>Description:
I had tried downloading Insight GDB sources dated 07-18-2002 and built a sparc-elf version to run under Windows 2000 successfully. Then I compiled a small C program using my sparc-elf compiler. But when I loaded the compiled .o file into GDB, it showed only the assembly language window while the "Current function name" listbox showed the name "main" and the "Current file name" listbox was empty. If I selected the name of the source file from the "Current file name" listbox, then the source code would be displayed in full on the screen. However, when I clicked on the "-" next to a source line to set a breakpoint, no red circle breakpoint marker appeared. I was not sure whether my compiler was generating the wrong dwarf-2 debug info in the .o file or whether my GDB was not working properly. However, if I compiled with "-g2" to generate dwarf-1 level 2 debug info, I would not have the above problem inside GDB. I have attached my small source and .o file here.
I had asked this question on the Insight mailing list and someone told me this could be a problem inside GDB instead.
Thanks,
