project in an ON tree and this setting was inhereted from the top level makefile. I'm on version 106 and here is snippet of usr/src/Makefile.master:
# # Default debug format for Sun Studio 11 is dwarf, so force it to # generate stabs. # DEBUGFORMAT= -xdebugformat=stabs # # Flags used to build in debug mode for ctf generation. Bugs in the Devpro # compilers currently prevent us from building with cc-emitted DWARF. # CTF_FLAGS_sparc = -g -Wc,-Qiselect-T1 $(C99MODE) $(CNOGLOBAL) $(CDWARFSTR) CTF_FLAGS_i386 = -g $(C99MODE) $(CNOGLOBAL) $(CDWARFSTR) CTF_FLAGS = $(CTF_FLAGS_$(MACH)) $(DEBUGFORMAT) I tried commenting out the DEBUGFORMAT line and my re-making my application. It appeared to work find (including proper debug info so dbx could see sources). Proper setting of these flags for ON is outside of my area of expertise so I'm not sure if commenting out that line is the correct fix or not. Are other developers working on the ON tree seeing this same issue?
